Short answer: choose between the L-Acoustics 112P and JBL PRX912 for the deployment, not from the automatic ranking alone. Their driver format, power requirements, coverage, bass reach, output capability, and control features determine which is the more practical PA for a particular room or system.
The case for the L-Acoustics 112P. Its medium-quality vendor Spinorama data produces the category’s highest ideal-subwoofer preference score at 8.09, with 54Hz bass extension. The coaxial layout gives symmetric 90° coverage and strong feedback resistance for monitor and near-field work.
The case for 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.
Important trade-offs. This discontinued 70.5 lbs (32 kg) cabinet is difficult to source, very heavy for a portable 12-inch box and lacks modern networking or an onboard mixer. Its ranking reflects acoustic performance rather than present-day value or ownership convenience. 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.
Buy the L-Acoustics 112P when its stated format, coverage, and system features fit the job better.
Buy the JBL PRX912 when its stated output, control, and deployment strengths better match the system.

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.
