Building a wall in my basement to close off a room for a HT and the contractor asked what kind of insulation I wanted. He told me about a sponge type insulation which was a bit more money, but might be worth it as far as getting better sound. What do you all think? Would one type of insulation be better than another in trying to achieve the best possible sound? The rest of the wall is going to be wood studs and drywall if that matters.
