Short answer: choose between the Yamaha DXR15mkIII and RCF NX 915-A 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 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.
Why choose the RCF NX 915-A. The plywood enclosure, FiRPHASE/Bass Motion Control processing and flexible rigging make it a sturdier systems alternative to the ART 715-A MK5, with a wide 100° x 60° pattern and 131dB claimed peak.
What to weigh before buying. 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. The truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders. At 53.1 lbs (24.1 kg) it is notably heavier than the ART-series alternatives.
Buy the Yamaha DXR15mkIII when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF NX 915-A 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.
