RCF celebrates a 25-year history of ART speakers with the introduction of the ninth generation of the series – ART 9. All models boast a 2,100W, two-channel Class-D amplifier with advanced DSP processing.
50% more powerful than previous models, ART 9 manages extremely high sound pressure levels. The amplifier is energy-efficient so there is no need for a cooling fan. The circuit is attached to a solid aluminium heat exchanger in the back of the unit with no moving parts. Performance improvements are assured by new RCF transducers, featuring advanced materials such as Kapton, Titanium, and Neodymium.
The new 1.75″ compression driver with Polyimide-Kapton dome features a new bonding technology and reinforced ribs that make it 10 times more durable than previous models. Newly designed woofers gain more stability over high currents, with less distortion. Every woofer design is tested with a 200-hour continuous signal to stress the transducer at extreme levels.
The innovative electroacoustic design of ART 9 lies within the housing of the speaker. The new True Resistive Waveguide (TRW) 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. TRW mimics a resonance-free pure resistive load reducing the high-frequency distortion of a classic horn. With its asymmetric acoustic radiation, the coverage angle of the waveguide provides constant directivity to the entire listening area with a balanced stereo panorama.
These components work in harmony with two RCF exclusive DSP algorithms, one for phase linearisation and crossover design, the other for woofer excursion management. FiRPHASE, a superior digital FiR technology, allows for a coherent distribution of sound without phase distortions, ensuring minimum latencies to the system.
With proprietary FiRPHASE technology, the new shape, and the placement of the vented ports, the speaker now acts as a single source for a true sound image. The woofer excursion management feature, Bass Motion Control works by creating a complete map of the dynamic behaviour of the transducer, to generate a custom algorithm that only limits over-excursions. This gives total freedom of signal reproduction, avoiding both high-pass filters and large-band limiters. The speaker is now allowed to reproduce the input signal at all volume levels for the entire audible spectrum, maintaining all nuances of the music with deep, detailed bass response.
The sleek black cabinet uses a special polypropylene composite material with a radically new construction concept. RCF’s M-Brace internal reinforcement design connects four sides of the enclosure with the amplifier, preventing any deformation for a completely inert body, with augmented acoustical damping even at maximum volume settings. M-brace also performs exceptionally well for greater resistance to mechanical stress.
The ART 9 is easy to move and transport with ergonomic handles on both sides and the top. The bottom side includes a steel pole socket for mounting on a stand or subwoofer pole. Each model can also be flown, wall- or truss-mounted using multiple M10 rigging points and special accessories.
The ART 9 Series consists of six new models, ranging from 10″ to 15″ woofers and share the same 2100 Watts power amplifier. ART 945-A is the largest, most powerful model of the series delivering an impressive 135 dB max SPL featuring a 4″ titanium compression driver, and a neodymium woofer that goes down to 45Hz. The ART 935-A and ART 932-A can produce respectively 134 dB max SPL and 133 dB SPL, sharing the same 3” titanium compression driver. The exceptional clarity and minimal distortion of the new Kapton driver of the ART 915-A, ART 912-A and ART 910-A features remarkable SPL and power to weight ratio.
The ART 9 Series is an evolution of the ART speaker concept and a revolution in professional portable sound. RCF offers a new standard in pro audio with a remarkable electro-acoustic design and professional versatility, all packed in a solid, tour-ready cabinet also suitable for high-power install applications.
