Short answer: the DXR15mkIII for most buyers, the Mitus 115A if you specifically want its B&C driver and rotatable horn. These rank #20 and #25 of 76 15-inch powered PA speakers, priced $690.01 apart.
Neither has a fully confirmed preference score, but for different reasons. The DXR15mkIII’s low-quality local data is truncated and cannot produce a preference score, so its tonal advantage over the proven DXR15mkII is unconfirmed, even with claimed output raised to 134dB and 2000W amplification. The Mitus 115A does have a computed score, 4.15 from medium-quality vendor data, but its own cons note the measured bass extension of roughly 92Hz is shallower than most 15-inch rivals despite a roughly $1,790 asking price, one of the more expensive boxes in this size class.
The DXR15mkIII adds modern convenience the Mitus 115A skips. It has Bluetooth 5.0 audio streaming and D-Remote control alongside Yamaha’s FIR-X tuning and Drive Motion Calibration, while the Mitus 115A’s connectivity is a plain XLR input with link output and no wireless features at all. The Mitus 115A does continue the Mitus line’s B&C neodymium woofer and rotatable horn design, aimed at premium main-speaker use.
Buy the DXR15mkIII if you want Bluetooth audio streaming, app-based remote control, and the lower price.
Buy the Mitus 115A if the B&C neodymium woofer and rotatable horn design matter more to you than confirmed measured bass extension.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
