For the true theater experience, you're going to want to crank up that surround sound. But what you don't want is your neighbors or sleeping children to experience it with you, so you may want to think about soundproofing your media room. They're not cheap, but soundproofed walls will accomplish two things: insulate the booming sound so you don't disturb the rest of the house and improve the sound in the room itself. Don't worry, we're not talking about those ugly gray foam acoustic tiles plastered all over your walls. You'll have many design-centric options to choose from, like fabric panels and even soundproof wallpaper.
