Short answer: choose between the RCF NX 945-A and Yamaha DXR15mkIII 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 DXR15mkIII. The third-generation DXR15 raises claimed output to 134dB with 2000W amplification, app-based control and Yamaha’s newest onboard DSP, while its 90° x 60° pattern matches the well-regarded DXR12mkIII.
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 60.2 lbs (27.3 kg) it is heavier than the ART 945-A alternative. The low-quality local data is truncated and cannot produce a preference score, so its tonal advantage over the proven DXR15mkII is unconfirmed. Wireless connectivity is for remote control, not audio streaming.
Buy the RCF NX 945-A when its stated coverage, output, processing, and deployment format best match the job.
Buy the Yamaha DXR15mkIII when its stated strengths are the better match for the room and the rest of the PA.

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.
