Short answer: choose between the JBL PRX912 and RCF NX 932-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 NX 932-A. A 3-inch titanium compression-driver diaphragm, 100° x 70° coverage and plywood cabinet make it especially capable for clear vocals over wide areas. The 2100W amplifier, advanced RCF processing and 132dB peak claim support serious main-speaker use.
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 medium-quality Spinorama measurement is truncated and cannot generate a preference score, so its high position relies partly on response/directivity curves and published engineering. At 50.5 lbs (22.9 kg) it is significantly heavier than the ART 932-A.
Buy the JBL PRX912 when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF NX 932-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.
