Yamaha DXR8mkII vs RCF NX 945-A

Short answer: choose between the Yamaha DXR8mkII and RCF NX 945-A by matching the speaker to the deployment rather than treating their ranking positions as a universal verdict. Coverage, cabinet format, bass extension, output capability, DSP, and service support all matter in a PA system.

Why choose the Yamaha DXR8mkII. Medium-quality vendor data shows a 5.89 ideal-subwoofer preference score with 64Hz measured extension, among the strongest results here. Yamaha’s FIR-X processing, a 1.75-inch neodymium compression driver and a 90° x 60° constant-directivity horn carry over the larger DXR models’ engineering into a compact cabinet.

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.

What to weigh before buying. No mkIII successor exists for this size yet, so it is the oldest design generation in this ranking’s Yamaha lineup, without app control or Bluetooth audio. 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 60.2 lbs (27.3 kg) it is heavier than the ART 945-A alternative.

Buy the Yamaha DXR8mkII when its stated coverage, output, processing, and installation format fit the job better.

Buy the RCF NX 945-A when its stated strengths better suit the venue and the rest of the system.

Frequency Response Compared

Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
