I own a pair of FX500i's that I am using as left and right surrounds in a 5.1 system, I have them on top of bookshelves 5' tall which are located slightly behind and to the side of the sweet spot. the right surround is in a corner and the left surround is open to the kitchen so I had to go with bookshelves as stands seeing that I did not have a left side wall to mount on. My original intent was to mount them on the rear wall but my spouse did not want that look. A side wall is supposed to be better anyway so the bookshelf stands work pretty well. The issue I have is this: My wife does not like seeing the back of the left surround which is exposed in the kitchen so I found some large rubber stick on feet for the back of the speaker so I can lay them down and still leave space for the wiring, the result is that the speakers now point more toward the ceiling, they look great in this position but I was wondering if this would impact the sound and if I should still use the dipole setting?
