THIS LISTING IS FOR A PAIR OF RCF ART315A MK4 ACTIVE 15" SPEAKERS

RCF ART 315A MK4 400 WATT BI-AMP 15" 2 WAY ACTIVE PA SPEAKER (PAIR)

Active speakers for live sound reinforcement and stage monitoring as well as distributed sound systems for clubs, music venues and corporate events. ART 315-A MK4 is the ideal speaker when an exceptional full range, outstanding bass reproduction and accurate high frequency delivery are required.

THE ART 3 SERIES DESIGN

ART 3 speakers are ideal for the musician or sound provider. Their plug ‘n' go design is simple yet powerful: double input (XLR or Jack), one volume knob. Cabinets are moulded on a special polypropylene composite material designed to dampen down vibrations even at maximum volume settings. From moulding to the final texture, ART3 offers maximum reliability and strength for intensive use. The ART 3 MK4 are equipped with handles for greater portability.

The ART Series is the beating heart of RCF. These multiple purpose active speakers represent the finest examples of audio design in a rugged composite cabinet, now in black.

The MK4 Series is equipped with a new generation of 2-way Class-D fan-less amplifiers, high-powered woofers and the latest compression driver technology, plus a redesigned front grille.

The ART concept offers the best audio choice for a multitude of live sound applications in a plug‘n'go device.Just connect your microphone, your mixer or your audio device to the speaker and turn up the volume: there are no complex menus, no knobs to understand.

POWERFUL CLASS D AMPLIFIERS

The integrated DSP manages full loudspeaker processing, FiRPHASE filters, crossover and EQ, soft limiter, and dynamic bass boost. Class-D power amplifier' s technology packs huge performance operating with high efficiency into a lightweight solution. The amplifier features a solid mechanical aluminium structure which not only stabilises the amplifier during transportation but helps the fan-less heat dissipation.

A NEW PERSPECTIVE ON LINEARITY

RCF speakers are designed by using FiRPHASE, a proprietary and advanced FIR filtering technology, conceived for delivering transparent sound, absolute clarity and perfect stereo images to the listener. The FiRPHASE algorithm optimizes dynamics, amplitude and phase patterns, ensuring at the same time minimum system latency.

SWITCHABLE EQ MODE

A switchable EQ Mode makes it easier to select among two different equalisation presets:

- Extended response switch that slightly emphasizes the bass response for playback music and low volume applications;

- Linear response switch, when the speaker is used to amplify a live mix. The amplifier has a built in limiter circuit to prevent clipping or overdriving the transducers.

SUPERIOR DRIVERS

The 15" woofer delivers a deep and accurate reproduction of the mid-bass frequency range while the 1" compression driver offers a very open and natural midrange sound and extreme precision in high frequency reproduction.

FIRPHASE

RCF speakers are designed by using FiRPHASE, a proprietary and advanced FIR filtering technology, conceived for delivering transparent sound, absolute clarity and perfect stereo images to the listener. The FiRPHASE algorithm optimizes dynamics, amplitude and phase patterns, ensuring at the same time minimum system latency.

PHASE MATTERS

The design of the FIR filter for this specific purpose should start from an accurate measurement of the loudspeaker phase. The FiRPHASE algorithm uses this measurement and adapts the loudspeaker's phase without touching the amplitude equalization. The heart of the advanced technique used by FiRPHASE is a recursive method (Least Squared method) combined with a proprietary algorithm that calculates the best FIR filter coefficients set in according to amplitude and phase constraints. The algorithm corrects phase and amplitude (when necessary) by taking into account the weak points of the transducers and the resonances or cancellations due to the cabinet of the loudspeaker. Despite the design perfection of our transducers and cabinets, we realize that the phase corrections are the "missing point" for the perfection. This technique allows a deep control of phase at mid-low frequencies with relatively small filters, reaching a higher resolution than that one as theory suggests.
