Short answer: the MartinLogan Dynamo 12. It ranks #131 of 185 subwoofers by sound quality, rated 3.5/5, at $1,599.99. The MartinLogan Dynamo 10 ranks #166, rated 3.3/5, at $899.99, $700 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the MartinLogan Dynamo 12: Independent CEA-2010 testing records 91.7 dB at 20 Hz and 110.6 dB through 40-80 Hz. The tradeoff: Nearly all controls, including low-pass frequency and phase, are app-only, with no physical switches for systems that lack separate bass management.
What the MartinLogan Dynamo 10 does well: Down-firing ported subwoofer featuring a 10-inch high-output driver and 200W RMS / 400W peak Magnitude Class D amplifier. The catch: Enclosure and amplification yield modest clean output below 27Hz.
Buy the MartinLogan Dynamo 12. It is rated higher for sound quality, and saving $700 with the MartinLogan Dynamo 10 does not make up for the sound-quality gap.
