Short answer: choose between the Yamaha DZR12 and RCF NX 945-A 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.
Why choose the Yamaha DZR12. Premium cabinet construction, 139dB claimed output and deep onboard 96kHz DSP suit demanding live work. The local vendor data shows useful 48Hz measured extension, the deepest result among the scored Yamaha models here.
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.
What to weigh before buying. It is heavy at roughly 21kg and has no Bluetooth audio. 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 27.3kg it is heavier than the ART 945-A alternative.
Buy the Yamaha DZR12 when its stated coverage, output, processing, and installation format fit the job better.
Buy the RCF NX 945-A when its stated strengths better suit the venue and the rest of the system.

Yamaha DZR12: $1,198.49 Amazon B&H Photo Video Guitar Center eBay
Pros: Premium cabinet construction, 139dB claimed output and deep onboard 96kHz DSP suit demanding live work. The local vendor data shows useful 48Hz measured extension, the deepest result among the scored Yamaha models here.
Cons: Its medium-quality vendor measurement produces only a 4.22 ideal-subwoofer preference score, so the price buys output, processing and build more than neutral tonality. It is heavy at roughly 21kg and has no Bluetooth audio.
