TEST: Kustom KU 12 J

Creedence Clearwater Revival. Logically, everyone knows them. No one, regardless of age, gender or social background, who has not heard at least one song of the band around the brilliant songwriter and singer John Fogerty on the radio or as a soundtrack in a Hollywood production.

The circle of people who should have seen the band live once, on the other hand, is much more manageable. Thanks to YouTube, however, one can compensate for the flaw of late birth and will find a truly unique guitar and bass backline in the band's old videos. If you look closely, you'll see heads and cabinets wrapped in an eye-catching "faux leather foam plush application," THE visual eye-catcher from the Kustom company.

The fusion of amp technology and HotRod outfit was started in the mid-sixties by company founder Bud Ross and was the absolute standout in terms of looks.

For many years I heard nothing from the company, until it suddenly presented itself again in the spotlight with a completely revised product range. For the test I have an inexpensive combo, the 12 Gauge J, a practice amplifier, which can come up with a few interesting features. As with almost all items in this price segment and also more and more in the upper middle class, so also here, "Designed In USA" - "Made In China"..............


Construction:

The 12 Gauge J is a fairly handy amp (461 mm width - 432 mm height - 254 mm depth) with a weight of 11.9 kg. It has an output volume of 16 watts, which sounds quite moderate at first, but in the course of the test turned out to be quite serious final volume.

The first impression after unpacking the device is quite positive, the amp makes a neatly processed impression and comes up with a few visually appealing details. The imitation leather used seems resistant, and 8 plastic corners also protect against knocks on the edges.

Only the plastic carrying handle exhales very strongly, within a short time the whole room smells of solvents or plasticizers. Even after 2 weeks of testing, the hands still smell very strong when you have transported the amplifier. The amplifier unit is accessible from the top, similar to many combos from the sixties.

By the way, who knows why almost all combos from that era made their amplifier unit accessible from the top and the labeling could only be read from the back?.....Well, at that time, due to the lack of powerful P.A. sound reinforcement as well as professional microphones, one stood behind(!) the combo on stage. The main sound level went into the audience, the own monitoring was taken over by the combo open to the back. Finished! Nix 6 monitor ways with separate stage mix and alone 4 channels with the F.O.H. only for a guitar occupy, those were the days, my friend! ;-)

One of the main problems with practice amps is usually the speaker size of the combo. If you don't try to get to grips with the combos, which are usually equipped with 10", 8" or even 6.5" speakers, with emulation solutions in the timbre, small speakers are usually annoying, especially in the distorted range, due to their design, with an overemphasis of the highs and a harsh, respectively edgy sound.

To counter this problem, the company Kustom has given the 12 Gauge, as the name suggests, a 12" speaker, a rather unusual feature in this price range. The brand is an in-house manufactured 8 ohm speaker, also made in China.

The speaker is mounted on the back and is protected from the front by a soft covering fabric against external influences. A visual parallel to Marshall's twisted paper covering solution is certainly recognizable, but Kustom has decided to use plastic.

A flexible, soft speaker protection has the advantage over a rigid grille that it absorbs light to medium shocks and then returns to its original position. A rigid grille already has dents here or is at least scratched. Only with a very strong impact against the speaker can the grille show its strengths, because in this case the soft covering material would tear.

The Gauge 12 has a two-channel design. Both channels share a three-band tone control. While the clean channel only has a volume control, the lead channel was given the usual gain and volume controls. Unfortunately, the channel change can only be made manually by means of a small push button, the connection of an external footswitch is not possible.

As a small FX section, a delay / reverb unit was built in, where you can select one effect at a time with a push button and mix it to the original signal continuously. An On/Off switch and a large blue LED complete the upper control front. All controls are equipped with very nice chrome heads, which gives the front panel a very noble flair.

As additional connection jacks, the 12 Gauge has an external speaker out, a line out, a headphone jack and a jack for feeding external sound sources such as MP3 players, workstations, etc.. All connections are in 6.35 mm jack. As with most combos of this type, the jacks have been routed out of the bottom of the case, which means a bit of fiddling while connecting the cables, but in return protects the plugs from accidental kinking.



