Short answer: the PRX912 for most buyers, the EX12 if the price and weight are not obstacles. These rank #4 and #5 of 37 12-inch powered PA speakers, priced $2481 apart.
The EX12 measures ahead on the numbers that matter most. Its vendor data shows a 5.83 ideal-subwoofer preference score with 60Hz measured extension, one of the strongest results in this size class, from a 3-inch-diaphragm compression driver on an 80° x 40° horn claiming 133dB peak. The PRX912’s own data still lands respectably at 5.16 with 54Hz extension, but its own cons note less even sound-power behavior than the class leaders, trailing the EX12 here.
The PRX912 wins on everyday usability. It has JBL Pro Connect app control and deep onboard DSP, useful for tuning and monitoring from a phone, while the EX12 has no onboard mixer, app control or general-purpose parametric EQ, just integrated crossover, phase alignment, EQ and protection with no user-facing adjustment beyond that. The PRX912 is also considerably lighter at 19.5kg against the EX12’s 27.4kg, and its narrower 90° x 50° coverage compares with the EX12’s tighter 80° x 40° horn built for controlled throw.
Buy the PRX912 if you want app control, easier handling, and a still-strong (if not class-leading) measured result at a lower price.
Buy the EX12 if you want the deepest measured performance in this size class and do not mind the heavier cabinet and premium price.

The Two Speakers In Full
KV2 Audio EX12: $3,480.00 eBay
Pros: A 5.83 ideal-subwoofer preference score and 52Hz bass extension from medium-quality vendor data make this one of the strongest measured specialist boxes. Its 3-inch-diaphragm compression driver, 133dB claimed peak and 80° x 40° horn target high vocal clarity and controlled throw.
Cons: The 27.4kg enclosure and premium price make it much less portable and accessible than the mainstream leaders. User controls are comparatively spare, without an onboard mixer, app control or general-purpose parametric EQ.

JBL PRX912: $999.00 Amazon B&H Photo Video Guitar Center eBay
Pros: 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.
Cons: 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.
