Short answer: these RCF NX 912-A and RCF ART 712-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 912-A. The plywood enclosure, 2100W amplification, FiRPHASE/Bass Motion Control and flexible rigging make it a sturdier systems alternative to the ART 912-A. Medium-quality data indicates extension to roughly 58Hz with broad 100° x 60° coverage.
Why choose the RCF ART 712-A MK4. The 17.8kg cabinet combines 129dB claimed peak output, a broad horn and RCF’s FiRPHASE processing in a straightforward package. Its measured response extends to roughly 65Hz before the first major roll-off.
What to weigh before buying. The truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders. Its 130dB peak claim matches the cheaper ART 912-A rather than exceeding it. The low-quality vendor measurement is truncated and cannot produce a reliable preference score.
Buy the RCF NX 912-A when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 712-A MK4 when its stated strengths are the better match for the room and the rest of the PA.
The RCF ART 712-A MK4 is not a sound-quality pick. It sits near the bottom of the 37 12-inch two-way powered pa speakers; there are better options higher up.

Pros: The 17.8kg cabinet combines 129dB claimed peak output, a broad horn and RCF’s FiRPHASE processing in a straightforward package. Its measured response extends to roughly 65Hz before the first major roll-off.
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 712-A MK5 unless the used price is substantially lower.
