Short answer: choose between the RCF NX 915-A and Yamaha DBR15 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 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.
Why choose the Yamaha DBR15. Yamaha’s most portable 15-inch powered speaker carries the same DSP and amplification platform as the DXR and DZR series, with a built-in 2-channel mixer accepting XLR, 1/4-inch, RCA and 3.5mm sources.
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 53.1 lbs (24.1 kg) it is notably heavier than the ART-series alternatives. Medium-quality vendor data shows a 2.87 ideal-subwoofer preference score, one of the weaker results in this ranking and well below the DBR12’s own measured result, so a subwoofer partner matters more here than with most alternatives.
Buy the RCF NX 915-A when its stated coverage, output, processing, and deployment format best match the job.
Buy the Yamaha DBR15 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.
