Brand: FBT
#14 FBT Promaxx 114A: $1,775.00 Full Compass $1,775.00 eBay
Same family: the FBT ProMaxX 110A (smaller model, rated 4.1/5) and the FBT ProMaxX 112A (smaller model, rated 4.5/5).
Pros: A light powered PA speaker with good sound, loud peaks and three built in monitor angles for floor use. Vendor Spinorama data gives preference scores of 4.09 standalone and 7.12 with an ideal subwoofer. The 14-inch woofer and 700W amplifier claim 135.5dB peak output from an 18.8kg polypropylene cabinet, and three built-in monitor angles cover floor use. Measured bass extension of 88Hz (-3dB).
Cons: 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. Listening-window narrow-band deviation is 0.393, less even than the best boxes in this ranking, and the non-standard 14-inch size means fewer matching accessories.
