I am moving into a house with a garage that is pretty much useless, so I had the great idea of turning it into a dedicated home theater room. I don't have the best equipment at this time but I plan to start building. I figured the best way to start would be to have a room for the sole purpose of making the veiwing and listening experience the best that it can. Now, my question to you is, is there a difference in the insulation and drywall that I use in an acoustical sense? Should I put up wallpaper or paint? Carpet or cement? Should I suspend my speakers from the ceiling or put them on stands? I am very new to this but want to learn so any suggestions will help, thanks!
