Speaker distance

Golden Ear Trition Reference (pair) set apart 7 feet (essentially form an equilateral triangle to the PLP).

The XLO Test CD Speaker Placement track is a fool-proof method for determining OPTIMUM locations for ANY room and for ANY degree of room treatment, including no room treatment, for a constant listener position.

Can you describe (in writing here in this thread) how this track "works" in order that it is "fool-proof"?

Thanks.

@geoffkait 

Thank you.

What are the disadvantages of having to little or to much space
between your speakers?

It will not sound as "correct" as it otherwise *could*.

And that can ONLY be done with a careful long term program of room treatment plus the fabled XLO Test CD speaker placement track IMHO.

Hello Geoff. To your point about the XLO test cd, which I then had a follow up with you where you stated (paraphrasing) it's the "in phase followed by out of phase" track which is used (diffusion), I'm of the opinion that any purpose built cd with these types of tracks could be used effectively, correct?

For instance, in my case I use/have this one https://www.cduniverse.com/search/xx/music/pid/1526639/a/denon+audio+technical+cd.htm&frm=www.cd...

Track 2 has in/out phase.

Your opinion is appreciated. Thanks.

The Denon CD does not explain (verbally or documentation) how to use the out of phase track. So your point is well taken.
