Short answer: choose between the FBT ProMaxX 112A 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 FBT ProMaxX 112A. Medium-quality vendor data yields a strong 6.30 ideal-subwoofer preference score, second only to the QSC among the scored mainstream models here. Its smooth tonal result and high-output PA format make it a compelling value when it is available locally.
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. Measured bass extension is only 68Hz, so it needs a subwoofer sooner than most 12-inch competitors. Distribution and service availability are less universal than QSC, JBL, Yamaha or RCF. 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.
Buy the FBT ProMaxX 112A 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.
