Short answer: the ELAC Varro RS500. It ranks #143 of 212 subwoofers by sound quality, rated 3.6/5, at $1,399. The MartinLogan Dynamo 12 ranks #149, rated 3.5/5, at $1,279.99, $119.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the ELAC Varro RS500: Sealed reference enclosure with a 10-inch aluminum sandwich cone and HEX surround powered by a 500W RMS BASH amplifier. The tradeoff: Sealed alignment requires significant power down deep, resulting in lower maximum burst SPL than ported counterparts at 20Hz.
Why pick the MartinLogan Dynamo 12: Independent CEA-2010 testing records 91.7 dB at 20 Hz and 110.6 dB through 40-80 Hz. The catch: Nearly all controls, including low-pass frequency and phase, are app-only, with no physical switches for systems that lack separate bass management.
Buy the ELAC Varro RS500. It is rated higher for sound quality, and the $119.01 saving on the MartinLogan Dynamo 12 is not enough to make up the difference.
Worth knowing: the ELAC Varro RS500 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.4 to 3.8, so treat this verdict as provisional.

Cons: Nearly all controls, including low-pass frequency and phase, are app-only, with no physical switches for systems that lack separate bass management.
