Which begs the question.  How does one mount TB2s in the back for surrounds?  I guess you could use the higher 'Pro' stands, but, is there a way to wall/ceiling mount them.  For ceiling a center channel orientation would probably work better.  About to start getting into a Condo, so wondering what I should go for.  
Also, where can we get the wall mounts (already have a pair of DB1Ss), from our local dealer, or direct from the distributer?
