Short answer: choose between the JBL PRX912 and Yamaha DXR12mkII 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 Yamaha DXR12mkII is discontinued; its replacement is the Yamaha DXR12mkIII.
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 Yamaha DXR12mkII. A proven, broadly distributed workhorse with a flexible three-channel input section and 134dB claimed maximum output. Medium-quality vendor Spinorama data and 61Hz measured extension provide more evidence than many PA competitors, while Yamaha’s FIR-X processing and D-CONTOUR presets simplify setup.
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 5.49 ideal-subwoofer preference score is only mid-pack, with meaningful response/directivity irregularity in the supplied data. It lacks app control and Bluetooth audio, and newer competitors offer more user-adjustable DSP.
Buy the JBL PRX912 when its stated coverage, output, processing, and deployment format best match the job.
Buy the Yamaha DXR12mkII 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.
