Coverage note. Speaker Ranking currently covers 3 OSD models across subwoofers. These are the products in our database, not a complete list of everything OSD makes.
What this page covers. The OSD models ranked here span subwoofers, including OSD (Optimal Speaker Design) SS8, OSD (Optimal Speaker Design) TreVoce 12 DSP and OSD (Optimal Speaker Design) PS10. Use each model’s category position to compare it with alternatives of the same size and use case.
This page lists all 3 OSD speakers ranked on this site across subwoofers. Each model is shown in the category where it competes, with its current rank and the size of that ranking.
Use the category position rather than the brand name alone: speakers from the same manufacturer can perform very differently by size, price and product family.

Small Home Subwoofers (Under 30 lbs)
Ranked #15 of 48 in Small Home Subwoofers (Under 30 lbs) - OSD (Optimal Speaker Design) SS8: $249 Discontinued eBay
Pros: Independent CEA-2010 testing records 76.7 dB at 20 Hz and 111.0 dB through 40-80 Hz. The ported, side enclosure with 8” (203mm) 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 400.0H x 539.8W x 139.7D mm cabinet and 5.2 kg mass still need deliberate placement and calibration. Discontinued.
Notes: low profile (<8in)
