Jamo SUB 800 - ranked #38 of 48 Small Home Subwoofers (Under 30 lbs) · Editor's rating 2.9/5

#38 Jamo SUB 800: $499 eBay

Pros: A tiny 4.6kg, 20cm-cube subwoofer that can add useful bass in a compact 2.1 or satellite system without dominating the room. Its passive-radiator design produces respectable measured output for its size: 103.2dB at 50Hz and 108.4dB at 63Hz. Reviewers found it capable of surprisingly low extension when carefully adjusted.

Cons: 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. Reviews also find its balance difficult to dial in, where restraining the low-end thud can leave a mid-bass hole. It suits a small room and modest satellites, not high-impact cinema bass.

How it compares: Just above it: JL Audio Dominion d108 - $601 more. Just below it: Gallo Acoustics TR-1 - $100 cheaper.
