Oha, I thought the DHL delivery included near-field monitors and not the all-tube SVT bass stop part from Ampeg. It is really rare that the parcel carrier pushes 2 boxes with a total of almost 50 kg in the hand and the inscription on the package promises a near-field monitor as content. Be that as it may, KS Digital must have thought of something when manufacturing its KS Digital C88-Reference to equip this monitor with such a high weight.
The setup of the KS Digital C88-Reference test
The first thing to do is to find the right speaker for the right side, as the speakers come in a left and a right version, but this is very easy to figure out. As always when positioning a monitor vertically, place the tweeters to the outside and in this case make sure the KSD logo is placed at the bottom. The speakers are placed on Gravity Stand monitor stands at a height of about 1 meter. The distance to the monitoring position is 150 cm, the distance to the wall behind is 200 cm. A Palmer Monicon acts as the master volume control, and all the cabling is from Cordial. The control room is moderately damped with Basotect panels and was covered with a short-pile carpet.
The concept of the KS Digital C88-Reference
The KS Digital C88-Reference is an active, 3-way nearfield monitor, which features an 8-inch Kevlar woofer with 175-watt Class-D power amp, an 8-inch midrange driver, also made of Kevlar with 175-watt Class-D power amp, and a 1-inch fabric dome tweeter with 80-watt Class-D power amp (all peak values), and according to the manufacturer, has a frequency response of 32 Hz - 22 kHz. The midrange and tweeter are coaxial in design to come as close as possible to the ideal of a point source of sound. The sound pressure of the system is specified at 118 dB SPL. To protect all components against overload, the system was equipped with electronic peak/thermal limiter protection circuits, separately for all drivers.
The weight of the speakers is 22 kg per speaker, which makes the loudspeaker with dimensions of 480 mm x 240 mm x 310 mm one of the real heavyweights, but at the same time minimizes the cabinet bounce. The system is designed for small to medium-sized control rooms, whereby there should be a minimum distance of 50 cm to the speaker in the listening position. The speaker does not have a bass reflex port and can therefore be positioned comparatively close to a wall without having to interfere with the system's sound control.
The actual special feature of the KS Digital C88-Reference is the digital processing of the signal, which is done with Finite Impulse Reponse Technology, or FIRTEC for short. The internal processor constantly checks the system and tries to minimize distortion and ensure maximum phase fidelity. Furthermore, the processor manages six user-defined memory locations, which can be accessed via an optionally available remote control called KSD-RC. A delay correction can also be called up via this. An additional remote control called KSD-VOL, which can also be purchased as an option, allows direct volume control by +/- 6 dB without an additional monitor controller.
Optics and connections of the KS Digital C88-Reference
The first impression of the KS Digital C88-Reference is really very good. All components give a high-quality impression, all screw connections and transitions are clean and professionally executed, as is to be expected in this price range, the cherry wood veneer provides a dignified appearance. If you activate the box, a glowing KSD logo informs you about the status of the system. Unfortunately, the KS Digital C88-Reference does not have an auto-standby function.
The rear panel of the KS Digital C88-Reference is very clearly laid out, although appropriate for its field of application, somewhat unusual in comparison to a home recording speaker. On the one hand, the system does without an additional input jack beyond XLR, since no other format is used in the professional field anyway. Also, the use of an RJ45 jack will probably only be found very rarely in the budget sector, but in this case it only serves to connect the already mentioned remote controls. Behind a small, transparent plastic disk are 3 small thumbscrews, with which the high and low range, both as shelving filters, and a volume control, with which a volume balance can be carried out with unbalanced set-up.
Also worth mentioning is the very tight suspension of the woofers, which in the passive range means either a reduced bass response, or a safeguard for very high volumes. To what extent this suspension should affect the sound characteristics of the system remains to be seen in the practical test.
The KS Digital C88-Reference in practice
Already the first tones from the system provide a real ohhh effect. Without any further sound corrections, the KS Digital C88-Reference already delivers an excellent basic sound that can easily compete in the next higher league from €2,000 per speaker in terms of reproduction.
Starting with a bass reproduction that makes the listener constantly search for a subwoofer without finding it. Quite contrary to the hard suspension of the woofer, the system offers a balanced, neutral and, above all, tight bass foundation even below 100 Hz, which never loses definition at any time or at any volume. In general, the goal of the Saarland company, a neutral reproduction of the source material without "sounding" has been achieved here across the board.
Accompanied by an even midrange reproduction, which even the extremely difficult-to-define high-gain guitars master well up to the treble range, which draws attention neither by an exaggerated silkiness, nor by sharp or harsh scratching. Even after a short time, one notices how relaxing it is to work with the KS Digital C88-Reference speakers. Due to the high resolution, you don't have to explicitly send your hearing in search of the instrument / frequency or similar to be analyzed, it is virtually delivered on a silver platter by the system.
Let's move on to the spatial resolution and depth gradation. Here, too, the system convinces with a convincing performance, from the clean puncturing of the phantom center to a very even staggering of the sound material. Not only is a real band captured very nicely in the stereo image with the appropriate sound material, even outdoor recordings made with high-quality stereo technology leave a very vivid auditory impression. It would be interesting to test the KS Digital C88-Reference in a 5.1 environment, but unfortunately I was not able to do so.
However, the impulse behavior has to be considered the highlight of the system. It is more than just impressive how fast the speakers react to the delivered signal. Which of the installed components is exactly responsible for this, or the final combination of them, I can't say exactly. However, it is a fact that the comparatively hard suspension of the speakers in cooperation with the FIRTEC system enables a very high impulse fidelity.
Hard and fast following signals such as kick drums or even percussive elements from the keyboard faction manage the KS Digital C88-Reference with unprecedented ease even at high volumes. Reference productions such as Peter Gabriel's "So" appeared with their opulent, slightly overloaded eighties clutter in a very transparent sound garment, while many competitors completely go to pieces here in terms of resolution.
Whether the impulse fidelity can also be attributed to the comparatively high weight of the speaker cannot be determined exactly. However, it is certain that with a correspondingly high potential energy, the resonator does not move as fast as a body with a correspondingly lower weight, even with strong impulses.
Conclusion
With the KS Digital C88-Reference, the Saarland-based company has succeeded in creating a real highlight in the near-field monitor sector. The system sounds much higher quality than the price of just under 1,300 euros would suggest.
With a very neutral sound reproduction, a very balanced frequency response, an excellent depth gradation and a phenomenal impulse behavior, the digital system plays in a league that is otherwise only available for 2,000 euros and more per speaker.
