#140 OSD (Optimal Speaker Design) PS10: $399 Discontinued eBay
Pros: An affordable 10 inch sealed subwoofer in a compact cabinet, now discontinued. Measured output averages 112.0dB from 40 to 80Hz and peaks at 116.1dB at 80Hz, strong for a 125W RMS sealed sub. The cabinet is about 343 x 362 x 343 mm and weighs 15.0 kg, so it fits easily in a small room. Its rated response runs from 25 to 180Hz.
Cons: Sealed output rolls off below 50Hz, dropping to 93.3dB at 25Hz and 85.0dB at 20Hz, so it will not deliver the lowest movie effects. The 125W RMS amplifier limits output in large rooms. It is discontinued, so it has to be bought used.
