RCF NX915-SMA Description
Whether you're running it as a stage wedge, main PA speaker, or paired with a subwoofer, the
NX915-SMA adapts to your live sound needs with ease. The 15" woofer, combined with a high-performance 1.75" compression driver and RCF's proprietary TRW waveguide, offers rich, detailed coverage at high volume without distortion.
Inside the tour-ready plywood enclosure is a 2100W Class-D amplifier—50% more powerful than its predecessors—delivering fast transients, deep bass, and balanced mids. Thanks to
FRFR tuning, it’s also a perfect fit for electric guitar and bass players using amp simulators.
RCF's
BMC algorithm manages low-end without phase-warping high-pass filters, maintaining signal integrity and enhancing transducer durability. The
FiRPHASE filtering ensures uniform sound distribution with minimal latency. Whether used on a pole, as a floor monitor, or in an install, this speaker brings next-level clarity, reliability, and versatility.
