Short answer: the Martin Audio CDD15. It ranks #31 of 38 15-inch pa speakers by sound quality (rated 3.3/5); the DAS Audio Vantec 15A ranks #34 (rated 3.1/5).
What the Martin Audio CDD15 does well: 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 tradeoff: 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 DAS Audio Vantec 15A: Medium-quality vendor data shows 52Hz measured extension, and its 90° x 50° coverage and 135dB claimed peak carry over the DAS Audio Vantec 12A’s Class-D amplification and Bluetooth control into a 15-inch cabinet. The tradeoff: The 2.87 ideal-subwoofer preference score is one of the lower results in this ranking, well below the DAS Audio Vantec 12A’s own measured result.

The Two Speakers In Full
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.
