Short answer: choose between the RCF NX 912-A and Yamaha DXR15mkIII 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 RCF NX 912-A. The plywood enclosure, 2100W amplification, FiRPHASE/Bass Motion Control and flexible rigging make it a sturdier systems alternative to the ART 912-A. Medium-quality data indicates extension to roughly 58Hz with broad 100° x 60° coverage.
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 truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders. Its 130dB peak claim matches the cheaper ART 912-A rather than exceeding it. 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 912-A when its stated coverage, output, processing, and installation format fit the job better.
Buy the Yamaha DXR15mkIII 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.
