Jeff Fritz sits on the "ultimate audiophile seat" from ReVox. Yes, you're actually supposed to sit on it -- it has a cushion and all, and it's clad in leather (matches the speakers) -- but if you look underneath, it's actually...

...an audiophile-grade subwoofer called the L Active Bass, which retails for (2400 €). After Jeff got up, Markus Halbig, general manager of ReVox Germany, was kind enough to do all the work for us and lift the seat/sub so we could shoot the underside.
