Speaker distance

At the moment Gallo CL-3  6'6' apart, 37 " out from a VERY thick outside wall .I sit 6' away . Near in Condo .

Owned at least 50 prs of speakers in last 50 years,  only one I really miss
are  DCM Time Windows .

Golden Ear Triton Reference.  8 feet apart, center to center.

9 feet 5 inches center to center, Thiel CS6

This is an interesting thread!

I have Acoustic Zen Adagios, 9'3" apart and 11' 3" from my ears. This is based on Jim Smith's ratio of the distance between speakers being .83% of the distance between your ears and the speakers.

However, I've been reading various Verity Audio manuals for their line of speakers, and they have some interesting measurements I'd like to try. For example:

If you're sitting position is within 10' of your speakers, you should have an equilateral triangle (60 degree angle between you and your two speakers).

If you're sitting more than 10' away, "the width of your room divided by 3.6 will give you the distance from the side wall to the center of the front baffle of your speakers."

and, "the distance from the rear wall to the speaker front baffle of your speaker (midrange center) should be equaled to the height of your room times 0.62."

I hven't tried these latter measurements - as they're calibrated towards Verity Audio speakers - but even an inch difference in your speaker location can significantly change the sound. 

I’ve said it before and I’ll say it again — almost all speakers are too far apart. The speaker placement track on the XLO Test CD points out that, all things being equal, one should start out about 4 feet apart and slowly work outward. You don’t want to miss the sweet spot. 😛 Folks often instinctively think wider apart means wider soundstage but that’s an Old Wive’s Tale. 😃 Ditto toe in. It all depends, it depends a lot on room treatments, for one.
