Overview

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

RCF's Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. Class-D amplifiers deliver ultra-fast attack, realistic transient response and impressive audio performance. The amplifier features a solid mechanical aluminium structure which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. All the Art 7 series amplifiers present SMPS power supply section in order to produce maximum output and minimum transportation weight.

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.

Components:

SUPERIOR COMPRESSION DRIVERS

The ND940 large format Compression Driver with 4" voice coil is the key feature of the ART 745-A. The extremely low crossover point of 650Hz is a must for perfect reproduction of the vocal range.

DIRECT DRIVE TECHNOLOGY

The voice coil features a high-temperature kapton former. The assembly process takes advantage of the RCF proprietary Direct Drive technology. The diaphragm's suspension has been designed following extensive studies aimed at minimising distortion and extending low frequency range.

POWERFUL WOOFER

The low-frequency transducer is a high-power 15'' woofer with a 3.0'' voice coil, delivering a punchy bass. Reproduction of the mid-bass frequencies is accurate, transparent and free from distortion.