Practice:

After switching on the amplifier, the bright blue LED shows the operating status of the amp. One has at the moment anyway the feeling that many manufacturers try to break away from the classic red LED. To avoid confusion between the popular channel colors green and orange, many manufacturers therefore opt for blue.

All potentiometers run very smoothly under a slightly increased force. Optics usually have their price, for example the black orientation points on the pots can hardly be seen after 2 meters in average lighting conditions. But since this is a practice amp that will most likely never climb a big stage anyway, this point is negligible.

The clean channel is once again a strength of this transistor amp. Chords and single lines come out clear and crisp. The very effective tone control has to be mentioned here. While with many amps in this price range you can only change nuances in the frequency range, the tone control of the Gauge 12 manages to conjure up neat bumps in a frequency diagram.

The speaker does its job routinely, although of course you have to make some sacrifices in the sound culture, the speaker tends a little to nasal and squawking. I am quite sure that the amplifier will gain in tonal quality with a higher quality transducer.

In the distorted channel, the transparency and sharpness of the sound can be described as adequate. Distortion levels from light crunch to powerful distortion are adjustable, and the sound improves significantly with increasing volume. Once the speaker's voice coil gets to work properly, the amp loses much of its brittleness, which it still possesses at typical practice volumes.



Conclusion:

I admit it's a mystery to me personally how you manage to sell a product like the Kustom Gauge 12 J at a retail price of MSRP €110 while paying for manufacturing, shipping from the other side of the globe, transportation within Germany plus commissions for distribution and retail, and still make a profit.

Rarely have I had an amp in my hand that offers so much "Value For Money". If you're looking for an inexpensive practice amp with the more "grown-up" sound of a 12-incher, you'll find this Kustom amp a decent workhorse.

TEST: Eve audio SC 3070

Regardless of the industry, whoever dares to "penetrate" a closed product system either has to rattle a lot to draw attention to his product, or he convinces with exceptional qualities and has staying power. For the Berlin-based loudspeaker manufacturer Eve Audio, the second is undoubtedly true, as the company around founder Roland Stenz has left behind plenty of scent marks in the high-end studio monitor sector since its founding in 2011. Anyone who messes with the top dogs of the industry in the style of Genelec, Neumann and Dynaudio must indeed expect a lot of headwind, but Roland Stenz probably got the necessary tenacity in his GDR education in the field of radio and television technology up to the shareholder of ADAM Audio GmbH. With the EVE Audio SC3070, we have a comparatively compact midfiled monitor as the newest member of the company portfolio for testing.

The construction of the EVE Audio SC3070

As with almost all Eve Audio products, the EVE Audio SC3070 has DSP technology built in, the construction of which we will read about later. The monitor has a three-way system, but not as often used in pure column arrangement was installed, but with a linear arrangement in the tweeter and midrange with external placement of the Tietöner. Due to the design, there is therefore always a left and a right box version, this should be considered when buying. With a price of €1,699 each, Eve Audio therefore also bumps directly into the Neumann KH 310 A category, which are known to have a very good reputation and are a worthy competitor.

Let's first take a look at the speaker lineup of the EVE Audio SC3070. According to the claim of a midfiled system, the speaker must have enough headroom to evenly and "relaxed" acoustically illuminate medium-sized rooms, which is taken over by a total of 335 watts per speaker at a maximum SPL of 120 dB per pair, with 185 watts for the 6.5-inch woofer, 100 watts for the 4-inch midrange and 50 watts for the tweeter. As with all Eve Audio speaker cabinets with 3 or more paths, the comparatively generous power rating of the midrange driver is noticeable here, an indication of the focus on very good midrange reproduction, with which other Eve Audio monitors have already scored. The frequency response is specified with 35 - 25000 Hz, the crossover frequencies are at 320 and 2800 Hz.

The corporate identity of the Eve Audio family can already be seen at first glance with regard to the individual speakers. Once again, woofers and midrange drivers consist of a fiberglass-coated honeycomb cone, which due to their low weights react very quickly to impulses, but in combination with a soft suspension still have the necessary torsional stiffness at strong deflections. Equally characteristic of the Eve Audio sound is the RS3 Air Motion tweeter, which is now also very popular in many large studios due to its balanced sound behavior. To protect the tweeter from external influences, a protective grille is included with the speakers, which magnetically adheres to the tweeter surround.

