Continually adding on

I love the home theater system that my husband just recently bought. We watched Star Wars the other night and the neighbors called again to find out what all the noise was and if they could come over and watch it also. We recently purchased a set of home theater sconces that compliment our system nicely. Were getting to the point where my husband is actually considering adding on to the house to create our own theater room with recessed floor and high ceilings for acoustics. I suggested that we buy an actual theater popcorn machine for added effect but he felt that this was a bit much.
