Description

ART 945-A is masterfully engineered to deliver stellar audio performance and versatility for intensive audio applications. The combination of neodymium transducers - 4" titanium compression driver, 15" woofer - two-channel 2100W amplifier, and the constant directivity True Resistive Waveguide produces coherent 100° x 60° coverage for the listening area with up to 135 dB SPL, distortion-free sound. Merging RCF proprietary FiRPHASE and Bass Motion Control DSP processing, perfectly tuned for each model, the audience will experience absolute clarity and deep, powerful bass response. The sleek cabinet uses a special polypropylene composite material with an M-brace internal reinforcement, making it easy to carry and secure to install on a pole, flown-, wall-, or truss-mounted using the multiple rigging points available.

Power that moves


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.

M-Brace: a new cabinet design


A professional appearance of an ART 9 cabinet is ideal for live events or installed applications. The sleek cabinet uses a special polypropylene composite material with a radically new construction concept. The grille cover is heavy-duty steel protecting both transducers and vented ports. The purpose-designed M-brace connects the four internal sides of the cabinet and amplifier, preventing any deformation for a completely inert body, with augmented acoustical damping even at maximum volume settings. It also performs as a reinforcement structure, for greater resistance to mechanical stress.

Bass Motion Control


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. The speaker equipped 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 rules.

New paradigms in electroacoustics


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.

Legendary transducers


Superior compression drivers
The ND940 Compression Driver in pure Titanium with a 4 inches voice coil allows a crossover point at only 650 Hz. This allows a better impulse response, fast decay, and superior efficiency. Lightweight and powerful, RCF neodymium drivers are a reference in performance and reliability.
Potent woofer
The low-frequency transducer is a high-power 15’’ neodymium woofer with a 3.5’’ voice coil that delivers tight, punchy bass. Reproduction of the mid-bass frequencies is accurate, transparent, and free from distortion.

Ready for heavy-duty applications


The highly innovative entertainment industry is permanently evolving accompanied by increasing demands on interconnection systems. Particular environmentally sealed connectors are highly requested for heavy-duty and harsh environment applications of entertainment equipment. ART 945-A features True Outdoor Protection (TOP) PowerCON TRUE1 power input connectors. These ruggedized sealed connectors feature not only IP protection but also UV resistance approved according to UL50E.
