Active PA Speaker RCF NX 945-A

The RCF NX 945-A is a powerful two-way active system designed for the most demanding live sound, touring, and rental applications. Equipped with a 2100 W Class D bi-amping amplifier, this system delivers impressive sound pressure levels of up to 135 dB without distortion across its operating range of 45 Hz to 20 kHz. This performance makes the NX 945-A an effective solution for both front-of-house (FOH) and monitoring, suspended or satellite configurations.

At the heart of the system is a high-frequency compression driver with a 4-inch titanium voice coil and neodymium magnet, which guarantees clear and accurate reproduction of mid and high frequencies even in large venues. It is complemented by a 15-inch neodymium woofer with a 3.5-inch voice coil — a lightweight yet extremely powerful component that accurately reproduces dynamic bass with minimal distortion.

DSP processing technologies include the proprietary FiRPHASE phase correction system and the Bass Motion Control algorithm, which controls the woofer's excursion, maintaining sound linearity even at peak loads. Wide coverage of 100° × 70° is achieved thanks to the True Resistive Waveguide. The sturdy plywood enclosure is complemented by six M10 mounting points and four Quick Lock slots for flexible mounting.
