Short answer: the FBT Mitus 115A. It ranks #19 of 62 15-inch pa speakers by sound quality, rated 3.7/5, at $1,790. The HK Audio Linear 5 MK2 115 FA ranks #27, rated 3.6/5, at $1,769.99, $20.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the FBT Mitus 115A: Medium-quality vendor data returns a 4.87 ideal-subwoofer preference score, continuing the FBT Mitus 112A’s B&C neodymium woofer and rotatable horn design in a 15-inch cabinet aimed at premium main-speaker use. The tradeoff: The measured bass extension (roughly 92Hz) is shallower than most 15-inch rivals here, and at a roughly $1790 asking price it is one of the more expensive boxes in this ranking.
The case for the HK Audio Linear 5 MK2 115 FA: Part of HK Audio’s LINEAR 5 MK II series alongside the HK Audio Linear 5 MK2 112 FA: the 15-inch full-range model, with bass to 54Hz (-10dB) and the highest output of the series. Watch for: No independent measurements yet, so it can’t be compared with ranked PA speakers.
Buy the FBT Mitus 115A. It is rated higher for sound quality, and saving $20.01 with the HK Audio Linear 5 MK2 115 FA does not make up for the sound-quality gap.
Worth knowing: the HK Audio Linear 5 MK2 115 FA has not been measured yet. Its rating is estimated from related models, with a likely range of 3.2 to 4.0, so treat this verdict as provisional.
