Aggielaw the following dimensions apply to the centre of the front of the speaker
23.5 inches from side wall and 37.25 inches from rear wall
The speakers are toe-in 0.5 inch.
I tried several toe-in angles, but for the Sonograms in this room the angle selected gave the widest image with the greatest depth and kept standing waves to a minimum.
I had read lots of posts on speaker placement and they all talk about the image snapping in place - my experience was a little more gradual.
I must admit that this new "spaciousness" only came about after getting all my "other ducks" in a row - in my case those last ducks were my interconnects, power supply and power cords, without which I do not think the whole thing would have come together so vividly.
Not that the old ones were bad, they just didn't have the same synergy as those currently in place
It freaks me out just how good this system sounds now :-)
