TEST: RCF HD-10A MK5

 Between you and me, are there still passive full-range speakers with external power amplifiers? I feel like I haven't come across any in the last 10 years. Since the establishment of Class D power amplifiers, almost all passive systems in the power class up to around 2 KW have been obsolete, so it is of course not surprising that the new series from the Italian manufacturer RCF are active speakers. We have several examples to test, starting with the smallest version, the RCF HD 10-A MK5.

Structure and concept of the RCF HD 10-A MK5

It's hard to believe, but there is actually still a European production facility in the active speaker sector. Instead of the usual "Developed in home country, assembled in China", a proud "Made in Italy" lettering is emblazoned on the housing, which already gives it an ethical plus point. Like many other representatives of this performance class, the RCF HD 10-A MK5 tries to cover several sound options at once due to its asymmetrical housing shape, which increases its flexibility immensely.

With dimensions (H x W x D): 572 mm x 303 mm x 303 mm, the box can be described as very compact and, with its weight of 11.8 kg, it is also very easy to transport. The housing is made of polypropylene, which, with its combination of low weight and good elasticity, should also absorb rough external influences well. For better protection, you can also purchase a corresponding protective cover, which I would personally always recommend if the visual appearance of your equipment is important to you. The material also dampens any natural resonances that arise quite well. The name MK5 indicates that this model is already a further development. Among other changes, the effectiveness of the bass reflex openings, which are located in the upper part of the housing next to the tweeter horn, has been improved.

In terms of flexibility, the RCF HD 10-A MK5 can cover several areas at once. Firstly, the classic sound area in the form of P.A. or sidefill, thanks to the beveled back as a wedge, or with 2 M10 threaded inserts on the top and bottom of the housing for flown permanent installations. The box itself rests on 4 strong rubber feet in the portrait position, which give it sufficient support. For use with a high-stand, the box has a robust 36 mm steel flange on the bottom. A handle slot on the top of the housing and a generous handle recess on the side ensure good handling and easy transport, which not only increases carrying comfort, but also makes it easier to balance on a high-stand. The loudspeaker equipment consists of a 10" woofer made in-house and a 1" tweeter, which together can deliver 400 watts RMS, i.e. approx. 200 watts sine, and boast 800 watts peak for those with a fetish for numbers.

The frequency response of the system is specified as 50 Hz - 20000 Hz, the sound pressure is 128 dB (Max SPL @ 1m), the horizontal radiation angle is 90°, the vertical radiation angle is 60°. The crossover frequency is 2000 Hz, which can sometimes be higher than the usual 12/1 or 15/1 combinations due to the small animal hair dryer. As a special feature, the manufacturer refers to a new variant of the filter technology called "Firphase", which, according to the company brochure, ensures "a transparent sound image, absolute clarity and a perfect stereo image with minimal latency without phase distortion". Well then...

The back

As with many other representatives of this type, all connections are on the back of the housing, although RDF has reduced the operating options to a minimum. The advantage of a spartan equipment is always that even inexperienced users cannot cause major damage in the case of a mismatch. The disadvantage, however, is that experienced users have to make almost all frequency-related settings using an external console. All controls are installed very deep in the housing and are therefore very well protected from external influences, provided they lie flat on the panel. This is also necessary because the only rotary control on the surface unfortunately has no counter-lock on the housing and is therefore held rather wobbly only by the circuit board.

An XLR and a TRS input, combined with a simple volume control, serve the user as input management. In addition, a recessed mic / line slide switch allows a rough pre-selection of the signal level present. Gain control? Unfortunately not. The system offers an XLR out for daisy chain operation. What is a bit confusing, however, is that the TRS input is at the same height as the XRL out and has no labeling regarding its input function. I am sure that many users will mistake this socket for an output. The only sound control the RCF HD 10-A MK5 has is a "Boost" switch, which slightly increases the bass in music mode and is intended to generate a subtle loudness effect at low volume. The system status can also be read off via 3 LEDs (Power - green, Signal - green and Limiter - red).

Finally, in the lower part of the housing below the cooling fins of the system, there is the On / Off switch plus the IEC socket and internally installed main fuse. The system does not have a multi-voltage power supply and is approved for either 220 - 240 volts or 100 - 120 volts mains voltage. The values ​​of the fine fuses used behave accordingly.

The RCF HD 10-A MK5 in practice

I gave the RCF HD 10-A MK5 my standard test routine for flexible full-range speakers, i.e. operation as a floor monitor in the studio, high-stand operation indoors and high-stand operation outdoors up to a distance of 50 meters. From the very first sounds of the RCF HD 10-A MK5, the basic sound is comparatively balanced and finely resolved for this area of ​​application, which has nothing in common with the sometimes very harsh basic sound of some competitors. The mid-range in particular benefits from the 10-inch speaker, which is quite fast due to its size, which picks up the crossover frequency very nicely and enables a rounded basic sound. In terms of sound, the speaker is indeed impressive across the board.

The strong bass component of the system is indeed striking, especially when you consider the design. What is good for DJs can be bad for singers, as I personally found the bass part a bit too much of a good thing, especially with male voices. Unfortunately, the RCF HD 10-A MK5 does not have any further tone control, so as already mentioned, this can only be controlled using an external console. The lack of a gain control is also a little missed here and there. The gain slider can be used to adjust the sensitivity, but while, for example, the direct feed of a Beyerdynamic M88 in microphone mode enabled a very high volume, an MP3 player could only occasionally trigger the limiter when the volume control was turned up, meaning that a lot of the level was lost.

The speaker remains stable in terms of tone and resonance until shortly before saturation, and can also handle the odd peak without damage. Of course, the box cannot generate a "body bass" with its dimensions, but the bass content is quite sufficient for average sound, especially since the mid-range is balanced and the highs are very fine. The RCF HD 10-A MK5 is also impressive in floor monitor mode. The beam angle allows enough space vertically for practical use and horizontally still allows about one meter of usable space to the right and left.

Overall, the system has to be given a very good rating, especially in relation to its relatively moderate price despite being manufactured in Europe. If the DSP approaches to sound control were a little more generous, this would be a real exceptional talent in this performance class.

Conclusion

With the RCF HD 10-A MK5, the Italian manufacturer has a very good-sounding and extremely handy active full-range box in its range. The system is very flexible in terms of its use, offers a full-fledged bass content for its dimensions and impresses with good components and a practical feel. If you are looking for a small, powerful and very good sounding speaker and are not afraid of using an external console for the final sound control, you should definitely try out this speaker.
