#39 MartinLogan Depth 215: $6,999.99 Estimated MartinLogan eBay
Same family: the MartinLogan Depth 212 (smaller subwoofer, ranked lower, estimated 4.1/5).
Pros: The flagship of MartinLogan’s Depth series: two opposed 15” Carbon Aerocore woofers in a force-cancelling sealed cabinet with a 4400W peak amplifier, rated 18 to 120Hz (±3dB), with app control and Anthem Room Correction.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from MartinLogan’s measured subs, the best of which, the single-15” Dynamo 1600X, reached 120.5dB in the 40 to 80Hz CEA-2010 bands. Two opposed 15” drivers and 4400W peak should go beyond that. It weighs 78.5kg.