The system convinces with a universal suitability for all music genres, whereby especially percussive-heavy productions with great depth staggering benefit from the concept. It's just a pity that the advanced functions, such as saving and calling up the parametric presets and the extended volume control, can only be managed via an optionally available remote control.

TEST: KS Digital C-88 Reference
TEST: KRK V6S4 - V8S4
When it comes to visual trademarks, the speakers of the manufacturer KRK, which now belongs to the Gibson Group, are all at the forefront. In what feels like the third studio in the world, the classic yellow Kevlar woofers shine out at you, setting not only visual but also acoustic trademarks.
The quite successful V-series is now entering its 4th generation and has some very interesting developments behind it in the context of the MK4 introduction. The user has a choice of three speaker sizes (KRK V8S4, KRK V6S4, KRK V4S4) and a KRK 12S subwoofer, with the first number reflecting the size of the woofer in inches, as expected. The VXT series, which was previously considered the third generation, will now continue as an independent series. We have the KRK V8S4 and KRK V6S4 versions for testing. With a retail price of 599 euros for the V6 variant and 799 euros for the V8 variant, KRK addresses the ambitious user, for whom the Rokit series is sonically too much in the budget range.
Construction
The basic construction of the two near-field monitors are quickly listed, but at first glance they do not stand out particularly from the previous KRK catalog. Both systems have electronic crossovers and 2 Class D power amplifiers each with a total of 155 watts (V6S4 - LF 125 watts, HF 30 watts), respectively 230 watts (V8S4 - LF 200 watts, HF 30 watts) and are designed as classic bass reflex boxes with the opening to the front. In terms of dimensions, the V6 version with 35 cm x 29 cm x 23 cm and a weight of 9 kilograms is still quite handy, while the V8 with 43 cm x 35 cm x 28 cm and 14 kilograms combat weight already leaves a quite powerful impression. Except for the points mentioned above, the construction of the two systems is identical.
The fact that, in addition to the woofer, the tweeter driver is now also made of aramid Kevlar, which has a strong sonic impact on the high-mid and high-frequency range, can be considered a major feature. Kevlar shines in the audio field, among other things, due to the fact that it is very light and very torsionally stiff and thus displays very good impulse behavior. Especially in the speed of a resting phase of the speaker, Kevlar is superior to many other materials in terms of inertia, but of course this is accompanied by a different basic sound of the system.
The corners of the cabinets were beveled in favor of phase fidelity in an MDF/aluminum construction on the front, a luminous KRK logo provides information about the operating status of the boxes. The speakers also come with a protective grille, which can be placed in front of the two speakers with a few simple steps if necessary. To protect the speakers from scratching the bottom side, EVA pads are mounted on the bottom side by means of 4 screws, which also allow a slight decoupling to the support surface (speaker stands / tabletop).
At the rear, the systems have a balanced TRS / XLR combo jack, along with ground lift and a selector switch, which can switch the input sensitivity optionally between -10 dB and +4 dB. Also the extensive setting options in terms of room sound adjustment with a total of 49 possibilities show unmistakably which clientele is to be addressed here. The filter settings are based on DSP technology, which can be updated via a micro USB port if necessary.
Practice
In neutral operation without any filter settings, the two KRK representatives quickly show their strengths. In terms of response, the Kevlar woofer truly sets standards, especially when it comes to synthetic sounds. Even with heavy bass thunderstorms, the signal remains very well locatable at high volumes and does not drown in the inertia of the woofer mass. The stereo image is balanced and very stable towards the sides in an optimal sitting position.
Also interesting is the fact how low the reproduction of the KRK V6S4 version already reaches down. The advertising-effective 40 Hz of the product sheet are also only touched here, but the range around 70 Hz is already very well performed here. In cooperation with the 12S woofer, a very adult reproduction should already be possible here. As expected, the KRK V8S4 version puts one more on top. The construction pushes here already very official, so that one can even think about omitting a woofer.
Due to the Kevlar tweeter, the mids are naturally very noticeable sonically. The impulse behavior is no longer quite as blatant as in the bass range with oscillating bellies in this frequency range, but the fast response allows for a clearly "harder" reproduction of the sound material. This is not to be taken as a judgement in this case, but the ear will need some time to become familiar with the Kevlar sound.
Conclusion
With the KRK V6S4 and KRK V8S4, the user gets a lot of quality for the money. An excellent impulse response, combined with a very good bass response allows a balanced work in almost all styles. Whether you like the typical sound of a KRK speaker, of course, everyone must decide for themselves, but if you get used to the sometimes harsh basic sound, you have a very good work tool at hand.

TEST: KRK Rokit 8
With the KRK Rokit RP8, the company, which belongs to Stanton Magnetics, launches a product line that should be particularly interesting for small budgets. The product line consisting of three different models (RP5, RP6, RP8), which is manufactured in China, is now already in its second generation and clearly stands out visually from its predecessors. Of course, the optical trademark of the company has remained, the bright yellow woofer made of fiberglass aramid, which is characterized by high strength at very low weight.
With a street price of just under 230 euros per speaker, the company has to face a large number of competitors who also have big names and want to penetrate the monitoring ranks of smaller budget studios with an inexpensive line. For the test we have the most powerful variant Rokit 8 with a, who would have expected it, 8 inch bass speaker.
Construction
A single KRK Rokit 8 speaker comes with a weight of 13.9 kilograms and the dimensions (HxWxD): 381 mm x 265 mm x 330 mm, which can still be handled well in practice, but requires a correspondingly load-bearing construction for wall mounting. In terms of cabinet shape, KRK also follows the general current trend away from fixed cubic basic shapes towards rounded, more stylish cabinets. In the case of the Rokit series, the fashionable adjustment is limited to the front of the housing, which in the form of an attached plastic panel accommodates the tweeter and woofer and forms the slot for the bass reflex port.
The reason for rounded cabinet shapes is not only due to a fashionable trend in the near field monitor sector. Rather, the goal is to minimize so-called edge reflections, which occur primarily in the high-frequency range. Another form of maintaining phase fidelity, an asymmetrical enclosure shape, was not used here.
Although the speakers are magnetically shielded, the KRK Rokit RP8 version is, in my opinion, overdimensioned for a direct placement at a computer workstation near the PC monitor, here the RP6 version, or better yet RP5 would be the better choice. The work surface should already have the standards of a medium control room to be able to use the performance of the speakers accordingly. However, since the bass reflex port radiates to the front, the speakers can be placed somewhat closer to a rear wall than is the case with a rear radiating version. Nevertheless, a small distance to the wall or even a corner placement has to be counteracted with corresponding reductions in the low frequency range.
