I'm just starting to research what equipment I will need to set up a home theater in my basement. I finished my basement several years ago and had set aside one area for Home Theater (its already prewired). The area I intend to use for HT is about 12 ft wide by about 21 ft long with a drop ceiling that's 8 ft high. I'm interested in going Front Projection for the size/price advantage. Given the dimensions I'm dealing with, what size screen can I expect to accommodate within this space? Any info would be appreciated.
