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. The RCF ART 712-A MK4 is discontinued; its replacement is the RCF ART 712-A MK5.
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 39.2 lbs (17.8 kg) 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.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
