I need some clarification, you say 3700 sq ft, did you mean cubic feet? We have a pretty nice sized ranch, and my basement is 2200 Sq Ft, but the HT/Rec Room is 900 Sq Ft. The HT portion of this larger room is over in one of the corners which is about 15ft x 25ft or so. The EP500 blows me away and I swear my house is coming off of its foundation sometimes.
