Short answer: the Polk Audio PSW10. It ranks #17 of 48 subwoofers by sound quality at $209; the MartinLogan Dynamo 700w ranks #19 and costs $999, which makes this an easy call rather than a real tradeoff.

Polk Audio PSW10 vs MartinLogan Dynamo 700w

What the Polk Audio PSW10 offers: 10-inch Dynamic Balance polymer composite driver with 100W Peak Class D amp. Deep bass capabilities are impressive with exceptional definition/control per CNet. Reduces distortion (uncommon at this price). Good hard clean bass performs well at higher volumes. Easy setup and affordable price consistently highlighted by thousands of buyers. Polk Power Port channels airflow cleanly for tighter bass without port noise. Best for average/small rooms and apartments. Watch for: Budget-tier construction, ported room dependency, lower 110.3 dB output, and $250 entry-level positioning.

What the MartinLogan Dynamo 700w offers: 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. Watch for: 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.

Buy the Polk Audio PSW10. It ranks higher for sound quality than the MartinLogan Dynamo 700w and costs less, so there is no real case for the other one.
