The speakers are precisely 45.5 inches from the back wall.Larryi, I don't think his speakers are too far apart.
They are each 26.5 inches from the side walls with a caveat. The left speaker is 27.5 inches from the window sash, which is 1 inch deeper than the wall. It's 30 inches to the top panes of glass and 28 inches from the lower panes of glass. But measured from the actual wall, both speakers are exactly 26.5 inches from the wall.
The speakers are precisely 90.5 inches apart.
The listening position is pretty close to 45.5 inches from the back of the room.
Looking at the photo of his room it looks like he has the speakers setup along the long dimension i.e. along the 189" dimension.
if the speakers are 45.5" from the wall & the listening position is 45.5" from the other wall, then, he should be 98" from the speaker which is little over 8 feet. The speakers are 90.5" apart which is 7.5 feet. I don't think that his speakers are too wide vs. his seating distance.....
maybe you mis-read one or more of the dimensions in his orig post??
