The NX 915-A is masterfully engineered from the ground up to deliver stellar audio performance for solo musicians, bands, and DJs. The combination of a 1.75" compression driver, a 15" woofer, a two-channel 2100W amplifier, and a constant directivity waveguide produces coherent 100° x 60° coverage for the listening area with up to 131 dB SPL, distortion-free sound. Used as a stand-alone speaker for an FOH system, satellite (with subwoofer), stage monitor, or flown speaker, the NX 915-A blends high performance and reliability in a compact package. Blending RCF's proprietary FiRPHASE and Bass Motion Control DSP processing, NX 9 Series speakers are perfectly tuned for each model, delivering absolute clarity and deep, powerful bass response. The tour-ready, rugged all-wood cabinet is easy to carry and secure to install on a pole, flown wall, or truss mount using the dedicated rigging points available.
