Short answer: the MartinLogan Dynamo Foundation 12. It ranks #33 of 70 subwoofers by sound quality, rated 3.4/5, at $639.99. The MartinLogan Dynamo Foundation 10 ranks #52, rated 3.1/5, at $479.99, $160 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the MartinLogan Dynamo Foundation 12 does well: A sealed 12” MartinLogan subwoofer with a 700W peak (350W continuous) Magnitude amplifier, rated 24 to 200Hz (±3dB), with app control, Anthem Room Correction support and XLR inputs, in a 29 lbs (13.2 kg) cabinet. Watch for: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Dynamo 12 (110.6dB in the 40 to 80Hz CEA-2010 bands), which has more amplifier power and an aluminum woofer, so it is placed below it.
Why pick the MartinLogan Dynamo Foundation 10: MartinLogan’s entry subwoofer: a sealed cabinet with a 10” polypropylene woofer and a 400W peak (200W continuous) Magnitude amplifier, rated 25 to 200Hz (±3dB). Watch for: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Dynamo 12 (110.6dB in the 40 to 80Hz CEA-2010 bands).
Buy the MartinLogan Dynamo Foundation 12. It is rated higher for sound quality, and the $160 saving on the MartinLogan Dynamo Foundation 10 is not enough to make up the difference.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: MartinLogan Dynamo Foundation 12 3.0 to 3.5; MartinLogan Dynamo Foundation 10 2.7 to 3.4). Treat this verdict as provisional.

Same family: the MartinLogan Dynamo Foundation 12 (larger subwoofer, ranked higher, estimated 3.4/5), the MartinLogan Dynamo 10 (larger subwoofer, estimated 3.4/5) and the MartinLogan Dynamo 12 (larger subwoofer, rated 3.5/5).
Pros: MartinLogan’s entry subwoofer: a sealed cabinet with a 10” polypropylene woofer and a 400W peak (200W continuous) Magnitude amplifier, rated 25 to 200Hz (±3dB). It works with MartinLogan’s Sub Control app and Anthem Room Correction and has XLR and RCA inputs.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Dynamo 12 (110.6dB in the 40 to 80Hz CEA-2010 bands). A small sealed box with 200W continuous will play quieter than that.