With the dimensions (W x H x D): 340 mm x 250 mm x 310 mm, the system must be described as extremely compact for a midfield system. The weight of 9.8 kg is also comparatively moderate, but one should always keep in mind that the speakers require a proper stand or other appropriately equipped support. A placement on the desktop is not possible for haptic reasons. However, the comparatively large depth of the monitor in relation to its lateral expansion is striking, a fact that will probably be noticeable in the bass reproduction.

The back

The back of the EVE Audio SC3070 is tidy and is limited to the important basic elements along with the bass reflex port, which is located diagonally behind the woofer. In addition to the power socket and the power switch, we also have the option of voltage selection. Via three DIP switches we can choose between two different input sensitivities (+7 dBu / +22 dBu) and the (de-) activation of the internal filters or the volume control. As input connectors there are balanced XLR and unbalanced RCA. All inputs are analog, there is no digital input.

The DSP control

As already mentioned, the EVE Audio SC3070 has an active DSP management, which is reflected in particular in an elaborate sound control. Via a push potentiometer, which is enclosed by an LED ring, several functions can be controlled at once and their settings checked by pressing the button, moving the illuminated LED to the area to be processed and then pressing it again. The following controls are possible:

Activate Standby Mode
Volume Adjustment: The volume setting can be adjusted in steps of 2 to 0.5 dB, depending on the volume range.
Low Filter: A shelving bass boost / bass cut, which boosts or cuts all frequencies below 300 Hz in 0.5 dB steps
High Filter: the same as in the bass range, only all frequencies above 3 kHz
Mid Filter: A bandpass filter that allows boosting/cutting up to 3 dB in 0.5 dB steps at 1 kHz.
Desk Filter: A special frequency processing that compensates for the desktop's radiation pattern by boosting frequencies at 80 Hz and cutting them at 160 Hz, also adjustable in 0.5 dB steps.

Should anyone feel disturbed by the LED wreath, it can also be optically deactivated completely.

The EVE Audio SC3070 in practice

Two points are the first to strike the listener as soon as you hear the first sounds from the speakers. The first is the very powerful bass that can be produced by the speaker even without a subwoofer. Due to the small cabinet dimensions, you really wouldn't expect this strong presence from the monitors, especially as far as the real low bass range below about 80 Hz is concerned. However, those who have already dealt a bit with the Eve Audio portfolio will already know the disproportionately good bass reproduction from the company's near field monitors. Even in the flat EQ setting, the bass range is very well defined and does not require any further adjustment, at least in my rooms. Even heavily bass-heavy productions are transmitted cleanly and accurately, no droning, no unnecessary "thickening" and thanks to the strong power reserves even in medium to higher volumes an accentuated reproduction.

The second point that comes to the fore is the midrange reproduction of the system. Especially if you are characterized by the 2-way near-field monitors, the basic sound of the EVE Audio SC3070 seems a bit "harsh", but this is due to the additional midrange driver. It transmits exactly the frequencies that are often lost due to the crossover frequency in 2-way systems. This significantly better transmission is particularly noticeable in the area of guitars and vocals, so that you need a certain listening time to train your brain to the changed basic sound.

Once this is done, however, the EVE Audio SC3070 proves to be a real game changer for many users, especially in the area of guitar sounds. You won't believe the details you suddenly perceive that remain hidden with various other monitors. In cooperation with the Air Motion Transformer, the box generates a very high resolution and excellent detail.

Eve Audio has also succeeded very well in getting a grip on the higher risk of phase problems that is inherent in the design of 3-way systems. I could not detect any problems during the entire test phase. It almost goes without saying that the system acoustically reproduces the usual parameters such as depth, phantom center, impulse behavior, etc. very well.

All in all, the EVE Audio SC3070 convinces in all areas, it was really not possible for me to find a point of criticism in the construction or the sound. One or the other will possibly criticize the absence of digital inputs, but that's about it.

