Brand: MartinLogan

#25 MartinLogan Dynamo 700w: $999 Discontinued eBay

Pros: A discontinued compact sealed 10 inch subwoofer that adds upper bass weight to movies and music. Independent CEA-2010 testing records 86.3 dB at 20 Hz and 109.0 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with 10” (254mm) driver delivers substantial upper-bass output for movie effects and music.

Cons: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 318.5H x 296.9W x 318.3D mm cabinet and 12.0 kg mass still require deliberate placement and calibration. Discontinued.
