Short answer: the QSC K12.2, with the ProMaxX 112A as a strong value alternative when it is available locally. These rank #1 and #3 out of 37 12-inch powered PA speakers, and both post strong measured results for the size class.
The K12.2 measures slightly ahead, with a deeper bass extension. Its low-quality vendor data returns a 6.82 ideal-subwoofer preference score with 48Hz measured extension. The ProMaxX 112A’s medium-quality data returns a close 6.30 score, second only to the K12.2 among the scored mainstream models here, with a shallower 68Hz extension. Its own review notes it needs a subwoofer sooner than most 12-inch competitors as a result.
Distribution and long-term support favor the QSC. The K12.2 benefits from extensive onboard DSP and a long market track record. The ProMaxX 112A’s own review flags that distribution and service availability are less universal than QSC, JBL, Yamaha or RCF, even though its smooth tonal result and high-output PA format make it a compelling value when it is available.
Both are conventional 2-way bass-reflex 12-inch actives with a 90 degree x 60 degree coverage pattern on the ProMaxX and a narrower 75 degree conical pattern on the K12.2.
Buy the QSC K12.2 for the higher measured preference score, deeper bass extension, and QSC’s wide dealer and service network.
Buy the FBT ProMaxX 112A if you can find one locally and want nearly the same measured performance, often at a lower price.

QSC K12.2: $899.99 Amazon B&H Photo Video Guitar Center eBay
Pros: The strongest all-round tonal result in this popular-model group: the vendor Spinorama data produces a 6.82 ideal-subwoofer preference score and 48Hz measured bass extension. Extensive onboard DSP, flexible main/monitor use and a long market track record make it an unusually safe general-purpose choice.
Cons: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution. It is not the cheapest 12-inch option, and serious dance music or high-output live use still benefits from a subwoofer.