Conclusion

With the EVE Audio SC3070, the Berlin-based company has another ace up its portfolio sleeve. Anyone who is in the transition area from nearfield to midfield and wants to expand their monitoring fleet with a 3-way system, is absolutely right with the system.

The monitor convinces with a strong bass response, a very good impulse response and last but not least, by the now legendary Eve Audio midrange reproduction, which increases the richness of detail of the sound material many times over.

If you are looking for an extremely compact midfield monitor with outstanding sound characteristics, you should definitely test the EVE Audio SC3070, it's worth it!

TEST: Eve audio SC 408

When a shipment of monitors is delivered by a shipping company, you know as a tester that something special is about to happen before you even hear the first sound. Theoretically, the 30 kilogram bolides could have been shipped as 2 individual packages, but strapped to a Euro pallet, the two Eve audio SC408 monitors look more than just impressive in their massive outer packaging. To what extent the touch of the monstrous is also reflected in the sound of the construction and how a single person manages to maneuver 30 kg onto a high stand without scratching it will be shown in the upcoming test.


The construction of the Eve audio SC408 test

That the Eve audio SC408s are not the usual near-field suspects in terms of sound and performance, one realizes already during the "unboxing" so popular on the Internet. If I had created a video of the process, you could have a good laugh at how I try to free the 30 kg Wämmser from their high-quality, tight-fitting outer packaging by attempting to lift them out. This attempt can be saved, since the foam persistently remains between the monitor and the box, especially since lifting 30 kg is a very manly department in itself. The only variant that works, as long as you don't want to destroy the outer packaging, was to carefully pull the product out from the side. So far, so good.

Already the pure performance data (2 x 250 watt woofer + 250 watt midrange + 50 watt tweeter) together with the dimensions (W x H x D): 710 mm x 330 mm x 440 mm indicate that the target audience of the Eve audio SC408 in this case is not the ambitious home recording studio, but rather one is in the professional field, which is further supported by a retail price of just under 3,000 € per box. Along with that, you should also check your rooms to see if they are at all up to a 1600 watt duo. After all, the Eve audio SC408 is not a nearfield but a midfield monitor. A perfect spatial alignment along with appropriate damping, especially of the low frequencies of the control room, are just as much a basic requirement for the system as a minimum size of the room. Otherwise, there is a risk that the Eve audio SC408 will literally "smash" the acoustics due to its performance. You don't build a Tesla drive into a Mercedes A-Class.

In order to place the monitors optimally in the room, I chose Fame monitor stands this time, which are the only ones in my collection that have a flat, partly foam-covered support surface and place the speakers at a height of about 1 meter. The distance to the monitoring position is 180 cm, the distance to the wall behind it 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 Eve audio SC408

Interestingly, the Eve audio company was created by Roland Stenz, who used to be the CEO of the Adam Audio company. Although it has only been on the market for a few years, the company already has an extensive catalog, starting with budget nearfield monitors in the 300 euro league, with the tested version being the top dog at the other end of the scale.

The Eve audio SC408 is an active, 4-way midfield monitor that features two 8-inch "Silvertone" fiberglass woofers rated at 250 watts each, a 5-inch midrange driver rated at 250 watts and a 1-inch AMT tweeter rated at 50 watts, and according to the manufacturer, has a frequency response of 30 Hz - 21 kHz. The sound pressure of the system is stated at 118 dB SPL. Considering the installed components, one also takes these values from the manufacturer without hesitation, i.e. an additional subwoofer is not needed. Eve audio calls the system a 4-way system, since 4 different drivers are used. The internal DSPs operate at 192 kHz and control the volume, crossover frequencies and equalizer functions. All speakers are secured with limiters, separating at 250 Hz and 3 kHz. The system was developed in Berlin, where the final acceptance of the system also takes place. The system is built in China.

Front and rear of the Eve audio SC408

On the back, the connection panel welcomes us next to the standard XLR an unexpected RCA input, which I would not have expected here. Via 4 mini switches (one is not assigned) you can lock the DSP functions and select the input level between +7 dBu and +22 dBu. Although in most cases one is well advised with +7 dBu, there are very high levels in some studios, which can then also be compensated in the +22 dBu setting. There is also a ribbed element on the rear panel, which serves to cool the system. It gets warm during operation, but not hot.

