Short answer: choose between the JBL PRX912 and RCF HD 12-A MK5 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.
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 HD 12-A MK5. Medium-quality vendor data indicates useful extension into the low 60Hz region.
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 truncated Spinorama measurement cannot produce a preference score, so tonal confidence is lower than for the fully scored leaders. Controls are intentionally simple and omit app control, networking and a multi-input mixer.
Buy the JBL PRX912 when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF HD 12-A MK5 when its stated strengths are the better match for the room and the rest of the PA.
Skip the RCF HD 12-A MK5 if sound quality matters to you. It ranks near the bottom of the 37 12-inch two-way powered pa speakers.

RCF HD 12-A MK5: $600.00 B&H Photo Video Guitar Center eBay
Pros: The current 18.3kg cabinet offers 130dB claimed peak output, 90° x 60° coverage and RCF FiRPHASE/Bass Motion Control processing at a comparatively accessible price. Medium-quality vendor data indicates useful extension into the low 60Hz region.
Cons: The truncated Spinorama measurement cannot produce a preference score, so tonal confidence is lower than for the fully scored leaders. Controls are intentionally simple and omit app control, networking and a multi-input mixer.
