ART 912-A & SUB 705 MK3 System

The most powerful amplifier in its class

RCF's improvements in transducer design make them stronger and powerful, so the amplifier follows the evolution. With 2,100 Watts of power, the 2-channel ART 9 Class-D amplifier is 50% more powerful than previous models, able to manage extremely high sound pressure levels with an ultra-fast attack, realistic transient response, and very low heat loss. ART 9 is very energy-efficient so there is no need for a cooling fan - the amplifier is attached to a solid aluminum heat exchanger in the back of the unit - with no moving parts. Being physically connected with the internal frame, the amplifier is firm and solid within the cabinet. The input circuit features a new low distortion design with an advanced safety limiter, maintaining the true character of the input signal at all levels. All ART 9 amplifiers are designed according to EN62368-1 for maximum safety and present a Switch Mode Power Supply section joining high-efficiency with minimum weight.

The advanced design of ART9 lies within the housing of the speaker. The new True Resistive Waveguide is the result of several refinements in both the transducers' and the vented ports' design with Finite Element Analysis, and constant measurement in RCF anechoic chambers. Thanks to FiRPHASE technology, the new shape, and the placement of the ports, the speaker now acts as a single ideal source for a perfect sound image. Acoustically, the TRW waveguide mimics a resonance-free pure resistive load reducing the high-frequency distortion of a classic horn. With its asymmetrical sound shaping, the coverage angle of the waveguide provides constant directivity to the entire listening area and improved stereo panorama.

High frequencies

The new 1.75" compression driver voice-coil design with Polyimide-Kapton dome features a new bonding technology and reinforced ribs make it 10 times more durable than previous models. We also redesigned the phase plug to increase sound clarity and precision, also improving coupling with the low-frequency transducer.

Low frequencies

Low-frequency transducer design gains more stability over higher currents, with less distortion, and is highly efficient in terms of heat dissipation. RCF quality control is very strict. Our woofers are tested with a 200 hours continuous signal to stress the transducer at extreme levels. Only the best woofer design can fit ART 9.

When searching for an extended bass with enhanced performance, RCF engineers found a way to remove the high-pass filter, replacing it with a forward-thinking approach. Introducing BMC (Bass Motion Control), the newly advanced woofer excursion management feature. Speakers with BMC can handle the lowest audible frequencies without affecting the woofer stability, with extended linearity and better sound integrity.

The BMC method works by creating a complete map of the dynamic behavior of the woofer, to generate a custom algorithm that only limits over-excursions. This gives total freedom of signal reproduction to the transducer. When high-pass filters normally protect the woofer motion from becoming destructive, but change the phase behavior, the new BMC algorithm breaks conventional rule. In combination with FiRPHASE technology, ART 9 & NX 9 have a level of DSP audio performance never achieved in this range of speakers.

The SUB 705-AS MK3 is a portable 15" high-power active subwoofer for live sound applications. It features a state-of-the-art transducer with a high-power ceramic magnetic circuit and a powerful Class-D amplifier that delivers sound pressure levels up to 131 dB with exceptional headroom. Designed as the ideal complement for 10" or 12" loudspeakers, it provides outstanding performance in any application. Rear panel controls include volume, EQ, polarity, and crossover frequency selection. The rugged all-wood cabinet with scratch-resistant polyurea coating makes it durable, easy to carry and install securely. With its versatility, sound quality, and high power output, the SUB 705-AS MK3 is perfect for small to mid-sized venues and portable applications.
