Short answer: the L-Acoustics X12 for better sound quality, the FBT ProMaxX 112A for the lower price. The L-Acoustics X12 ranks #3 of 83 12-inch pa speakers, rated 4.6/5, at $3,170. The FBT ProMaxX 112A ranks #4, rated 4.5/5, at $722, $2,448 cheaper.
The L-Acoustics X12 is the more accurate option. An excellent sounding 12 inch PA speaker, a passive coaxial cabinet with highly accurate, consistent sound across its whole coverage area. Its measured preference score, a predictor of how neutral it sounds, is 5.60 against 4.30 for the FBT ProMaxX 112A. The catch: This is a passive cabinet that needs an L-Acoustics amplified controller such as the LA4X or LA12X, so the box alone will not play.
The FBT ProMaxX 112A is the deeper-bass pick. An excellent sounding 12 inch powered PA speaker, with smooth, accurate tone and high output at a great price. Its bass reaches about 68Hz before falling 3dB, against 78Hz for the L-Acoustics X12. The tradeoff: Measured bass extension is only 68Hz, so it needs a subwoofer sooner than most 12-inch competitors.
Buy the L-Acoustics X12 if sound quality is the priority over the price, or the FBT ProMaxX 112A if the price is the priority over sound quality.