In terms of speakers, the Prodipe TDC 8 is set up as a 2-way solution, which is expressed in the form of an 8-inch glass-aramid woofer, respectively 1-inch neodymium textile tweeter. According to factory specifications, the tweeter has a load of 20, the woofer over 70 watts, the whole at a frequency response of 45 - 20 kHz. As inputs XLR balanced, TSR balanced and RCA are available, whereby the tweeter range can be varied by -2dB, -1dB, 0dB, +1dB, the low frequency range by -2dB, -1dB, 0dB, +2dB by means of a rotary control. The system can be adjusted between -30 dB to +6 dB via a volume control. Finally, the power or IEC IEC connector and fuse on the back should be mentioned. The power consumption is specified with 160 watts.
Practice
The company KRK, which was founded in 1986 by Keith R. Klawitter, is generally associated with a basic sound standard, which in combination with the characteristic appearance enjoys great popularity in countless studios around the world. Aware of this, the experienced manufacturer will almost certainly not run the risk of jeopardizing its reputation with the Rokit Budget line. And truly, after activating the power switches, the very first sounds leave no doubts about the quality of the signal.
Sonically, the KRK Rokit 8 has an amazingly balanced midrange, which usually sags in the crossover frequency due to the basic construction in 2-way systems. Especially the notorious sound of a distorted guitar, which some competitors like to reproduce rather scratchy, respectively sawing, comes along comparatively balanced with this product. In the bass range, KRK fortunately avoids a too strong reproduction up to about 100 Hertz, with which one likes to try to gain the listener's attention, although due to the radiation of the reflective tunnel to the front, one cannot complain about a too low bass content. On the other hand, the speaker can be placed comparatively close to a reflective wall without falling prey to the notorious reflection boom.
In terms of high-frequency reproduction, the Soft Dome resolves unexpectedly high and displays above-average fine detail. Especially the decent treble range, which lacks any sharpness, pleases with a pleasant basic sound. However, what emerges as immensely important for the KRK Rokit 8 is a scrupulously accurate adherence to the stereo triangle, which is the basis of every good set-up position. Even slight deviations in the listening position result in a massive drop in the depth and resolution in the high frequency range.
Especially if the monitors are placed low, for example on the desktop of the PC, the quality of the vertical dispersion is massively reduced. Thus, if you work in a studio in pairs, you should possibly be prepared to sit behind each other and not next to each other, otherwise at least one, if not both users will approach a dead spot. However, those who don't leave the triangle will be spoiled in return with an unusually good sound in this price range, which is also characterized by a great flexibility in terms of music direction.
What is also very pleasant is the fast response of the system. The low weight of the woofer is immediately noticeable and provides the monitors with a high impulse fidelity even at higher listening volumes.
Conclusion
With the KRK Rokit 8 series, the American manufacturer manages to transport a lot of the sound culture of its forefathers into the budget line. As with the more expensive lines such as Expose, V or RP, the Rokit series also uses a low / midrange construction of lightweight but high-strength composite membranes, in this case aramid, which sustainably shapes the sound through high impulse fidelity and good spatial resolution.
With an affordable price and good detail solutions, the Rokit series is a real recommendation in this price range.

TEST: KRK GoAux 4
Whether it's coffee, pizza or whatever unusual products, many things are now "To Go", i.e. "to take away". Articles, which are otherwise stationary fed or used, can now also be packed and used where you are. Well then, why not transfer the same to the audio sector, KRK Systems will have asked itself and therefore created a very portable speaker called KRK GoAux 4. Let's see what demands the company, which now belongs to the guitar giant Gibson, will meet with these very special speakers.
The construction of the KRK GoAux 4
"No, what are the cuddly", so or so similar one or the other user will already react to the really very portable near field monitors, similar statements might have already taken owners of Havanese, Chihuahuas or Yorkshire Terriers. In fact, the speakers, which are made of plastic in China, can easily pass for PC speakers with their dimensions of (H x W x D): 205 mm x 136 mm x 140 mm and should also fit on a very small table. In terms of transportability, such dimensions are hard to beat.
But why should you call transportable speakers your own at all, especially since you have a serious competitor in the field of small luggage with high-quality headphones? Well, if we look back to the heyday of recording studio culture, there were not only real "rock stars" on and backstage, but there were also various engineers who had a legendary reputation especially in the mixing field and were hired just like studio musicians for various sessions. Analog recording studios were giants of technology and it was impossible to be able to mix your recordings in every loo as you do today. So it was common for the mixing engineer to get on the next plane and carry in his luggage, besides his most important outgear like compressors, EQs, etc., if possible a couple of portable nearfield monitors to which he was tuned in to better judge the final result.
Since today everyone can set up his home recording studio in any room of his home, this area is reserved only for the Champions League of artists, where studio stays can be deducted as advertising costs and money ultimately does not matter. However, near-field monitors still offer a different listening impression than headphones, even though the physical conditions could not be more diametrically opposed, especially as far as the bass range is concerned.
Already during the unpacking of the KRK GoAux 4, one notices the different weights of the two speakers, which has a very simple reason. The housing of the left speaker contains the entire electronics of the system, the power supply and the power amplifier, which brings out of the 4" woofer (33 watts) and the 1" tweeter (17 watts) nevertheless stately 50 watts per monitor, whereby I am very sure, we are talking about peak power, which probably then depicts between 15 - 20 watts RMS. The right monitor is only supplied with a supplied speaker cable and is basically a passive speaker. Of course, this principle is not completely new, because who does not know the legendary JBL Control One, which was also available in an active version many decades ago and whose principle is identical to the KRK GoAux 4. P.S. Who has the chance to get hold of old Control One, whose membrane has not yet decayed, absolutely buy, the new ones do not even have the same sound quality.
Both speakers of the KRK GoAux 4 are protected against external influences by black grilles, and the cone of the woofer was of course colored in the typical KRK yellow. According to the manufacturer, the KRK GoAux 4 offer a frequency response at -3 dBSPL from 60 - 20,000 Hz and at -10 dBSPL from 55 - 22,000 Hz at a maximum level of 98.5 dB, although especially the specifications in the bass range should be considered with the necessary abstraction. In order to give the small enclosures a bit more bass volume, both speakers have a bass reflex port on the back at the top, which radiates to the rear.
