Inquiry (采购产品): home theater I am beginning to finish my basement. I plan a home theater in part (15 x 21 x8.5). I am seeking products for sound isolation but not fully deadening the room. The ceiling at this time is open to the joists. Two walls are finished with wallboard, the outside wall has polysteel behind it, the inside is part of a stairwell, the other two walls are to be constructed. Recommendations would be appreciated.
