I remember once upon a time using a Sheffield Labs disc that had an in-phase/out-of-phase track and Doug or Rodger (I cannot remember which) said, when out of phase, to position the speakers enhance the out of focus as much as possible (when out of phase) and then when they were back in-phase, that positioning would result in very tight focus. So I did that, and that turned out to be what I consider a rather severe toe-in in a near field room, and the focus did wind up being real tight . . . but I lost a whole lot of peripheral sound stage. Now I don't use any toe-in at all . . . focus is good and I have (by my standards) pretty good peripheral sound stage.
Of course, this is all in a near field listening environment, and that is not what you have.
