Another obsession of mine. Heres the theater room I built in the basement of my house. It was once a gym, until I added on, and then it was a playroom for the kids, until they turned it into a mess. So I took it back and spent some time researching equipment and the proper way to setup a theater. (ie: a few other forums I frequent.
Equipment stack built in the wall
Center speaker stand and 2 channel equipment
I also have a vintage Carver system in my office
And another small surround system in the bedroom along with the 2 channel system that is connected throughout the house. Oh, and I have an old Yamaha reciever in my garage for backround music.
Like I said, another obsession!
