ARISE O SLUMBERING THREAD! I'll re-asking from my pre-wire thread, hoping for a quick response. http://www.hometheaterforum.com/t/321184/pre-wire-for-projector/30#post_3944719 Is it worth doing Sound channel in basement finished ceiling space for $655? The walls will be normal. This drops ceiling about 2", and gives some acoustic separation between basement and first floor. I've never experienced it, but I've heard about it. It seems like a good idea between the two main TV / movie / video game rooms. But if it's ineffectual with ceiling only, I don't want to waste money.
