While I think the Cardas method is interesting, there's no way I could do this in my particular room. With a width of about 16 feet (interesting, my room is near the "Golden Room" characteristics) for my room, my speakers would have to be about 7 feet from the wall. That's a huge distance (and would put one of the speakers basically in front of the door into the room). I may give this a try just to see what it sounds like, but I think I'll have to keep my speakers closer to the back (behind the speakers) wall.
