Short answer: the JL Audio Dominion d108, if you are buying new, though neither ranks well in its class. The Jamo SUB 800 measures as well as it (#59 vs #58 of 73 subwoofers, 2.9/5 vs 2.9/5) but is discontinued, so only consider it used; the JL Audio Dominion d108 is still sold new at $1,000. Both are rated below 3.0/5 among the 73 subwoofers, and the Edifier T5s, ranked #2 at $169.99, is a better place to start if sound quality matters.
What the Jamo SUB 800 does well: A tiny cube subwoofer with a passive radiator that adds bass to a small 2.1 or satellite system without taking up floor space. The catch: Its small driver and cabinet run out of steam in the deepest bass: measured output falls to 84.1dB at 31.5Hz and 95.1dB at 40Hz.
Why pick the JL Audio Dominion d108: A compact sealed 8 inch subwoofer under 30 cm tall that adds upper bass support to a modest room. Watch for: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects.
Buy the JL Audio Dominion d108, since the Jamo SUB 800 is discontinued and only worth hunting down used.
