1) Perhaps a good term for this type of installation is “subbasementwoofer.”

2) Unlikely to find one just like it on Ebay. Then there'd be the shipping charges!

3) In one of the pics you can link to, notice there is only one chair going in that room. But at the bottom of this page , you can see they have put in a couch. If I spent what they're spending, I'd share.
