Hello! I have a room that I am dedicating for a home theatre. The only thing in this room will be a couch and the home theatre. The home theatre I am looking at is a 27 inch tv, h/k 520 reciever, 4 jbl s38's for front and rear, s center, and a 25-31 pci sub. Will this setup sound good in a 15x12 foot room? Will this be to much for this room, or will it sound awesome? The room is fully enclosed which is why I chose it to get good acoustics. So will this work well or not?
