#5 PSB Speakers SubSeries 450: $1,898.91 Discontinued eBay
Same family: the PSB Speakers SubSeries 100 (smaller subwoofer, rated 2.6/5), the PSB Speakers SubSeries 200 (smaller subwoofer, ranked lower, rated 3.8/5) and the PSB Speakers SubSeries 250 (smaller subwoofer, ranked lower, rated 3.7/5).
Pros: A 12 inch passive radiator subwoofer with tight, precise bass that suits music as well as movies, now discontinued. It has a 12-inch driver and passive radiator with a 400W RMS (1000W peak) amplifier, rated 20 to 150Hz at plus or minus 3dB. Measured output averages 122.1dB from 40 to 80Hz and reaches 124.9dB at 80Hz, very high for a 19.5 kg cabinet. It has 114.1dB at 31.5Hz and 107.1dB at 25Hz, and the sealed passive-radiator design avoids port noise.
Cons: Output falls to 94.1dB at 20Hz, so the lowest movie effects get far less output than the midbass. The cabinet is 384.0H x 390.4W x 422.1D mm and weighs 19.5 kg. It is expensive for a single 12-inch subwoofer, and it is discontinued, so it has to be bought used.
