So, it is really true. Formula are simply a starting point. For me, I did my movements over a year. I plunked them in the prescribed place. And listened for a couple months (they are really awesome speakers). I realized they were capable of disappearing, but were not and the soundstage was restricted. So, I toed them out some. Listened for a couple weeks. No question… better. Moved again. Better. Some folks move, listen, move, listen… in a day. I find that confusing. I prefer listening to the music and wholisticly appraising the change.
Thank you, @ghdprentice , I am keeping this in mind as I work on this. You are more patient than I am. I am often lazy, but less often patient. I am using the formula that bigtwin provided as a place to start from this time around. In the past it was always how far do I think I can get away (get away from a sonic perspective, not the perspective as 'am I allowed to') pull them out & spread them a part. This is about as scientific as I have ever got with this aspect of the hobby.
