The latest member of the RCF ART Series of loudspeakers—the new 2-way, active ART 745-A—is outfitted with a 4-inch voice coil compression driver joined by a 15-inch woofer (with 3.5-inch voice coil).
The newly engineered ND 940 compression driver is further bolstered by a neodymium magnet structure, and it feeds a 90- x 60-degree (h x v) constant directivity horn. The driver/horn combination fosters a crossover point of 650 Hz, meaning that almost all of the vocal range is handled by the driver, enhancing impulse response, fast waterfall decay and efficiency that results in exceptional vocal clarity and projection.
Performance is furthered with the 15-inch woofer that also incorporates a neodymium magnet structure, engineered to supply very linear response and precise, deep low-frequency control.
Transducers are driven by a class D 1,400-watt (peak) onboard power amplifier, joined by comprehensive DSP that includes crossover, equalization, phase alignment, soft limiting and loudspeaker protection. The amplifier has a solid mechanical aluminum structure that not only stabilizes it during transportation but also assists in heat dissipation.
The rear panel input/output configuration of the new ART 745-A includes both XLR/jack (combo) balanced inputs, XLR output link, volume, and a switchable EQ mode (flat/boost).
The cabinet, designed for use in standard or stage monitor modes, is molded of a special polypropylene composite material designed to dampen vibrations, even at maximum volume settings. The reflex porting has also been re-sized to offer more efficiency, while ergonomically designed, forged aluminum handles with rubber handgrips supply greater portability.