The accessories of the KRK GoAux 4
It's rare enough that nearfield monitors get a separate paragraph in the accessories section, but what KRK includes here is truly remarkable. For one thing, there's the padded, durable carrying case in which the two speakers rest in two separate compartments. The middle section, also padded, is occupied by two speaker stands onto which the monitors can be fixed by means of two supplied screw knobs, and then their angle of inclination can be changed. Two pockets on the side and another in the lid contain a Quick Start Manual in seven languages, a power cord (the transformer is inside the cabinet!), the speaker cable for the right speaker and, as a special feature, a special measuring microphone, which, in conjunction with appropriate control electronics, allows a rudimentary calibration of the monitoring situation in the bass range.
Connections and control options
Except for the master volume knob on the front, all control options are located on the back of the left speaker. In addition to a mini jack AUX In, a USB In and two TRS jacks, the system can also be supplied with signals via Bluetooth. Four small pushbuttons with the corresponding LEDs control Bluetooth pairing, activation of the ARC calibration process and a two-band tone control consisting of treble and bass. Depending on the brightness of the respective LED, the bands offer a 3 dB cut, a flat setting or a 2 dB boost.
Furthermore, the socket for the four-pole speaker cable is located on the back, which can only be removed from the socket with a bit of fiddling once it has sunk into the housing. Well, for an official jack solution it gets a bit tight with the space available on the back of the active box. Otherwise, there is still the On / Off switch and a two-pin power plug socket, since due to the plastic housing the cold device solution is not necessary. As already mentioned, here again an extra point for the internal power supply, I'm sure an external solution would have been cheaper, but also much more annoying.
The KRK GoAux 4 in practice
The first sound impression of the KRK GoAux 4 reminds me of a high-end boombox, which is not surprising due to the dimensions, but with a very high approach to sound quality. KRK has actually managed to transport a large part of the well-known KRK sound with its open, well resolved sound image actually into these tiny speakers. The midrange is very dominant, is nicely transparent and reproduces classic midrange instruments like guitar and vocals well. The high-frequency range also knows how to please, especially when you initiate a decent boost using the push buttons on the back.
Speaking of push buttons, of course you have to make compromises with these cabinet dimensions, so you can still accept the rear access with the "Walk Behind-Push-Walk In Front-Listen-Repeat" workflow. However, the "LED light levels" tone control is a bit confusing and not really easy to read, so you should take your time with the tone control management.
Regarding the bass reproduction, every user will be aware that a 4-inch speaker cannot physically produce deep bass and certainly cannot replace an official studio monitor, which is not the approach of the KRK GoAux 4. I was all the more surprised that at least in the three-digit Hertz range, the bass reproduction was unusually tight and at least the "audible" bass range appeared well perceptible. The bass response improved even more after I had calibrated the speakers via the measuring microphone. By means of two measurement passes, the electronics reduced several booming frequencies of the room and boosted the lower bass ranges, which was reflected in a stable and pleasant bass sound.
In summary, the KRK GoAux 4 offer a much more grown-up sound than the first optical impression would suggest. The concept is coherent, the dimensions tiny, the sound good and the accessories excellent. A well-rounded thing and much more than a toy.
Conclusion
With the KRK GoAux 4, the company carries a tiny but surprisingly good-sounding near-field monitor system in its portfolio. The very transportable speakers offer much more sonically than one would give them credit for at first glance, and even manage to deliver a surprisingly round bass sound considering a 4-inch bass speaker thanks to the included calibration microphone.
Anyone who prefers to do mobile recording or editing work on the road with monitors rather than headphones should definitely give the monitors a try.

TEST: KRK 852
Nearfield monitors without subwoofers are a tricky subject. Only a few systems are really able to generate a balanced sound, especially below 80 Hz, and if this should be the case, you are almost in the midfield range with corresponding 10-inch woofers. Since in the course of music production development only a few professional studios still have correspondingly large control rooms, subwoofers belong to the basic equipment of every studio, especially in the budget and home recording area. In order to provide even the ambitious newcomer with a controlled bass range for little money, the KRK company has launched an S-series of three different woofers, of which the smallest version, the KRK 8S2, is available for us to test.
The construction of the KRK 8S2
The KRK 8S2 is a further development of the KRK S-series, which should be located in particular in the improved frequency response. Already the first impression of the KRK 8S2 lets an association to the KRK sales hit Rokit arise, caused by the housing design and the yellow colored 8" glass-aramid fabric woofer. With dimensions (H x W x D) 362 mm x 339 mm x 294 mm and a weight of 11.8 kg, there are by all means even smaller representatives in the 8-inch and less range, such as the Eve Audio TS 107 ( https://www.amazona.de/test-eve-audio-ts107-subwoofer/ ), but the outer presentation lends itself especially to control rooms with severely limited dimensions.
While the big brothers 12S2 (12-inch woofer) come along with 220 watts, or 10S2 (10-inch woofer) with 160 watts "continuous load", the KRK 8S2 must be content with a power of 109 watts from a Class D power amplifier. This should be quite sufficient for small control rooms, especially since the woofer was not designed to acoustically illuminate a larger control room accordingly impulsive. The frequency response of the woofer, on the other hand, arouses curiosity, especially since the KRK 8S2 covers a range of 35 - 133 Hz according to the manufacturer. For an 8-incher just over 100 watts, this is a very ambitious undertaking; even a clean low end of 40 Hz would represent a decent performance. The maximum level is stated at 112.8 dB.
The Chinese-made cabinet is made from a combination of plastic in the front and MDF panels in the middle, and is impeccably finished. The appearance is visually appealing and fits in with the various KRK product lines. Like many other products, which have also been provided with a smooth and matte surface, the KRK 8S2 tends to accumulate fingerprints, so if the woofer, which can be seen more or less as a cube, is moved more often, always keep cleaning cloth within reach. The speaker is protected from external influences by a very massive front grille, whereby the bass reflex port is located below the grille, which radiates to the front. As we know, however, this point plays a rather subordinate role, since the bass radiates circularly from the speaker into the room anyway. The case sits on a continuous rubber plate, which was glued to the bottom of the case.
If you turn to the back of the case, you'll find all the control and adjustment elements there. Already at first sight one recognizes that the KRK 8S2 has an extensive arsenal of control and input possibilities for a product of its price class. First of all, it should be noted that in addition to the balanced XLR and TRS connectors, the product also has the unbalanced RCA connector pair, which is important for the consumer sector, and this both as input and output.
