RCF NX915-SMA Active 2100W 15-Inch 2-Way High Output Stage Monitor

RCF NX915-SMA Active 2100W 15-Inch 2-Way High Output Stage Monitor

The RCF NX 915-SMA is a high-performance 15" active stage monitor designed for touring, portable PA, and FRFR applications. With 2100W Class-D bi-amplification, upgraded transducers, and advanced DSP including FiRPHASE and Bass Motion Control, it delivers up to 131 dB of clear, powerful sound with extended low end and pinpoint clarity. Equally at home as a floor wedge or a main PA on a pole, the NX 915-SMA is built to meet the demands of sound providers, bands, DJs, and modern modeler-based guitar rigs.

• Up to 131 dB maximum SPL with wide, even coverage
• 2100W Class-D bi-amplification (1400W LF + 700W HF peak)
• 45 Hz – 20 kHz linear frequency response
• 1.75" compression driver (1" exit) with redesigned phase plug for greater clarity
• 15" woofer with 2.5" voice coil and extended low-frequency performance
• FiRPHASE zero-degree phase DSP for transparent sound and precise imaging
• Bass Motion Control (BMC) woofer excursion management for deep, controlled bass without phase-smearing HPFs
• 100° x 70° True Resistive Waveguide (TRW) constant directivity coverage
• Perfectly tailored for both horizontal (wedge) and vertical (main PA) deployment
• FRFR (Full Range Flat Response) voicing ideal for amp/modeler rigs
• Tour-ready, rugged all-wood cabinet with steel grille and integrated handles
• True Outdoor Protection (TOP) PowerCON TRUE1 IN/OUT power connectors

Designed as a premium stage monitor, the NX 915-SMA combines a 1.75" compression driver, 15" woofer, and a powerful 2-channel 2100W Class-D amplifier to deliver coherent 100° x 70° coverage with impressive headroom and low distortion. Used as a wedge, stand-mounted top, or satellite over a subwoofer, it provides the flexibility needed for modern live sound.

RCF’s FiRPHASE processing ensures linear phase response for natural, time-aligned sound across the entire listening area, while Bass Motion Control precisely manages woofer excursion for extended low-frequency performance without sacrificing stability or clarity. The new True Resistive Waveguide (TRW) delivers a smooth, constant directivity pattern, acting like a single acoustic source with reduced HF distortion.

Built into a robust plywood cabinet with multiple rigging points, pole mount, and integrated handles, the NX 915-SMA is a proven workhorse for touring rigs, rental houses, and fixed installations. Its FRFR response makes it a perfect partner for multi-FX and amp modelers, serving as both a guitar/bass cabinet and a stage monitor with the power and fidelity to handle any performance.
