Short answer: choose between the JBL PRX912 and RCF ART 912-A 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 ART 912-A. A current, widely stocked 12-inch RCF with 130dB claimed output, 100° x 60° coverage and the same FiRPHASE/Bass Motion Control platform used higher in the ART 9 line. It is a straightforward choice for users who value simple setup over menu-heavy DSP.
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 available low-quality manufacturer directivity data has no computed preference score, limiting confidence in cross-brand tonal comparisons. It has only basic rear-panel presets and no wireless control or Bluetooth audio.
Buy the JBL PRX912 when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 912-A 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.
