Short answer: choose between the JBL PRX912 and RCF ART 732-A MK4 for the requirements of the venue and system, not from rank alone. In this size class, coverage, bass extension, output capability, DSP, cabinet construction, and service support often decide the better fit. The RCF ART 732-A MK4 is discontinued; its replacement is the RCF ART 732-A MK5.
Why choose the JBL PRX912. High-quality manufacturer Spinorama data, 132dB claimed peak output, app control and unusually deep onboard processing make this one of the most versatile choices. The measured 54Hz bass extension is useful for speech and lighter music without a subwoofer.
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. Its 6.05 ideal-subwoofer preference score trails the QSC and FBT ProMaxX, with less even sound-power behavior in the supplied data. At 43 lbs (19.5 kg) it is not especially light, and Bluetooth is for control rather than audio streaming. 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 JBL PRX912 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.
