The cost of some studs and drywall is pretty cheap. Mud/tape the joints, and even if they are ugly as heck, they will help with the sound, and it is clear that you don't care if it is nice looking since there will be a false wall, you never have to do anything more with it. Obviously, the more mass (double drywall) the better, but anything will be better than nothing.
Personally, I finished the whole room including texture, paint, and even fancy outlet covers including the area that is behind the false wall.
Nobody will see that I spent about $50 on the outlets, jacks, and designer plates, or that the wall is finished just like the rest of the room since it is accoustically treated and the corners have bass traps, but if I ever do something different with the room, or go to sell the house and the people don't want a theater room, all I have to do is take everything down, patch some small holes in the drywall, texture, and repaint. I could have it looking like a regular room in just a few hours of work (with a couple of days for things to dry between steps).
Again, just buy $30-$35 worth of studs and drywall and you will be much better off. Throw in another $10 or so for a little mud/tape, and you will be better off.
