RCF NX 915-SMA 15-inch 2,100-watt Active Stage Monitor

The RCF NX 915-SMA is a capable powered stage monitor that delivers 2,100 watts of stage-filling sound by way of a 15-inch woofer and a 1.75-inch compression driver. This 2-channel behemoth boasts a linear 45Hz–20kHz frequency response and up to 131dB of maximum SPL. Perfectly tailored for both horizontal and vertical deployment, the NX 915-SMA's TRW waveguide produces coherent 100- x 70-degree coverage, ensuring that every corner of your listening area hears every detail. You can deploy the NX 915-SMA as a stage monitor, a standalone speaker, or as a satellite paired with a subwoofer. Whatever the application, RCF's proprietary FiRPHASE and Bass Motion Control DSP processing ensure distortion-free sound with the utmost clarity and deep, powerful bass. A road-ready all-wood cabinet, convenient carry handles, and a flexible pole mount round out the NX 915-SMA's outstanding features.

Robust 2,100-watt Class D amplifier

The NX 915-SMA features a robust 2,100-watt Class D amplifier, fine-tuned to deliver massive sound pressure levels with an exceptional attack, natural transients, and minimal loss of heat. What's more, the NX 915-SMA's unmatched efficiency allows this speaker to perform to its fullest without a cooling fan — the amplifier is mounted directly to a solid aluminum heat exchanger to reduce the need for moving parts and increase long-term reliability. Lastly, the input circuit's low-distortion operation and advanced safety limiter ensure that your signal's character remains true to the source at all volume levels.

Cutting-edge FiRPHASE technology

To ensure the highest quality of sound possible, the RCF NX 915-SMA harnesses the power of FIR (Finite Impulse Response) to allow for 0-degree linear phase playback. It's a highly advanced system that allows for an exceptionally coherent sound distribution to the entire audience, with no phase distortion and minimal latency. Astounding clarity, maximum transparency, and picture-perfect imaging: RCF's FiRPHASE technology is all but guaranteed to elevate and refine the sound of your system.

Innovative Bass Motion Control

In lieu of a typical highpass filter, RCF's engineers have outfitted the NX 915-SMA with a forward-thinking tone-shaping system called Bass Motion Control for enhanced low-end performance. In a nutshell, it's an advanced form of woofer excursion management that can handle even the lowest of audible frequencies with maximum woofer stability, clarity, and definition. How does it work? BMC functions by creating a total map of the woofer's behavior and then generating a custom algorithm that only limits over excursions. This results in a greatly enhanced low-register performance that does not change phase behavior in the slightest.
