Short answer: choose between the Yamaha DXR15mkII 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. The Yamaha DXR15mkII is discontinued; its replacement is the Yamaha DXR15mkIII. If you are buying new, get the Yamaha DXR15mkIII.
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.
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 preference score sits mid-pack for this ranking, and it lacks app control or Bluetooth audio found on some newer competitors. 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 DXR15mkII 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.
