Short answer: these RCF ART 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 ART 945-A. This is the strongest-measuring 15-inch RCF here: medium-quality vendor data produces a 5.91 ideal-subwoofer preference score with roughly 50Hz extension. The top-tier compression driver and 18.8kg enclosure combine unusually high output with easy portability for a 15-inch box.
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. Pricing and wide retail distribution are not yet well established for this model, and the RCF ART9 range above the 912/932-A pair has a shorter market track record. Coverage and full connector details were not confirmed in local data. 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 ART 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.
