Active PA Speaker RCF NX 915-A

The RCF NX 915-A is a high-performance two-way active loudspeaker designed for professional use in live sound, installations, and touring applications. Thanks to its 2100 W Class D amplifier, it delivers extremely powerful sound pressure up to 131 dB while maintaining high sound accuracy across the entire frequency range of 45 Hz to 20 kHz.

At the heart of the system is a 15-inch woofer with a 2.5-inch voice coil and a 1.75-inch compression driver, connected via a constant directivity waveguide with 100° × 60° coverage. This allows for uniform coverage with minimal distortion even at high volumes. The built-in DSP features exclusive FiRPHASE and Bass Motion Control technologies that optimize phase linearity and control the excursion of the low-frequency driver without losing detail or bass depth.

The enclosure is made of sturdy plywood, equipped with conveniently located handles, a 35 mm pole mount socket, and various mounting points for suspension or installation. Thanks to passive cooling, the amplifier operates quietly and reliably without the use of a fan, reducing the likelihood of breakdowns in harsh operating conditions.
