I'm looking at installing a HT in the basement of my house. I wonder if any one has even installed a sub into the floor joist overhead? I currently have a drop ceiling and I'm not worried about sound isolation, obiviouly. The area for HT is about 20'x10'8"X7'high. I just figured I could hide a sub or 2 away and save on the enclosure, where is the best place for a thing like this? Anyone? Thanks.