Regarding the front, you should first decide whether you want to operate the system horizontally or vertically. From the factory, the system is configured for horizontal operation. However, if you want to position the Eve audio SC408 vertically, you have to rotate the tweeter / midrange array by 90 degrees. This can easily be done in a few minutes. To protect the sensitive tweeter from external influences, you can also attach a protective grille, which adheres magnetically.

The system's control center is located on the top right, as seen from the midrange. Via a push-poti you get to the respective menu, which, if you have enabled editing on the back of the case, edits both the volume and the corresponding filter settings. The control is gridded, i.e. the annoying adjustment of the volume balance between the boxes, which is unfortunately still found especially in the budget class, is fortunately omitted.

In addition to a special desk mode, which defuses the low-mid range, the frequencies can be raised or lowered in 0.5 dB steps via 2 shelving filters (> 300 Hz, < 3 kHz). The optical control is done via a LED ring, which can also be edited in its brightness. If the potentiometer is pressed for longer than 3 seconds, the system goes into standby mode. All settings are automatically saved and automatically loaded at the next activation.

The Eve audio SC408 in practice

While powering on and booting up the system is completely silent, there is a very quiet "discharge pop" when deactivating, but it is so quiet that it is hardly noticed and does not stress the speakers in any way. If you look at the construction of the Eve audio SC408, the two 8-inch woofers naturally catch the eye first, which encourages the expectation of a voluminous bass reproduction. In fact, "what you see is what you get" applies here, meaning that the bass reproduction of the system is beyond criticism.

The bass is tight, well articulated and doesn't tend to be undifferentiated at any volume. Especially at higher volumes, the low frequency range shines, which is not to be neglected, especially in a midfield system. After all, it is important to ensure a clean localization of the signal even at a distance of 4 meters and more, which the Eve audio SC408 succeeds excellently. However, as already mentioned, it is important to pay special attention to the room acoustics and to address the issue of bass traps if necessary. With their massive air movement, the 4 woofers immediately punish any spatial inadequacy with a standing wave, which must be avoided at all costs.

Next, we'll take a look at the high frequency range. All users who have the facial expression of a freshly cut and to be eaten lemon because of the sometimes harsh reproduction can lean back and relax. In contrast to some representatives of the cheaper guild, the trebles in this case almost blend softly, but in any case very restrainedly into the sound picture. There is no trace of harsh or even biting highs, but instead a very fine resolution, which also reproduces the slightest flickering beyond 14 kHz sovereignly.

Now we come to the absolute highlight of the Eve audio SC408, the midrange reproduction. Rarely have I heard a system that generates such a well-structured resolution between 1 - 2 kHz, precisely the range that must be covered by the woofer in a 2-way system. However, this is exactly where the crucial guitar frequencies are, especially when it comes to distorted or high-gain variants. One could even go out on a limb and speak of a system within a system. It is almost frightening what the midrange driver of the Eve audio SC408 reveals in terms of subtleties that are downright swallowed up in comparable systems. Simply outstanding!

In terms of spatial resolution and depth, the Eve audio SC408 also leaves a very good impression, provided you take into account the dimensions of the system. The phantom center is cleanly punctuated, but a minimum distance between the speakers is required for perfect spatial staggering. As already described in detail, we are dealing with a midfield system. It's not that the speakers wouldn't sound adequate at a smaller distance, but you're depriving yourself of a large spatial component that the system generates when perfectly aligned.

The system also has a very good impulse fidelity, whereby the comparatively high weight of the individual speakers certainly has a share in this. Percussive elements or even the quick succession of kick drum beats are easily handled by the system, which manages a clean reproduction even at high to very high volumes. In general, it seems as if the system really "breathes" at a certain volume. This does not mean that the system is not convincing at moderate volumes, but 800 watts per side want to be "tickled" a bit before they can show their full sound.

Conclusion

With the Eve audio SC408, the Berlin company has a product of the absolute top class in the midfield area at the start.

TEST: KS Digital C-88 Reference

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: 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.
