RCF KX 45-A vs RCF ART 715-A MK5

Short answer: these RCF KX 45-A and RCF ART 715-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 KX 45-A. RCF’s flagship 15-inch point source pairs a 3200W amplifier with a 3-inch titanium-dome compression driver, RDNet remote control and a 137dB claimed peak, the highest maximum-output claim in this ranking. Rotatable 100° x 70° coverage suits both main and monitor use.

Why choose the RCF ART 715-A MK5. A compact, affordable RCF with 130dB claimed output and FiRPHASE processing, extending the well-regarded ART 712-A MK5’s simple, subwoofer-paired design to a 15-inch woofer for deeper reach.

What to weigh before buying. The local measurement is truncated and cannot produce a preference score. At 28.4kg it is one of the heaviest boxes here, and pricing/retail availability are not yet established. The local low-quality manufacturer data has no computed preference score, making its measured tonal position uncertain. The smaller compression-driver assembly offers less vocal headroom than the ART 735-A MK5.

Buy the RCF KX 45-A when its stated coverage, output, processing, and deployment format best match the job.

Buy the RCF ART 715-A MK5 when its stated strengths are the better match for the room and the rest of the PA.
