Probably been asked before but I could not find with a search. I am in the process of building a very modest theater room (or more to the point, a theater end of a larger room) in my basement. Specifics: Room is open-backed but I will have walls on both sides to about 15.5" in length. Width is sllightly more than 11". Height is 7.5" to the bottom of the overhead joists, another 10" or so to the subflooring. LCD FP (probably a Sanyo Z2) on a ~100" screen. Marantz SR-7200 Paradigm Mini-Monitors plus Monitor series CC (forgot model number) Hsu VTF-2 sub The ceiling is painted white, which I will probably remedy somehow at a later date. Floor will be standard carpet in a dark color. I will hang 1/4" pile felt on the walls and will probably create a curtain for behind to help with ambient light. I am not an audiophile and this will really be a fairly modest HT as far as these things go. However, I am very willing to add some elements to the room so long as they are not too time-intensive to create and/or too expensive if the benefit is there. I guess I'm not entirely sure what the soundstage is for and if it is worth me adding one.
