Short answer: choose between the RCF NX 910-A and Yamaha DXR15mkII 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. The Yamaha DXR15mkII is discontinued; its replacement is the Yamaha DXR15mkIII.
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 DXR15mkII. A proven, broadly distributed workhorse: medium-quality vendor data shows a 4.98 ideal-subwoofer preference score with 61Hz measured extension, and Yamaha’s FIR-X processing and D-CONTOUR presets simplify setup.
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 preference score sits mid-pack for this ranking, and it lacks app control or Bluetooth audio found on some newer competitors.
Buy the RCF NX 910-A when its stated coverage, output, processing, and installation format fit the job better.
Buy the Yamaha DXR15mkII 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.
