Short answer: the MartinLogan Dynamo Foundation 10. It ranks #53 of 73 subwoofers by sound quality, rated 3.1/5, at $479.99. The Definitive Technology Descend DN8 ranks #56, rated 3.0/5, at $449.99, $30 cheaper, not enough of a saving to outweigh the sound-quality gap.
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). The catch: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured MartinLogan Dynamo 12 (110.6dB in the 40 to 80Hz CEA-2010 bands).
The case for the Definitive Technology Descend DN8: The smallest Descend subwoofer: an 8” active driver loaded by two 8” passive radiators (Definitive’s 3XR layout) in a cabinet about 33cm on each side, with a 500W Class D amplifier. The catch: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Definitive Technology DN10 (110.4dB in the 40 to 80Hz CEA-2010 bands) and Definitive Technology Descend DN15.
Buy the MartinLogan Dynamo Foundation 10. It is rated higher for sound quality, and the $30 saving on the Definitive Technology Descend DN8 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 10 2.7 to 3.4; Definitive Technology Descend DN8 2.6 to 3.3). Treat this verdict as provisional.

MartinLogan Dynamo Foundation 10: $479.99 Estimated Amazon eBay
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). See every MartinLogan Dynamo generation.
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 MartinLogan Dynamo 12 (110.6dB in the 40 to 80Hz CEA-2010 bands). A small sealed box with 200W continuous will play quieter than that.

Definitive Technology Descend DN8: $449.99 Estimated Amazon eBay
Same family: the Definitive Technology DN10 (larger subwoofer, rated 3.4/5), the Definitive Technology Descend DN12 (larger subwoofer, estimated 3.6/5) and the Definitive Technology Descend DN15 (larger subwoofer, rated 3.7/5).
Pros: The smallest Descend subwoofer: an 8” active driver loaded by two 8” passive radiators (Definitive’s 3XR layout) in a cabinet about 33cm on each side, with a 500W Class D amplifier. It reaches 35Hz, fits beside a TV stand or under a desk, and has level, low pass and phase controls.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Definitive Technology DN10 (110.4dB in the 40 to 80Hz CEA-2010 bands) and Definitive Technology Descend DN15. With a single 8” driver it will play noticeably quieter than either, and Definitive rates it only to 35Hz.
