TEST: RCF ART 915-A

 The ART series from RCF has made a very good impression on me so far, especially since the active full-range speakers delivered a very "mature" sound in relation to their dimensions, which was in some cases significantly higher than what one would normally expect in this performance and size class. The third representative of the ART series, the RCF ART 915-A, is the battleship of the series, which for the first time is also a category higher than its competitors in terms of dimensions.

Structure and concept of the RCF ART 915-A

The first thing that strikes you in direct comparison with the smaller 932-A is the lower price! Bigger speaker, lower price, how can that be, many people will probably ask themselves. The question is put into perspective when you look at the price of the 912-A, which is actually priced below the 915-A. So what makes 3 instead of 1 so extraordinary?

The difference can be seen in the loudspeaker configuration, with the tweeter in combination with the crossover frequency playing a special role. While the 93 series has a 3 inch neodymium compression driver with a crossover frequency of 800 Hz, a comparatively low crossover, the 91 series works with a traditional 1.75 compression driver that separates at 1800 Hz. In return, this means that the woofer is better supported in the midrange reproduction and the typical midrange hole that often appears in the classic 15/1 combination is much less common in this combination. Furthermore, the neodymium combinations create 2 dB more sound pressure, which is reflected in the form of 133 dB compared to 131 dB Max SPL @ 1m. RCF states that all woofers are tested for over 200 hours to detect any quality problems before they are delivered.

Otherwise, the design is very similar to the other representatives of the 9 series, which were already convincing in the smaller versions. Here, too, the entire product is manufactured in Italy, which on the one hand counteracts the omnipresent supply chain problem with China and on the other hand supports Europe as a production location with its higher standards in terms of labor and human rights. You may call me naive, but I will probably always be a "Support Your Local Dealer" sympathizer, although some electronic components in the RCF ART 915-A will definitely come from China.

This representative of the 9 series also shines with a wide range of applications due to its high flexibility. Due to its asymmetrical housing shape, the RCF ART 915-A can cover several sound options at once, although the voluminous exterior in combination with corresponding subwoofers clearly points towards a small PA. Even without the appropriate woofer support, one or two DJs will use the high-stand version as a mobile sound system, which should also be sufficient for small halls. It can also be used as a floor monitor and sidefill, although the stability and tipping safety are completely sufficient for regular wedge operation, but do not come close to the stability of a pure wedge. The system also has M10 threaded inserts on the top and bottom, or side panels of the housing for flown fixed installations. For high-stand operation, the box has a robust 36 mm steel flange on the bottom.

With dimensions (H x W x D): 717 mm x 415 mm x 410 mm, the box is in the middle segment in terms of transportability, although the 24.2 kg weight puts a lot of strain on the arms and a second person may be needed to place it on the high stand. The housing of the RCF ART 915-A is made of polypropylene, which, with a combination of comparatively low weight and good elasticity, should absorb both internal vibrations and major external impacts well. For better protection, I would also recommend the corresponding protective cover from RCF, which can be purchased separately. Even if it is “just” a sound system, worn-out speakers always leave an inferior impression.

Two generously sized recessed grips on the sides ensure good handling and easy transport, which not only make it more comfortable to carry, but also make it much easier to balance on a stand. The two grip slots on the top and bottom of the housing, which are familiar from the smaller models, are missing here, probably because a weight over 20 kg would no longer be adequately transportable in this form. The loudspeaker equipment consists of a 15" woofer made in-house and a 1.75" tweeter, which together can deliver 1050 watts peak, i.e. around 500 watts sine, and boasts 2100 watts peak for those with a penchant for numbers. The frequency response of the system is specified as 45 Hz - 20000 Hz, the horizontal radiation angle is 100°, the vertical radiation angle 60°. The manufacturer also points out the new filter technology called "Firphase" as a special feature in this series, which, according to the company brochure, guarantees "a transparent sound image, absolute clarity and a perfect stereo image with minimal latency without phase distortion".

In terms of accessories, RCF does indeed offer a wide range of stands and mounts, both for use close to the ground and for flying. It is worth checking out the manufacturer's website to see if you can find something that comes closest to your personal use case.

The back

As with the other two representatives of the 9 series, which have already been discussed, all connections are on the back of the housing, although RCF has also reduced the operating options to a minimum here and transferred the entire sound signal management to a mixer connected in front of it. To what extent this represents an advantage or disadvantage is something each user has to find out for themselves, but the fact remains that the advantage of a spartan equipment is that even less experienced users cannot cause major damage in the case of mismatching. 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 are flat on the panel. The alignment and arrangement is identical to the 932-A, so we also find the following controls here. An XLR / TRS combo input socket, combined with a volume control, serve the user as input management. In addition, a push button enables a rough pre-selection of the applied signal level, consisting of the presets "Linear", "Boost" and "Stage", the respective activation of which can be read off via 2 green LEDs. Unfortunately, there is no gain control here either, so you should keep an eye on the overload displays in the master area when outputting the signal via the mixer. The system also offers an XLR out for daisy chain operation. The system status can also be read off via 2 LEDs (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 cold device socket and the 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 also behave accordingly.

The RCF ART 915-A in practice

Of course, the area of ​​application of the RCF ART 915-A is very broad, but the primary purpose will most likely be as an easy-to-transport sound system in the DJ area. This is where the RCF ART 915-A can really show off its strengths, which is particularly evident in the combination of relatively good transportability together with a powerful level. Nevertheless, like other active speakers before it, the full-range box had to undergo my standard test routine for flexible full-range boxes, 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.

In fact, even with the linear setting, you can see that the 15-inch woofer used moves significantly more air than the slightly smaller sister models, thus enabling a better and more stable presence, particularly in the low bass range. I would even go so far as to say that with the RCF ART 915-A, depending on the sound material used and the size of the area to be sounded, you might be able to save yourself the need for a subwoofer. Despite the performance data, you should of course not have too high expectations of a real "physicality" in the low bass, but you should also not forget that this form of performance is only desired at real dance events anyway and is sometimes even perceived as disturbing in "normal" operation in the party area.

Here, the RCF ART 915-A offers a very tasteful solution that can be installed and operated without much effort. I personally found the mid-range reproduction of the system interesting. In general, when it comes to expectations, I'm always a little prepared for the classic mid-hole in a 15/1 combination, where the woofer is too sluggish due to its mass and the tweeter can't get down. I was all the more pleased that RCF got this problem under control surprisingly well. I couldn't quite figure out whether it was due to the slightly larger compression driver or the greater flexibility of the 15-inch, but the sound result convinced me across the board. For example, I've rarely been as impressed with the guitar playback in a 15/1 combination as I was with the RCF ART 915-A.

The system also impresses with its very stable sound, which is relatively balanced and without any unpleasant sharpness until shortly before the limiter is activated. Overall, this RCF system has to be given a very good rating, including a high level of flexibility in terms of application, particularly in relation to its price, which can be seen as quite cheap despite being manufactured in Europe.

Conclusion

With the RCF ART 915-A, the Italian manufacturer has a powerful sounding full-range speaker with a very stable headroom and unexpectedly good midrange reproduction in its range. The system is very flexible in terms of its use due to its trapezoidal shape and impresses with a neutral basic sound, which offers a very high level including decent sound pressure when required. Anyone looking for a powerful full-range speaker and sometimes wanting to do without a woofer should definitely try the system out.
