I am setting up a home theater system in a media room. The size of the room is 17' wide x 20' deep. It's going pretty well but I was wanting to put the sub out of sight. There is an 18" high 24" deep stage that is below the screen. It will be carpeted on top with wood paneling on front. The stage is stickly for looks. I was wondering about putting the sub under the stage and then leaving a hole in the front (with material over it of course) for the sound to come through. Is this a good idea or bad idea. Please advise!!
