OK, I have been convinced that an IB is the way to go. It will be my first project. Eventually, I want to get a front projector which leads to my question. If I have an Infinite Baffel sub in the ceiling, will it cause a ceiling mounted projector mount to shake? I have the option of putting it in a wall behind the listening position, but everywhere I read it says that is a bad idea. My room is 17 feet long, so I really don't have any other options other than a ceiling mount. I haven't done that much research yet on the front projector because that is about 1 or 2 years away from happening.
