Designed to deliver stellar audio performance and versatility for intensive audio applications, the RCF NX 915-A is a highly flexible, easy-to-use, 2100W powered PA speaker for today's working musicians, singer/songwriters, mobile DJs, and other sound providers. The speaker works in a variety of orientations and configurations for use as a main PA or stage monitor.
The highly efficient 2100W Class-D bi-amplifier delivers 1400W to the 15" woofer and 700W to the 1.75" titanium/neodymium compression driver, which provide full-range audio (50 Hz to 20 kHz) with a sound pressure level powerful enough to ensure the entire audience can hear your performance. The NX 915-A utilizes RCF's proprietary FiRPHASE and Bass Motion Control DSP processing to deliver 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-mounted using the dedicated rigging points available.

- When searching for an extended bass with enhanced performance, RCF engineers found a way to remove the high-pass filter, replacing it with a forward-thinking approach. Introducing BMC (Bass Motion Control), the newly advanced woofer excursion management feature. The speaker equipped with BMC can handle the lowest audible frequencies without affecting the woofer stability, with extended linearity and better sound integrity.
- The BMC method works by creating a complete map of the dynamic behavior of the woofer, to generate a custom algorithm that only limits over-excursions. This gives total freedom of signal reproduction to the transducer. When high-pass filters normally protect the woofer motion from becoming destructive but change the phase behavior, the new BMC algorithm breaks conventional rules.