Below the 12 sockets in total, there is a connection socket that can be used to deactivate the subwoofer by means of a jack foot switch. The right area of the rear panel is rounded off by an operation LED, the On / Off switch and the power plug socket. On the left side, we are greeted by 2 controls and 6 switches, which have the following functions from top to bottom:
Volume control: controls the overall volume of the woofer
Crossover: lets you choose between 4 different frequencies (70 Hz, 80 Hz, 90 Hz, 100 Hz)
Input Sensitivity: input sensitivity of the woofer, can be selected between Normal and High (recommended for home electronics)
Polarity: Phase switch, to counteract any counter-phase cancellations that may occur
Standby: switches the woofer into standby mode after 30 minutes of inactivity for power saving reasons
Ground Lift: prevents ground hum loops
The KRK 8S2's volume control is also finely dialed, making it easy to fine-tune the woofer. A 0 dB or similar. One looks in vain, here it is only the woofer between "Min." and "Max." to add by ear. On the other hand, you have to use a lot of force when selecting the crossover frequency to get it to switch, but the resistance is reduced after turning the knob a few times.
The KRK 8S2 in practice
If we switch on the woofer, the two-color LED on the back shows us an orange signal, which changes to green when the level is applied. On the front, a white LED shows us the activation of the system. As test material I have taken various reference recordings, reference mixes, various individual instruments and some productions, which I have created myself, to get as comprehensive a sound impression as possible.
First of all, it is necessary to find the optimal crossover frequency depending on the satellites, which turned out to be not so easy. In my studio 2 are 2 pcs Eve Audio SC 204, which are normally protected with an Eve Audio TS 107 downwards. To the same the KRK 8S2 was connected to take over the function of the TS 107. In order to take over the sound material below the comparatively small 4-inch "woofers" of the Eve Audio satellites as comprehensively as possible, the 100 Hz setting left the best impression, but the woofer tended to boom quite quickly in this setting. Even changing the placement, or activating the phase inversion could not prevent this.
This changed immediately when I set the crossover frequency to 90 Hz, better yet to 80 Hz. Here the woofer rounded off very nicely downwards, but left a frequency hole in the area of the just mentioned bass range. This could be compensated by taking the satellites a bit more into the "bass duty", which could be implemented very well with the Eve Audio. The result was an all-around satisfactory frequency coverage down to the low bass range.
Sonically, the KRK 8S2 is comparatively soft. The speaker never seemed overpowered, even though I only used moderate volumes, as is usually the case in a Studio 2. What gives me a little food for thought is the tendency to boom in small rooms. The woofer does its job flawlessly, but there is a certain point in volume where the KRK 8S2, depending on the room dimensions and its geometry, starts to give in to a subtle drone. Skillful positioning can push this effect back, but who in a small control room has the opportunity to experiment spatially with the placement of a woofer.
As expected, the system does not like placement close to a wall or below the desk, both of which only lead to the aforementioned undifferentiated reproduction. If, on the other hand, the KRK 8S2 is placed freely in the room and the corresponding acoustic construction has been carried out, the system is convincing all the way, especially if the retail price is taken into consideration. The eight-incher also holds its own very bravely as far as the "real" low bass range is concerned. Even if the construction can't move the corresponding amount of air of a 10 or 12 inch speaker, the speaker manages in cooperation with the cabinet to convey a good acoustic overview of everything that's going on in the bass range and possibly spoils the clean bass reproduction over a large monitor or in the live area.
In summary, the KRK 8S2 can be given a good report card. The subwoofer does what it is supposed to do and will also be a favorable addition, especially with inexpensive satellites, to prevent bass-heavy mixes.
Conclusion
With the KRK 8S2, the manufacturer offers an inexpensive subwoofer that offers a lot of quality for the money. The setting options are extensive, the basic sound is good, and the workmanship is impeccable. If you are looking for a budget and home recording supplement for your near-field monitors for better control in the bass range for little money, you should definitely test the woofer.

Nearfield monitors are critical tools in professional audio production environments, designed to provide accurate and detailed sound reproduction. These specialized speakers, also known as studio monitors, are optimized for close-range listening and are widely used in recording studios, mixing rooms, and post-production facilities. This report aims to provide an in-depth overview of nearfield monitors, including their purpose, design characteristics, technological advancements, and their significance in professional audio monitoring.
Purpose and Design Characteristics: The primary purpose of nearfield monitors is to provide an accurate representation of audio content. They are specifically designed for nearfield listening, where the listener sits in close proximity to the speakers, typically within a few feet. Unlike consumer-grade speakers, nearfield monitors prioritize precision and transparency over coloration and exaggerated bass response.
Nearfield monitors are typically active speakers, meaning they have built-in amplification, allowing for better control and integration of the speaker components. They often feature a two-way or three-way design, comprising a woofer for low-frequency reproduction and a tweeter for high-frequency reproduction. Some models also incorporate a dedicated mid-range driver for enhanced clarity in the critical mid-frequency range.
To minimize unwanted resonances and improve accuracy, nearfield monitors employ a variety of design elements, such as acoustic damping materials, optimized cabinet shapes, and precision-tuned crossovers. These features contribute to a more linear frequency response, reduced phase distortion, and improved imaging capabilities.
Technological Advancements: Nearfield monitors have benefited from technological advancements, allowing for enhanced performance and accuracy. Some notable advancements include:
Driver Technology: Manufacturers have developed specialized drivers using advanced materials and designs. This includes using lightweight yet rigid materials for the diaphragms to reduce distortion and improve transient response.

This allows for precise control over the speaker's frequency response, equalization, and room correction, resulting in more accurate sound reproduction.
c) Waveguide and Directivity Control: Advanced waveguide designs and directivity control technologies help optimize the dispersion of sound, resulting in improved stereo imaging and a more consistent listening experience within the sweet spot.
d) Room Calibration: Some nearfield monitors now offer room calibration features, either through dedicated hardware or software. This enables users to compensate for room anomalies and achieve more accurate monitoring, regardless of the acoustic characteristics of the listening environment.
