I have Aperion bookshelf speakers. I moved to a new house and now my entertainment room has to be re-configured. My wife does not like looking at speaker, anywhere. So I am trying to make everything as stealthy as possible. I would like to know if I can turn these speakers into in-wall speakers. I have a wall that is about 2.5 feet thick the wall is hollow and lined with drywall. So I can cut out a hole in the wall and build a shelf in the hole to store the speaker. The hole/opening in the wall will be about 50% bigger than the speaker and there will be nothing but air behind the speaker. I can cover the opening where the speaker will sit, with speaker cloth, to hide the speaker. This will give the speakers a "built in" look. Any opinions? Will this work?
