Short answer: the MartinLogan Dynamo 10. It ranks #175 of 212 subwoofers by sound quality, rated 3.4/5, at $899; the Aperion Audio Bravus II 10D ranks #209, rated 2.9/5, at $899. Close enough in price that the sound-quality gap is the deciding factor.
The MartinLogan Dynamo 10 is the better-sounding choice. Down-firing ported subwoofer featuring a 10-inch high-output driver and 200W RMS / 400W peak Magnitude 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 MartinLogan Dynamo 12 (110.6dB in the 40 to 80Hz CEA-2010 bands), which has a larger woofer, so it is placed just below it.
The case for the Aperion Audio Bravus II 10D: Compact 15 inch tall cabinet pairs a down-firing 10 inch aluminum cone woofer with two side-firing 10 inch passive radiators. The tradeoff: No independent measurements yet, so its output can’t be compared with ranked subwoofers; the rating is estimated from the measured original Aperion Audio Bravus 10D, which averaged only 102.5dB in the 40 to 80Hz CEA-2010 bands and 79dB at 20Hz.
Buy the MartinLogan Dynamo 10. It is rated higher for sound quality than the Aperion Audio Bravus II 10D at the same price, so only choose the other one for a particular feature it does better.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: MartinLogan Dynamo 10 3.1 to 3.6; Aperion Audio Bravus II 10D 2.6 to 3.2). Treat this verdict as provisional.

MartinLogan Dynamo 10: $899.00 Estimated Amazon eBay
Older model: the MartinLogan Dynamo 800X (ranked higher, estimated 3.7/5). See every MartinLogan Dynamo generation.
Same family: the MartinLogan Dynamo Foundation 10 (smaller subwoofer, estimated 3.1/5), the MartinLogan Dynamo Foundation 12 (smaller subwoofer, estimated 3.4/5) and the MartinLogan Dynamo 12 (larger subwoofer, ranked higher, rated 3.5/5).
Pros: Down-firing ported subwoofer featuring a 10-inch high-output driver and 200W RMS / 400W peak Magnitude Class D amplifier. Down-firing port enhances room coupling and deep bass output for media rooms.
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), which has a larger woofer, so it is placed just below it. Enclosure and amplification yield modest clean output below 27Hz.

Aperion Audio Bravus II 10D: $899.00 Estimated Amazon Aperion Audio eBay
Older model: the Aperion Audio Bravus 10D (ranked higher, rated 2.9/5). See every Aperion Audio Bravus generation.
Same family: the Aperion Audio Bravus II 8D (smaller subwoofer, estimated 2.6/5) and the Aperion Audio Bravus II 12D (larger subwoofer, ranked higher, rated 3.7/5).
Pros: Compact 15 inch tall cabinet pairs a down-firing 10 inch aluminum cone woofer with two side-firing 10 inch passive radiators. A 500W RMS Class D amplifier (1,000W peak) drives it, and Aperion rates it at 28Hz at the -3dB point. Aperion sells it direct with a 30 day in-home trial and free shipping in the continental US.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers; the rating is estimated from the measured original Aperion Audio Bravus 10D, which averaged only 102.5dB in the 40 to 80Hz CEA-2010 bands and 79dB at 20Hz. Its 2 year amplifier warranty is short next to the 5 years on cabinet and drivers.
