My couch is actually 3 feet away from that back wall. Now, that back wall is a bedroom. I have considered taking it down and make my room 10 feet longer. However I'm not sure if that actually will gain a whole lot. Yest the affects coming from the rear will sneak up on you a bit and sound a little better. But then I might be too far away from the tv. And the room across will remain at 12'. And if I took that wall down I now have a 1700 squ ft 1 bedroom 2 bath home. When I sell, and that will be sooner than later, I hate paying these crooks in Illinois, I will have to put the wall back up. Not a huge deal, but something I have to seriously think about.
