Short answer: these RCF KX 45-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 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 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 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 low-quality vendor measurement is truncated and cannot produce a reliable preference score.
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 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.

RCF ART 715-A MK4: $500.00 B&H Photo Video Guitar Center eBay
Pros: 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.
Cons: The low-quality vendor measurement is truncated and cannot produce a reliable preference score. This discontinued MK4 offers little reason to choose it over the newer ART 715-A MK5 unless the used price is substantially lower.
