RCF NX 945-A vs Yamaha DXR15mkII

Short answer: choose between the RCF NX 945-A and Yamaha DXR15mkII for the requirements of the venue and system, not from rank alone. In this size class, coverage, bass extension, output capability, DSP, cabinet construction, and service support often decide the better fit.

Why choose the RCF NX 945-A. The top NX-series 15-inch box pairs a plywood cabinet with a 135dB claimed peak, the highest in the NX range, and a wide 100° x 70° pattern. RCF’s FiRPHASE and Bass Motion Control processing carry over from the smaller NX models.

Why choose the Yamaha DXR15mkII. A proven, broadly distributed workhorse: medium-quality vendor data shows a 4.37 ideal-subwoofer preference score with 61Hz measured extension, and Yamaha’s FIR-X processing and D-CONTOUR presets simplify setup.

What to weigh before buying. The measurement is truncated and does not produce a preference score, so its tonal position relies on published engineering rather than a confirmed result. At 27.3kg it is heavier than the ART 945-A alternative. The preference score sits mid-pack for this ranking, and it lacks app control or Bluetooth audio found on some newer competitors.

Buy the RCF NX 945-A when its stated coverage, output, processing, and deployment format best match the job.

Buy the Yamaha DXR15mkII when its stated strengths are the better match for the room and the rest of the PA.
