Short answer: the L-Acoustics X12. It ranks #3 of 50 12-inch pa speakers by sound quality (rated 4.6/5); the FBT ProMaxX 112A ranks #4 (rated 4.5/5).
Why pick the L-Acoustics X12: Vendor Spinorama data gives the highest preference scores in the 12-inch ranking: 5.60 standalone and 8.52 with an ideal subwoofer. The tradeoff: 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.
Why pick the FBT ProMaxX 112A: Medium-quality vendor data yields a strong 7.21 ideal-subwoofer preference score, second only to the QSC among the scored mainstream models here. The catch: Measured bass extension is only 68Hz, so it needs a subwoofer sooner than most 12-inch competitors.

L-Acoustics X12 Passive eBay
Pros: Vendor Spinorama data gives the highest preference scores in the 12-inch ranking: 5.60 standalone and 8.52 with an ideal subwoofer. The listening-window response is very even (narrow-band deviation 0.158) and predicted in-room smoothness is 0.853, so tone stays consistent across the 90° x 60° coverage. Bass reaches about 78Hz (-3dB) in a 20kg coaxial cabinet with a 136dB maximum SPL. Measured bass extension of 78Hz (-3dB).
Cons: 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. Bass extension of about 78Hz (-3dB) is modest for a 12-inch box, and a subwoofer is needed for full-range music. Pricing is dealer quoted and typically well above self-powered 12-inch alternatives once the controller is included.

FBT ProMaxX 112A: $722 Thomann eBay
Pros: Medium-quality vendor data yields a strong 7.21 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. Measured bass extension of 68Hz (-3dB).
Cons: 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.