Significance in Professional Audio Monitoring: Nearfield monitors play a crucial role in professional audio monitoring, offering several key benefits:
Accuracy and Transparency: Nearfield monitors are designed to provide a faithful representation of the audio content, allowing engineers and producers to make precise judgments regarding the mix, tonal balance, and spatial placement of elements within the soundstage.
b) Critical Listening Environment: Nearfield monitoring setups create an optimized listening environment where the sound arrives directly without significant reflections or room coloration. This helps engineers detect subtle details, stereo imaging, and transient responses accurately.
c) Consistency: Nearfield monitors are designed to produce consistent and reliable results across different listening environments. This allows engineers to create mixes that translate well to various playback systems, such as consumer speakers, headphones, and car audio systems.
d) Workflow Efficiency: The detailed and accurate sound reproduction of nearfield monitors speeds up the mixing and mastering process. Engineers can make informed decisions quickly, leading to efficient workflows and high-quality results.
Considerations and Best Practices: To maximize the effectiveness of nearfield monitors, certain considerations and best practices should be followed:
Room Acoustics: Ensuring a well-treated and acoustically controlled listening environment minimizes the impact of room resonances and reflections, optimizing the accuracy of monitoring.
b) Speaker Placement: Positioning the nearfield monitors at an appropriate height and angle, along with proper listener positioning, creates an optimal listening triangle and improves stereo imaging.
c) Calibration and Positioning: Utilizing room correction systems or manual calibration tools can further refine the frequency response and compensate for room anomalies.
d) Reference Listening: Regularly referencing mixes on other audio systems, such as headphones or secondary monitors, helps ensure the mix translates well across different playback environments.
Conclusion:
Nearfield monitors are essential tools in professional audio production, providing accurate and detailed sound reproduction in critical listening environments. With advancements in driver technology, amplification, DSP, and room calibration features, nearfield monitors continue to evolve, enabling engineers and producers to create high-quality mixes that translate well across various playback systems. By prioritizing accuracy and transparency, nearfield monitors have become indispensable for professionals seeking precise control over their audio productions.
TEST: Korg Pandora PX50
At that time still divided into four different basic units, the successor, the PX4, merged the instrument groups bass and guitar, which is also continued in the Pandora PX5D that I have for testing. Well then, let's see what the little jack-of-all-trades for the vest pocket has to offer and if you can find your way through the menu navigation, which will be a real challenge with the manifold collection of possibilities in the smallest space.
Design
In principle, the PX5D is a combination multi-effects unit with a combined amp/speaker modeling concept, which in 2010 is also happy to take on more advanced functions such as a USB interface, which one would not have expected from the tiny device at first glance. Despite the production in the low-wage country China, Korg has almost doubled the price of the product, which is now made of aluminum, to almost 300 Euros compared to its plastic predecessor, which can only be justified to the user by a significant increase in practicality. In any case, the flat case already exudes much more esprit visually than its plastic predecessor. With dimensions of 118 x 20 x 75 mm, the product is also very handy.
Powered by two AA batteries, the product is supposed to last seven hours according to factory specifications, which can be called adequate. Unfortunately, a 4.5 volt power supply is not included with the product and must be purchased separately for just under 30 euros (for example, the Korg NT-4). Optionally, the device can also be operated via the USB port in terms of voltage. However, Korg adds other accessories to the Pandora, such as a USB cable for the direct connection to the home PC, an adapter cable with which 2 footswitches can be configured for start/stop and another function, and a CD-ROM containing the recording software Ableton Live Lite 6. However, the product is also recognized by standard recording tools such as Garageband, Cubase and Logic.
With 180 effect and amp models with a storage capacity of 200 programs (100 presets / 100 users), Korg rides a rich program in terms of presets. In addition, the device has 128 rhythm patterns with a total of 744 variations in the various musical styles. Also built in is a phrase trainer, which can store up to 80 seconds of audio material, a tuner with mute function and a transpose function for the sampled audio material.
Practice
So, what does the PX5D do in the life of a strung musician? Quite simply, it makes practicing easier or it supports the creative process! The same constant should always be kept in mind when examining the product. The world is full of contemporaries who, as soon as they hear a technical term, raise their expectations immeasurably and then have to be brought back down to earth by third parties. A multifunctional device is no substitute for a recording process where the interface alone costs well over five times as much.
Even though the product has 18 virtual guitar amp simulations, 10 bass emulations and 6 synth sounds, all of which offer a usable basic sound, professional productions cannot be implemented with the little box (unless you consider the last Metallica record to be a professional production). On the other hand, the handling of the Pandora is pleasantly problem-free after a short training period and quickly brings usable results in terms of songwriting and pre-productions.
Sonically, the factory sounds can hold their own well within their field of application, even if their virtual birth hours are always perceptible for fine ears. As almost always, clean sounds can convince better than their distorted colleagues, which can not be compensated even by the strong use from the effects battery. But hey, I myself resorted to purely virtual sound generation for pre-production during songwriting for the new GRAVE DIGGER album, not without using classic miking for the final guitars, of course.
In terms of connections, the Pandora has standard jack sockets for input and output respectively, mini jack for feeding an audio signal and applying the footswitches. Output also provides the option of connecting headphones. The internal phrase sampler has a good recording quality, but only records the recorded material in mono. You can decide for yourself whether you want to feed an external signal via aux-in or use the internal rhythm guide.
With the help of the included recording software, you can record the played or sampled material on your PC on up to two tracks and edit it further. If a driver is not on the included CD-ROM, it can be downloaded from www.korg.com.
Conclusion
Smaller and smaller, finer and finer. It's remarkable what designers can fit into a very small space these days thanks to microtechnology. With the Pandora PX5D, Korg has a small, thoroughly decent-sounding effects unit with amp/speaker emulation on the market, which delivers good and practical settings in many situations.
If it's a matter of comparatively uncomplicated recording of one's own compositions, quick archiving of a fleeting idea or controlled practicing, the PX5D manages to do justice to its conception in a surprisingly uncomplicated way. Nevertheless, you first have to get used to the somewhat unfamiliar menu navigation of the product, without a users manual nothing works here.
Once you have overcome this hurdle, the PX5D turns out to be a small helper, which provides good services in many situations and finds a place in almost every pocket. It's just a pity that Korg doesn't include a power supply with the product, especially since 4.5 volts is only a common value in the multi-voltage wall wart range, while 90 percent of all power supplies romp around in the 9 volt range. Sometimes I can't get rid of the impression that they simply want to sell an additional power supply over the unusual value….

