Brand: PSB

#71 PSB Speakers SubSeries 100: $299 Discontinued eBay

Same family: the PSB Speakers SubSeries 200 (larger subwoofer, rated 3.8/5), the PSB Speakers SubSeries 250 (larger subwoofer, rated 3.7/5) and the PSB Speakers SubSeries 450 (larger subwoofer, rated 4.2/5).

Pros: A tiny, light sealed subwoofer that tucks almost anywhere to add some bass to a small desk or bedroom system. Independent CEA-2010 testing records 78.1 dB at 20 Hz and 99.2 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with 5.25” (133mm) driver is best suited to upper-bass support in a modest room.

Cons: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects. The 161.8H x 161.8W x 199.9D mm cabinet and 2.7 kg mass still need deliberate placement and calibration. Discontinued.
