Short answer: choose between the RCF NX 910-A and Yamaha DZR15 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 910-A. The plywood enclosure and FiRPHASE/Bass Motion Control processing make it a sturdier systems alternative to the ART 710-A MK5, with a wide 100° x 60° pattern and 130dB claimed peak.
Why choose the Yamaha DZR15. Medium-quality vendor data returns a 5.25 ideal-subwoofer preference score with 39Hz measured extension, deeper than the DZR12. The bi-amped 2-inch compression driver and sophisticated onboard DSP target serious main-speaker duty.
What to weigh before buying. The truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders. At 36.2 lbs (16.4 kg) it is heavier than the ART-series alternative. The bass-extension figure comes from truncated manufacturer data and should be read cautiously.
Buy the RCF NX 910-A when its stated coverage, output, processing, and installation format fit the job better.
Buy the Yamaha DZR15 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.
