NX 915-SMA speaker is a stage monitor designed for sound providers, musicians, bands, and DJs. The combination of a 1.75” compression driver, 15” woofer, two-channel 2,100W amplifier, and the TRW waveguide produces coherent 100° x 70° coverage for the listening area with up to 131dB SPL of distortion-free sound. Used as a stage monitor, stand-alone speaker system, or satellite paired with a subwoofer, the NX 915-SMA blends high performance and reliability in a compact package. Combining RCF proprietary FiRPHASE and Bass Motion Control DSP processing, NX 915-SMA Series speakers deliver absolute clarity and deep, powerful bass response. The tour-ready, rugged all-wood cabinet is easy to carry and set up on stage or on a pole.
