RCF NX 945-A vs RCF ART 745-A MK5

Short answer: these RCF NX 945-A and RCF ART 745-A MK5 alternatives share a brand and size class, but their coverage, driver architecture, cabinet format, processing, and output priorities can make them fit very different jobs.

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 RCF ART 745-A MK5. The top of the ART7 range pairs 133dB claimed peak output with a light 18.8kg enclosure, RCF’s largest ART7-tier compression driver and FiRPHASE processing carried over from the smaller 712/732-A MK5 models.

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 27.3kg it is heavier than the ART 945-A alternative. The low-quality vendor measurement is truncated and cannot generate a preference score, so its tonal position relies on published engineering rather than a confirmed result.

Buy the RCF NX 945-A when its stated coverage, output, processing, and deployment format best match the job.

Buy the RCF ART 745-A MK5 when its stated strengths are the better match for the room and the rest of the PA.
