I need some help here. I am in the process of building my HT and I'm at the point where I need some help. I am building my HT in the basement on a concrete floor and have a stage 3'6" x 12' and a raised seating area 10' x 12'. I need to insullate between the joists because the bass reverberates like crazy. I've see some people use sand as a sound deadener but was wondering if there is anything cheaper or less work to install. I apprecaite your comments.
PS: To get a better idea of what my project looks like check out my gallery.
