Short answer: choose between the RCF ART 745-A MK4 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 ART 745-A MK4. The largest ART7 compression driver, 133dB claimed peak and a light 18.8kg enclosure give this discontinued flagship useful vocal headroom for a 15-inch box.
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 low-quality vendor data is truncated and does not yield a preference score. It is discontinued and is eclipsed by the better-supported ART 745-A MK5. Medium-quality vendor data shows a 2.43 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 ART 745-A MK4 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.
The Yamaha DBR15 is not a sound-quality pick. It sits near the bottom of the 29 15-inch two-way powered pa speakers; there are better options higher up.
