I'm converting my living room into a dedicated home theater. The room is 18' x 13.5' and is directly above an unfinished basement, and has a wood floor which is the ceiling for the basement. I plan on carpeting the floor and doing the usual acoustic treatments, but I was wondering about the subs. Should I build something like ASC's subtraps, to decouple them from the floor and also to help with the vertical room mode?
