#31 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.
How it compares: Just above it: FBT J15A. Just below it: Martin Audio XP15.
