When I sit down to watch movies on my home theater, I'm backed up against a wall, literally. Now, sitting on my bed next to a wall while watching my movies makes my sub kinda "ring" my ears and sound heavier than normal. Is there anything I can do about this? My home theater is nicely placed, despite me sitting on my bed. My bed is at a nice couch like heigth with my rears mounted to the walls on each side of me and my bed is in the direct center of my TV, center channel and two fronts. Anyway, what can I do?
