Short answer: these RCF KX 32-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 KX 32-A. A 3200W amplifier, 3-inch titanium-dome compression driver, RDNet control and 134dB claimed peak output make this the most ambitious current RCF 12-inch point source here. Medium-quality data shows smooth core-band behavior and extension into the low 60Hz region.
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 measurement is truncated and cannot produce a preference score, while the 52 lbs (23.6 kg) plywood enclosure is heavier than mainstream molded alternatives. Pricing and broad retail availability are not yet established. 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 KX 32-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.
