I don't remember the manual, but otherwise remember that like any dipole speaker, you don't want them too close to the wall?
As I think about it, I recall that there were primitive line drawings, which suggested fairly severe toe in?
I had a pair of Apogee Stage speakers for about 7 years and really liked them - excellent midrange.
I put them as far as possible out from the rear and side walls, with no toe in.
