Short answer: the KV2 Audio EX15 if sound quality matters most, the FBT Promaxx 114A if price matters most. The KV2 Audio EX15 ranks #11 of 76 15-inch pa speakers, rated 4.0/5, at $6,000. The FBT Promaxx 114A ranks #14, rated 3.9/5, at $1,775, $4,225 cheaper.
The KV2 Audio EX15 is the deeper-bass option. A powered 15 inch PA speaker with very deep bass, good sound and DSP tuned for clear vocals over long throws. Its bass reaches about 50Hz before falling 3dB, against 88Hz for the FBT Promaxx 114A. The tradeoff: At a roughly $6000 asking price this specialist box is far less accessible than the mainstream leaders, and user controls are comparatively spare without an onboard mixer or app control.
The FBT Promaxx 114A is the more accurate choice. A light powered PA speaker with good sound, loud peaks and three built in monitor angles for floor use. Its measured preference score, a predictor of how neutral it sounds, is 4.09 against 2.82 for the KV2 Audio EX15. The tradeoff: Measured bass reaches only about 88Hz (-3dB) with a 73Hz ideal-subwoofer extension point, so it does not go as deep as the woofer size suggests.
Buy the KV2 Audio EX15 if sound quality is the priority over the price, or the FBT Promaxx 114A if the price is the priority over sound quality.
