I was wondering if anyone could give me some suggestions. I just got a new denon 1712 which is an upgrade from the 6.1 receiver I had. My question is this, I received a matching in-ceiling speaker to the ones I have now and need advice on possible placement.My current setup has the three surrounds sitting over my couch and was wondering about the placement of the 4th one. I was wondering if I place the 4th the same distance apart to the right of the speaker on the right if that would be too far to the right. You cant tell from the pic but they are equal distance apart. My current setup has the right speaker over the right edge of the couch.I can only go to the right as the wall is only a few feet from the left speaker. Any advice would be appreciated.
