Actually I was talking about the back left corner of the left speaker and the back right corner of the right speaker. Those corners look like they are almost touching the wall. I expect my left speaker to be almost touching the wall just like how that looks. My right speaker will be the same like the left speaker with the back left corner almost touch my stair wall running parallel to the wall of the left side. That would give the back of my right speaker more breathing room behind than the left.
Of course a picture speaks volumes (pun intended)
