How far should you be sitting from your speakers?

I have a pair of Martin Logan Summit speakers. I wanted to know everyones thoughts on how far away should I should be sitting from Electrostat's.
I have the Summits 8' apart and I am sitting 10' away at this time. I tried sitting in a perfect triangle 8' but it seemed to close to sharp in the highs.
What is the ideal position?
What sounds best to you.
Cardas cable has a mathmatical formula to identify exact speaker placement. I've experienced awesome success using this method. Go to their website and check it out! Good luck.

"If you think you can you can".
All of the theories are a starting point. There is no formula that takes into consideration all the nuances of your room, your system, and your ears.

Find a good starting point and then go by ear.

If you think you can do anything because you believe, you are a lunatic...

A good rule of thumb is a seating distance equal to the distance between the speakers, from tweeter to tweeter (measured center to center).

If you experienced hot tweeters, you might try adjusting the toe-in so the tweeters are not pointed at the listening position.

Putting some acoustic treatment (absorbtion or diffusion) at the point of first reflection on the side walls will help.

Also, you can try scotch taping one sheet of toilet tissue over each tweeter. Don't laugh. It works.

Otherwise, you might just have hot tweeters...
'hot tweeters?' I feel dirty.
Another way that will work, Use a steady 1K pink noise tone adjust spacing and distance for a Ball of sound Perfectly between the speakers. The ball of sound will be very noticable when obtained. This can take a while.
You've got the speakers beaming at your ears. Experiment with cutting down the angle ever so sligtly a little at a time until you get out of the hot spot.

Exactly. In other words, adjust toe-in.
IK pink noise tone? Not sure what the poster had in mid. IIRC pink noise has equal SPL per octave averaged over time vs white noise that has equal SPL throughout the bandwidth. The effect of pinking noise is to reduce the level per Hz at higher, broader, octaves, demphasizing high frequencies. Like white noise, pink noise can be band limited. By its very nature, the instaneous level of either noise source is variable. The balistic response of a sound level meter is often set to slow, so it integrates the flutuations to obtain a more useable reading. Perhaps the poster had in mind narrowly filtered pink noise, but the tighter the band limit the more variable the level balistics.

Pure simple test tone 1K pink noise. available from many test cds ect. When properly spaced ect there will be air around and behind the "ball of sound" Be sure to use a movable chair to find the correct lock in point. This will bring imaging up to parr and will do nothing for optimum bass responce so you results will be used as a starting point.
One could use a mirror to find the refelction points on side walls ect to place sound absorbing material at that point to help with reflections.
