RCF ART945A 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. Used as a stand-alone speaker for a FOH system, satellite (with subwoofer), stage monitor, or flown, ART945A packs high-performance and reliability in a compact enclosure. Designed to be the most flexible loudspeaker in its class, it also features multiple rigging points for fixed installation. Merging RCF proprietary FiRPHASE and Bass Motion Control (BMC) DSP processing, perfectly tuned for each model, audiences 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 pop straight on a speaker stand, or install via the rigging points. But where’s the microphone selector switch? Forget about plugging a mic straight into this one…with so much power under the bonnet, RCF has wisely decided this is strictly a “line level” input only. ART945A features True Outdoor Protection (TOP) PowerCON TRUE1 power input connectors. These ruggedised sealed connectors feature not only IP protection but also UV resistance approved according to UL50E.
