Short answer: the Martin Audio CDD15. It ranks #31 of 38 15-inch pa speakers by sound quality (rated 3.3/5); the Martin Audio XP15 ranks #32 (rated 3.2/5).
The case for the Martin Audio CDD15: A 15-inch woofer with a coaxial 1.4-inch titanium compression driver uses Coaxial Differential Dispersion, widening coverage from 60° far away to 100° up close for even level across a room. The catch: A wide 4.9dB reference band and 0.701 listening-window deviation mean tonal balance is uneven, with a 1.99 standalone score.
Why pick the Martin Audio XP15: Medium-quality vendor data returns a 4.71 ideal-subwoofer preference score with 48Hz measured extension, extending the XP12’s rotatable horn and Class-D amplification to a 15-inch cabinet. The tradeoff: Martin Audio has a smaller North American dealer network than JBL, Yamaha or QSC, and pricing is not yet well established for this model.

Martin Audio CDD15 Passive eBay
Pros: A 15-inch woofer with a coaxial 1.4-inch titanium compression driver uses Coaxial Differential Dispersion, widening coverage from 60° far away to 100° up close for even level across a room. Bass reaches 80Hz at -3dB and about 50Hz at -10dB, and manufacturer measurements give a 4.91 preference score with an ideal subwoofer. Measured bass extension of 80Hz (-3dB).
Cons: A wide 4.9dB reference band and 0.701 listening-window deviation mean tonal balance is uneven, with a 1.99 standalone score. It is a 26kg passive install cabinet that needs Martin Audio amplification and presets, and it is sold only through dealers.
