RCF NX 945-A vs RCF NX 915-A

Last updated: September 7, 2026

Short answer: these RCF NX 945-A and RCF NX 915-A 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 NX 915-A. The plywood enclosure, FiRPHASE/Bass Motion Control processing and flexible rigging make it a sturdier systems alternative to the ART 715-A MK5, with a wide 100° x 60° pattern and 131dB claimed peak.

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 truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders. At 24.1kg it is notably heavier than the ART-series alternatives.

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

Buy the RCF NX 915-A when its stated strengths are the better match for the room and the rest of the PA.
