GoldenEar ForceField 3: $650 Discontinued eBay

GoldenEar ForceField 3 ranking card

Pros: Independent CEA-2010 testing records 110.2 dB (avg of 3/4 bands) through 40-80 Hz. The passive radiator enclosure with 8” (203mm) driver is a compact way to add useful midbass support to a modest system.

Cons: Without a published 20 Hz result, deep-bass capability is less certain than the midbass figure. The 292.1H x 288.8W x 400.0D mm cabinet and 11.8 kg mass still need careful placement and calibration. Discontinued.

MartinLogan Dynamo 700w: $999 eBay

MartinLogan Dynamo 700w ranking card

Pros: 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.
