RCF ART 945-A Two-Way 15" 2100W Powered PA Speaker with Integrated DSP

The 15" RCF ART 945-A is a highly flexible, easy to use, 2100W powered PA speaker for today's working musicians, singer/songwriters, mobile DJs, and other sound providers. The speaker works in a variety of orientations and configurations for use as a main PA or stage monitor. When used as a main speaker, a pair of ART 945-A's is well equipped to cover an audience of up to 450. A push button on the back of the speaker allows you to physically switch between three preset modes: Linear, for standard applications; Boost, which provides loudness equalization for background music played at low volumes; and Stage, for using the speaker as a stage monitor. The ART 945-A employs True Resistive Waveguide technology, which incorporates several refinements of the transducers and the vented port design to create a resonance-free signal that reduces high-frequency distortion. The speaker also utilizes Bass Motion Control (BMC), which bypasses the need for a high-pass filter and instead uses an advanced woofer excursion management feature that can handle the lowest audible frequencies without affecting the woofer stability, with extended linearity and better sound integrity. A single combo XLR-1/4" connector can accept both unbalanced and balanced signals. There is also an XLR Thru-Output for daisy-chaining to additional speakers or other audio equipment. The highly efficient 2100W Class-D bi-amplifier delivers 1400W to the 15" woofer and 700W to the 4" titanium/neodymium compression driver, which provide full-range audio (45 Hz to 20 kHz) with a sound pressure level powerful enough to ensure the entire audience can hear your performance. The speaker features True Outdoor Protection (TOP) PowerCON TRUE1 power input and output connectors. These ruggedized sealed connectors feature not only IP protection but also UV resistance approved according to UL50E. The ART 945-A includes a power cord.

Power that Moves
With 2100W 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 fanthe amplifier is attached to a solid aluminum heat exchanger in the back of the unitwith 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 Cabinet Design
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
