Short answer: the Yamaha DZR315. It ranks #16 of 38 15-inch pa speakers by sound quality, rated 3.8/5, at $1,829.99. The FBT Mitus 115A ranks #18, rated 3.7/5, at $1,790, $39.99 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Yamaha DZR315: A 3-way design with a 15-inch woofer, 8-inch midrange and 2-inch compression driver, powered by a 2000W bi-amp and rated to 143dB, so it covers a large room on its own. Watch for: A 4.4dB reference band and a 7.19 directivity-index deviation mean tonal balance and off-axis consistency are uneven, and the standalone preference score is only 1.93.
The case for the FBT Mitus 115A: Medium-quality vendor data returns a 4.87 ideal-subwoofer preference score, continuing the Mitus 112A’s B&C neodymium woofer and rotatable horn design in a 15-inch cabinet aimed at premium main-speaker use. Watch for: 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.
Buy the Yamaha DZR315. It is rated higher for sound quality, and saving $39.99 with the FBT Mitus 115A does not make up for the sound-quality gap.

Yamaha DZR315: $1,829.99 B&H Photo Video eBay
Pros: A 3-way design with a 15-inch woofer, 8-inch midrange and 2-inch compression driver, powered by a 2000W bi-amp and rated to 143dB, so it covers a large room on its own. Manufacturer measurements give a 5.06 preference score with an ideal subwoofer, and bass reaches 82.5Hz at -3dB and about 65Hz at -10dB. Onboard FIR DSP with an LCD screen handles presets, PEQ, delay and routing, with two combo inputs. Measured bass extension of 82.5Hz (-3dB).
Cons: A 4.4dB reference band and a 7.19 directivity-index deviation mean tonal balance and off-axis consistency are uneven, and the standalone preference score is only 1.93. It is large and expensive next to the 2-way DZR15.
