Speaker Width?

Another + for Jim Smith's book Get Better Sound.
My setup sounds best with my speakers 7 feet apart (tweeter to tweeter) and my head 11.5 feet from plane of tweeters.

Hey, here’s an idea. Why doesn’t someone compare Jim Smith’s speaker set-up method with the speaker set track on the XLO Test CD? 

What is the big deal about XLO Test CD?

Is it any similar to a combination of...

and one like this (with a different cover, but essentially the same, it does have polarity check, etc.)...

Now, imagine how I felt. I have not recovered yet.

Don't know if it's been mentioned in the thread but R. Vandersteen has a speaker placement method that works in my room.  Divide the width and length of the room by odd numbers and the intersection points are potential spots for placement.  

Then careful trial and error determines the best placement - and he mentions when you find it you will know and he is correct in my case.