TEST: Koch Amps Little Gristle
The paths to successful brand placement always seem inscrutable. There are companies that have been shining with outstanding products for decades and still have the touch of an "insider tip" attached to them. The company Koch Amps from the Netherlands must undoubtedly be counted in this category. On the market for almost 34 years and blessed with numerous high-end amplifiers in the areas of blues, rock and hard_n_heavy in the portfolio, the Dutchmen convince almost every guitarist who has ever connected his instrument to the products Twintone, Powertone, Classictone or Studiotone. With the signature amp "The Greg" for exceptional guitarist Greg Koch (not related by marriage or related to company founder Dolf Koch), the company gained a greater reach among musicians, but still comparatively few guitarists know that, for example, the Powertone Head can compete with the best hard'n'heavy heads in terms of sound. The fact that the Koch company has always had a strong connection to puristic all-tube amps can be seen not least in the company's latest offshoot, the Koch Amps Little Gristle, which draws attention to itself in several respects.
The construction of the Koch Amps Little Gristle
Anyone who takes a quick look at the "little cartilage" is undoubtedly reminded of the big American "F", which is the only company in the world to have achieved world fame in both instrument and amplifier construction. It's really hard to launch a tweed covered cabinet and not let the Bassman, Twin, Deluxe, Champ or other products roll by in your mind's eye. In contrast to the Fender protagonists, the cover fabric of the Koch Amp Little Gristle looks a bit shinier, as if it were covered with a subtle protective layer. This fabric is probably a little easier to clean than the Fender fabric, which absorbs any form of dirt.
A look at the control panel, which was installed in the "more comfortable" front view, clearly shows which customer group the Koch Amps Little Gristle was designed for. Just 4 controllers control the all-tube combo, which comes up with only one 12AX7 preamp tube and a single-ended EL34 as a power tube, with one controller already controlling the internally installed reverb spiral. You can hardly design an amp more puristically, Gristle (preamplifier), Tone (tone control), More (power amplifier), done. The preamp can be boosted a little via a mini switch, but that's it with the control options. A triode / pentode circuit can be used to tickle 12 or 4 watts out of the amp, which, however, generates significantly more noise than the numbers suggest. Don't forget, a 12 watt amp is only half as loud as a 120 watt amp! Especially in 12 watt operation, the maximum volume is easily sufficient to fill a typical club stage with sound and to keep up with a moderately playing drummer in terms of dynamics.
If you want to operate the amp without speakers, you also have the option of deactivating the internally built-in 8 ohm / 12 inch speaker from our own production when the speaker cable is pulled, protecting the amp from underload via an internal power soak and using a speaker simulation. In terms of weight, the combo is comparatively light for an all-tube amp. With dimensions of 54 cm x 27.5 cm x 46 cm (W x D x H) and a weight of 16.25 kg, the combo is comparatively easy to transport. The massive carrying handle does its part to enable the combo to be lifted without major problems. Time will tell to what extent the tweed fabric can withstand normal everyday transport, but I can only recommend getting at least a padded cover for the combo. The ambitious musician will anyway buy a hood case for the amp, in which a tube amp is still best to transport.
In terms of workmanship, the Koch Amps Little Gristle is at the highest level. Nothing that was done half-heartedly in any way, or eliminated for cost reasons, even though it was needed for optimal performance. The entire concept is coherent and picks up the intended target group where it would like to be picked up. But how exactly does the amp do that?
The Chef Amps Little Gristle in action
As I said, anyone who offers a user interface like that of the Koch Amps Little Gristle assumes that the artist knows what to expect. So if you wanted to squeeze the area of application of the Koch Amps Little Gristle into one style, the bottom line would be the word "Blues". Why is this the case, or what makes a good blues amp?
Well, several components are responsible for a good blues tone, apart from the musician's technical skills. On the one hand, there is no need for a high gain structure, which is why the Koch Amps Little Gristle only comes with a single preamp tube. Gain reserves that are too high compress the sound too much and, with a single-channel device, result in a sound that is too one-dimensional, which cannot necessarily be controlled with the volume control on the guitar. Here it is better to use your favorite overdrive pedal, which will very likely harmonize very well with the Koch Amps Little Gristle. The spartan design and the all-tube construction offer a very good basis for booster and overdrive pedals of all kinds.
Second, a good blues amp requires the highest possible dynamics in the amp, preferably paired with a slight crunch in the peak area, which can then be adjusted down to clean with the volume control on the guitar. This is where the Koch Amps Little Gristle scores particularly well, especially when you have found your personal optimum match between the preamp and power amp. It's really amazing what you can do with just these two controls and how much this tuning affects the sound. If you set this amp according to the motto preamp > find gain factor > power amp > find final volume, as is often the case with high gain amps, you lose a lot of the sound quality that the amp offers.
My personal approach was actually the opposite of the global approach, i.e. I had my maximum sonic yield by turning the power amp to full stop, choosing a middle position with the tone control and choosing the final volume with the Gristle control. It's really incredible how dynamically the Class A works in this setting, especially if you choose a dynamic playing style and know how to use the guitar's volume control. The result was an almost soft saturation with a greatly increased sustain, which even moved the neck pickup of a Strat to a greatly extended clean tone without losing dynamics.
The third characteristic of a good blues tone is the direct and unembellished interaction with the guitar and its characteristics. Of course, different instruments also sound different when connected to the amplifier in terms of overall sound, but if you have the opportunity to test an amp like the Koch Amps Little Gristle in a direct A/B comparison with the clean channel of a multi-channel all-tube combo, you should definitely do so do once. Rarely is it possible to perceive the diametrically opposed tonal alignment of woods, scales and hardware, for example between a Strat and a Paula, as intensely as with this amp perceive on the Koch Amps Little Gristle.
If one can perceive a disadvantage of this direct and unadulterated sound at all, then it is the also unembellished reproduction of all playing errors and imperfections of the artist, which are otherwise often hidden in the preamp gain. If the sound drowns you here, no more stacking will help you bring the selected note home with hanging and choking. But woe betide you hit the tone with full power, then the amp develops a penetrating power like a steam hammer.
Conclusion
With the Koch Amps Little Gristle, the Dutch company has a very high-quality single-channel amplifier in its range, which convinces in many respects. The puristic all-tube amp has all the attributes you could wish for from a real blues amp and pushes them to the limit. High dynamics and a very large interaction between instrument and amplifier characterize the sound culture of the combo and thus enable a very direct playing feeling for the musician.
If you are looking for a high-quality single-channel combo, you should definitely try the Koch Amps Little Gristle.

