CES 2011

The Principal Grand subwoofer from Vienna Acoustics packs a 12-inch pulp-carbon driver into an enclosure with two separate chambers for the 300-watt amp and crossover. The latter, as shown in the pic, is on the bottom. The company, which actually manufactures in Vienna, is fussy about its drivers, in this case source from ScanSpeak because it's important for a sub "to play more than one note." Amen. Pricing ranges from $3000-4000 depending on finish. Also shown was the Strauss Series In-Waltz in-wall speaker, with features derived from an on-wall cousin.
