Speaker distance

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.

Dynaudio Special 25, 8 feet center to center, room is 6 meter X 10 meters and 1.5 meter from the back wall with slight toe. Speakers need to breath.

I have room treatment and have spent hours with speaker placement.

Depending on the weather (literally) my soon to be new set up will allow the speakers to be anywhere from 6' apart (when the wall heater is not used) to 8 1/2' apart during the winter. I sit about 7'10" from the front plane of the speaker and will soon be able to increase it about 6"-8".

This is the one aspect I've always been unable to address due to room set up but with my next speaker and base, it will be much easier to move around and experiment.

All the best,
