RCF NX 945-A vs Yamaha DBR15

Short answer: choose between the RCF NX 945-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 945-A. The top NX-series 15-inch box pairs a plywood cabinet with a 135dB claimed peak, the highest in the NX range, and a wide 100° x 70° pattern. RCF’s FiRPHASE and Bass Motion Control processing carry over from the smaller NX models.

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 measurement is truncated and does not produce a preference score, so its tonal position relies on published engineering rather than a confirmed result. At 60.2 lbs (27.3 kg) it is heavier than the ART 945-A alternative. 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 945-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.
