RCF NX 945-A Active Speaker
The NX 945-A is the top two-way box in the wide-coverage NX-A range, pairing a 15-inch neodymium woofer with a 4-inch titanium/neodymium compression driver on a 1.4-inch voice coil. The 2100W Class-D bi-amp (1400W LF, 700W HF) reaches 135 dB SPL across a 100 by 70 degree pattern with a 45 Hz to 20 kHz response, built for sound providers, small bands and DJs who need serious headroom from one cabinet.
FiRPHASE and Bass Motion Control DSP hold the response flat and the phase coherent through the 650 Hz crossover, and a soft limiter protects the drivers at full output. The plywood cabinet ships in black or white with PowerCON TRUE1 TOP power in/out and a combo XLR/jack input, and works stand-alone, as a satellite with a sub, as a stage monitor, or flown.
