Need some advice from the experts here. I have a dedicated theater room, and recently converted to an AT screen. The space behind the AT screen is somewhat limited: 19" to the wall with a larger opening 45X60 (cutout from the fireplace above) right behind the center of the screen. Current sub (velodyne DD15) placement is on the right theater wall about 6' from the screen. I get good response from this location (verified by my pre-amps room correction software).
I would like to move my sub behind the AT screen. However, when I put in the the cutout behind the screen, I get bad response from as compared to it's original position. There is enough room for two subs in the cut-out. Will a second sub in the same general location help at all with response? If there is a good chance, I'd like to get a second sub so I can have the subwoofer(s) behind the AT screen and free up that front space in the theater. Any thoughts on if this will help??
