ART 735-A MK4
ACTIVE TWO-WAY SPEAKER
- 1400 WATT 2-way peak power
The ART 735-A MK4 is a unique speaker in its category. The titanium dome, 3.0″ voice coil neodymium compression driver offers a unique vocal clarity and sound projection. The 15” neodymium woofer offers an extremely linear response and a precise, deep low frequency control. The transducers are produced using the most advanced assembly technologies. The amplifier delivers 1400 watts and is controlled by a DSP that takes care of crossover, equalisation, phase control, soft limiting and speaker protections.

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.
The amplifier presents both XLR In/Out connectors and a Jack input for the maximum connection versatility.
SWITCHABLE EQ MODE
A switchable EQ Mode makes it easier to select among two different equalisation presets:
– BOOST: extended response switch that slightly emphasizes the bass response for playback music and low volume applications;
– FLAT: 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.
An easy to reach volume knob on the back allows to set the overall volume of the speaker according to its application.
3 status LEDs – Limiter / Signal / Status are provided for monitoring the system.
SUPERIOR COMPRESSION DRIVERS
The ND840 Compression Driver in pure Titanium with a 3” voice coil is perfect for a crossover point at only 800 Hz. This allows a better impulse response, fast decay and superior efficiency. Lightweight and powerful, our neodymium drivers are a reference in performance and reliability.
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.
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.
THE ART 7 SERIES DESIGN
The RCF ART 7 Series has earned the prestigious international Red Dot Design Award in the Product Design category. Receiving the renowned Red Dot acts as proof of the excellent design achievements of professionals and up-and-coming talent alike, thus symbolising a seal of quality. With its outstanding and innovative design, the Art 7 Series has succeeded in one of the most renowned and most difficult international design competitions worldwide. High quality materials, precise manufacturing, careful assembly and extensive quality control procedures complete the groundbreaking design work of the RCF R&D team.
The sturdy, ergonomic cabinet is easy to carry thanks to the rubber-coated plastic handle. Take the ART 7 everywhere with you.
A side handle with internal rubber handgrip allows to firmly hold the cabinet and move it easily. Ergonomic design and carefully designed proportions, for all your transport needs.
At the bottom of the speakers there is a robust steel pole mount, allowing to place the speaker on a stand or on a subwoofer with full safety and stability.
Thanks to the rear profile of the cabinet, the ART 7 Series speakers can be easily used as stage monitors whatever the needs of musicians. Internal reinforcements prevent any deformation of the cabinet.
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.
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 Squares 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 best sound reproduction. 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.
