RCF NX 945-A vs RCF ART 715-A MK4

Short answer: these RCF NX 945-A and RCF ART 715-A MK4 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 715-A MK4. The 19.6kg cabinet combines 130dB claimed peak output, a broad horn and RCF’s FiRPHASE processing in a straightforward, affordable package for a 15-inch box.

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 produce a reliable preference score.

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

Buy the RCF ART 715-A MK4 when its stated strengths are the better match for the room and the rest of the PA.

If sound quality matters at all to you, skip the RCF ART 715-A MK4. It ranks near the bottom of the 29 15-inch two-way powered pa speakers, so look higher up the list instead.
