#43 Definitive Technology SuperCube 8000: $1,299 Discontinued eBay
Same family: the Definitive Technology SuperCube 2000 (smaller subwoofer, rated 3.7/5).
Pros: A small footprint subwoofer that fills large rooms with loud, extended bass from a heavily braced cabinet, now discontinued. It has an 11-inch driver with a passive radiator and 1500W peak of amplification, and measured output averages 117.7dB across the 40 to 63Hz bands. It still reaches 102.0dB at 20Hz and is rated down to 12Hz. The cabinet walls are nearly 2 inches thick with internal bracing, in a footprint of about 1.8 square feet.
Cons: It weighs 30.4 kg in a 413 x 387 x 406 mm cabinet, which is heavy for its size. It is discontinued, so it can only be bought used. The CEA-2010 average covers only 3 of 4 bands, so output in the very lowest band is unconfirmed, and output drops from 108.6dB at 31.5Hz to 102.0dB at 20Hz.
