MartinLogan Dynamo 12 vs JL Audio Fathom f110

Short answer: the MartinLogan Dynamo 12. It ranks #105 of 145 subwoofers by sound quality, rated 3.5/5, at $1,599.99; the JL Audio Fathom f110 ranks #139, rated 3.0/5, and costs $2,299, which makes this an easy call rather than a real tradeoff.

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.

The case for the JL Audio Fathom f110: Compact sealed 10-inch punches well above weight class with fast detailed musical bass.

Buy the MartinLogan Dynamo 12. It is rated higher for sound quality than the JL Audio Fathom f110 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
