Mine were roughly 8 foot off wall at the "sweet spot" but I also had my MLP further back into the room so I'm not sure the distance of the speaker to the MLP but since I've only moved it between a foot or two it should be easy to replicate. All I need to put on is Glenn Miller's "In the mood" and see if I am sitting amongst the orchestra again.
