Short answer: these RCF NX 912-A and RCF ART 732-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 732-A MK4 is discontinued; its replacement is the RCF ART 732-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 732-A MK4. Its large 3-inch compression-driver voice coil, 131dB claimed peak and roughly 53Hz measured extension give it useful vocal headroom and more bass reach than the 712 MK4. The 39.2 lbs (17.8 kg) enclosure remains easy to carry.
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 data is truncated and does not yield a preference score. It is discontinued, lacks modern remote control and is eclipsed by the better-supported ART 732-A MK5 and current 9-series models.
Buy the RCF NX 912-A when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 732-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.
