RCF NX 915-A Description
The 
RCF NX 915-A is built to exceed the expectations of performers and sound engineers in demanding live environments. Whether used as a main FOH speaker, stage monitor, or paired with a subwoofer, the NX 915-A offers powerful, distortion-free audio reproduction with wide coverage and smooth frequency response from 45 Hz to 20 kHz.
At its heart is a 2100W two-channel Class-D amplifier—50% more powerful than previous generations—delivering fast transients, low heat loss, and energy efficiency. The 15" woofer and 1.75" compression driver are custom-designed for reliability and clarity, while the BMC algorithm ensures extended bass response without compromising stability or linearity.
The speaker’s rugged enclosure, made from weather-resistant plywood and coated for durability, features multiple M10 rigging points, a 35 mm pole socket, and ergonomic side handles for easy transport. Whether flown, pole-mounted, or floor-positioned, the NX 915-A offers unparalleled flexibility and performance, backed by RCF’s proprietary DSP processing, including FiRPHASE filtering for phase-coherent output and natural sound reproduction.
