I will be able to control the light in the room since it will be a dedicated HT room. However putting the speakers behind the screen would mean that the screen has to be about 2 feet from the wall. I don't think I would like this look and it would bring the screen closer to the projector and limit the screen size I could use. My distance from projector to back wall will be only about 11.5 to 12 feet as it is.
