Short answer: choose between the JBL PRX912 and RCF ART 712-A MK4 by matching the speaker to the deployment rather than treating their ranking positions as a universal verdict. Coverage, cabinet format, bass extension, output capability, DSP, and service support all matter in a PA system.
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 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. Its 5.16 ideal-subwoofer preference score trails the QSC and FBT ProMaxX, with less even sound-power behavior in the supplied data. At 19.5kg it is not especially light, and Bluetooth is for control rather than audio streaming. The low-quality vendor measurement is truncated and cannot produce a reliable preference score.
Buy the JBL PRX912 when its stated coverage, output, processing, and installation format fit the job better.
Buy the RCF ART 712-A MK4 when its stated strengths better suit the venue and the rest of the system.
If sound quality matters at all to you, skip the RCF ART 712-A MK4. It ranks near the bottom of the 37 12-inch two-way powered pa speakers, so look higher up the list instead.

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.