TEST: Koch Amps JUP45-H + KCC112
You know what I really like about product development in amplifier technology in recent years? The softening of the individual camps, which used to be characterized by bitter trench warfare, or in other words, a Dutch head like the Koch JUP45-H plus the matching box KCC112-GS60 would have caused a few decades ago still disbelieving head shaking. Why, some of you might ask.
Well, the hybrid technology used at that time was still in its infancy and provided more than half-baked results. The different transistor and tube elements were often combined in the wrong order and caused a scratchy distortion with a transistor preamp, combined with a lead-heavy tube power amp, which in 212 combo design often scratched at the 40 kilogram mark. Terrible!
It seemed to make much more sense to reverse the construction methods, since this way one already had the much warmer sounding distortion of a 12AX7. However one would have saved with a pure transistor output stage each quantity of weight, however in the same breath some Saturisation of the achievement glass shovel destroyed. What to do said Zeus. Well, as with the Valvetronix series from Vox, Koch takes a single ended power amp tube in the form of a 12AX7, uses its sound characteristics and hangs a MOS-FET power amp behind it to be able to produce enough power.
To put it bluntly, we are dealing with a very quiet all-tube amplifier, which is blown up to 50 watts via a transistor power amplifier, depending on the impedance of the speakers. The whole thing, however, with a comparatively low weight and the regular replacement of the power tubes is also saved. We are curious about that.
Head
The Koch JUP45-H is a three-channel top with the dimensions (WxHxD): 54 x 27.5 x 23.2 cm, whereby the three channels share a three-band tone control. The same tone control can be varied in the center frequencies via a Contour switch. One channel each ("Cool" - clean channel, "Hot" - lead channel) have a separate gain and volume control, whereby the lead channel can be set a little hotter in the gain via a boost switch.
In addition to a reverb control, which emulates a reverb spiral on a digital level, there is also a so-called "dimmer" control in the master area, which controls the final volume of the head. Koch Amps advertises with the description that due to the patented ATR circuit you can achieve a final stage saturation at any volume level.
Visually, the Koch JUP45-H presents itself in a very nice vintage green, which also features a matching brown faux leather handle. The slightly yellowed-looking knobs, which have also been trimmed to look old, can be read well even from a comparatively long distance. 4 steel corners provide the necessary protection during transport, four strong rubber feet provide the necessary stability.
On the back, a massive perforated plate prevents unauthorized objects or incompetent fingers from entering the amp's inner workings. They wouldn't be able to do much damage, though, since apart from a transformer and the two tubes, nothing sticks out of the amp's electronic inner workings. Anyway, one gets the impression that the dimensions of the amp are more due to the admittedly very pretty optical concept than they would be a spatial necessity. The actual components would only take up about half of the available space.
In terms of connections, the Koch JUP45-H has a serial FX loop, 2 speaker outputs, which can manage all common impedances from 4 to 16 ohms, a frequency-corrected output for recording purposes and a connection for the included, very massive 2-way footswitch. If necessary, the channels can also be switched manually by means of a switch here. Koch has built a very nice variation regarding the footswitch. By means of a mini switch you can set whether the second switch should activate the boost function or the reverb unit. Finally, on the left side, the mains plug and a microfuse, done!
In terms of volume, the power output decreases with the impedance of the connected speaker, as is usual with all transistor power amps. If 50 watts can still be generated at 4 ohms or 2x8 ohms, this drops to 45 watts at 8 or 2x16 ohms and drops further to 35 watts at 16 ohms. With a tube power amplifier this is compensated by different taps on the transformer, in addition, a tube power amplifier is short-circuit-proof, however, a transistor power amplifier is protected against no-load operation without load resistor. You can't have everything.
Cabinet
As a suitable addition in terms of loudspeakers, the Koch JUP45-H was accompanied by the Koch KCC112-GS60 speaker cabinet, which has the impedance of 8 ohms that is often used for small cabinets. It is a cabinet that comes with a bass reflex port in the form of a slot under the front cover and has a 12-inch speaker that can handle 90 watts RMS. Visually, the cabinet was also given a green cloth with silver / black front cover plus a brown leatherette handle. Very nice. Eight steel corners and four strong rubber feet complete the overall picture.
Practice
Anyone who has kept an eye on the Dutch company in the past will have quickly noticed that the strengths of the various Koch Heads and Combos are to be found in rock and blues. Not that products like the Powertone or Supernova can't satisfy high-gain fanatics, but in the final analysis Koch always prioritizes its tuning a tad more on the ultimate tone of its amps than on the degree of half-wave cut. For maximum interaction with the artist, only all-tube amps from the halls of Holland's most successful amp manufacturer have found their way to the customer.
Aware of this, you have to launch a very sophisticated product in order not to alienate your core clientele and still reach new groups of buyers with the weight, price and maintenance advantages of a hybrid amp. To say it in advance, Koch has done everything right. This is immediately noticeable in the basic sound of the "Cool" channel. The sound is warm and clean, with the emphasis on the adjective warm. Ultra-clean, sterile sounds are fortunately not to be elicited from the Koch JUP45-H, there always remains the touch of ear candy.
However, you can also elicit very nice crunch sounds from the Cool Channel with appropriate gain application. Here it is truly worthwhile to follow his play instinct a little and to act with gain and volume accordingly. In the Hot Channel, the distortion level increases accordingly and delivers from light crunches to a proper rock board all the sounds that the standard gain program so offers. The sound remains nicely transparent even in powerful regions and sprays just the right portion of "Everybodys Darling", paired with enough independence.
The Boost function actually activates a booster that doesn't change much more in the sound character and only increases the gain portion for wonderfully standing, long decaying tones. "Yeah, ok, that's all well and good", I can already hear the first people saying, "but what's special about it now"? Well, for one thing, we're talking about a hybrid amp with European manufacturing under 600 euros, and most importantly, the Koch JUP45-H actually manages to generate that sound at ALL volumes.
The dimmer control bears its name truly not without reason. The entire sound spectrum can be transported with this control in all volume ranges, from the popular bedroom amp up to the big stage. You can drive the power amp very nicely into saturation and still reduce the volume to a minimum. Great!
Conclusion
With the Koch JUP45-H and the matching KCC112-GS60 speaker, the Dutch company has an excellent combination on offer. For just under 1,000 euros retail price, you get a very good, vintage-oriented head/cabinet solution that manages to transport its excellent basic sound into all volume ranges.
The annoying "quiet-sounding-it-doesn't" can be confidently left at the checkroom. A blessing in small clubs for the musicians as well as for the FOH and the audience!
Absolutely test!
