Short answer: the Turbosound NuQ152. It ranks #17 of 38 15-inch pa speakers by sound quality (rated 3.7/5); the Amate Audio X14FD ranks #24 (rated 3.6/5).
The case for the Turbosound NuQ152: Vendor Spinorama data gives preference scores of 3.99 standalone and 6.59 with an ideal subwoofer, and bass reaches about 65Hz (-3dB), deeper than most boxes on this ranking. Watch for: The Spinorama data is low quality, so the measured curves should be treated cautiously.
What the Amate Audio X14FD does well: A 14-inch coaxial design that reaches 65Hz at -3dB and about 55Hz at -10dB, with a 2.4dB reference band that keeps the midrange and treble fairly even. The catch: A 0.687 listening-window deviation means tonal balance is less even than the best 15-inch picks, and the standalone score is 2.38.

Pros: Vendor Spinorama data gives preference scores of 3.99 standalone and 6.59 with an ideal subwoofer, and bass reaches about 65Hz (-3dB), deeper than most boxes on this ranking. Sensitivity of 97dB means modest amplifiers reach high levels, and the 70° pattern is easy to place. Measured bass extension of 65Hz (-3dB).
Cons: The Spinorama data is low quality, so the measured curves should be treated cautiously. Predicted in-room smoothness of 0.438 is well behind the best 15-inch boxes, and as a passive cabinet it needs an external amplifier and processor to play at all.
