Well the theater is functional. We watched the 3rd twilight movie last night. It's pretty awesome and I haven't even finished the room treatments.
Here is the Screen just after we installed the spandex.
Here is the spandex that was used, the front layer was White moleskin matte spandex, and the back layer was light grey milliskin matte.
Here is the custom bracket for hanging the screen. I had to offset it so that I could get the pivot point over the height of the screen tight track that was used to mount the spandex.
The mounts just hang on 5/16 lag screws.
Here is the first picture of the screen hung. It is 151" wide or 164" diagonal. I Figure bigger is always better, and I can always mask it down.
Here is the front of the theater.
Here is a shot of the back.
Here is the front of the rack.
Here is the back of the rack.
And finally a shot of the projector mounted.
My screen size has grown since the beginning of this project and because of that the recess in the ceiling for the projector mount isn't quite far enough back for the projector to completely fill the screen. Right now I am only projecting about a 145" wide image in scope. Even so I think it looks great. One thing that has surprised me is how good the sound seems to be. The room doesn't have enough absorption yet and you can hear an echo when you yell but while watching a movie it sounds great.
