Speaker Positioning

Exact measurements become irrelevant when you don't have a bilaterally symetrical room. My system is in a 'sunken' living room. Right side has a large window behind the speaker, and a very large picture window to the right along the wall. Left speaker has an opening, some day a window, otherwise a long drywall surface. So not equivalent. The room opens to a dining room, staircase, etc., so no reflections to deal with. But speaker placement has to be done using the ears, not a tape measure, at least in this case. 
I found much better sound as I inched both speakers away from both the back wall and the sides... Just trust your ears!

It's easiest with Klipschorns.

What? Since when? Exact measurements become irrelevant when you are deaf in one ear. As long as you have two working ears its the distance between them and the speakers that determines imaging. That's why we have two ears. Two eyes, depth perception. Two ears, localization. If you can't localize the predator then guess what? Hey, you! Out of the gene pool!

Yuk-O Gene pool! No swimming for me... :-)

BUT

Only one mouth... Yet what gets used the most?

Don’t seem proportionate. Does it?

Rooms suck!!! Plane and simple.

Well there you have it.. you ever wonder why a prairie dog has a "mound", and conductor is in a "Pit"?

One wants to see and not be heard, the other wants to hear but not be seen. A simple turn of the head, in either case, gives the results they want...Are you in a PIT, or on a MOUND? Do you want to see or hear?

Just a question? Yea placement is everything... Not an average, as you infer...

Think on that one for a while... good, Better. BEST... ay..

If you follow the Cardas formula, you may wind up with speakers way out near the middle of the room. Maybe not too practical if it isn't a dedicated listening room.

Another method seems to work well for me.  I've seen it called the "Allison Rule":
"The Allison rule basically states that the distances from the woofer to the floor, woofer to the side wall, and woofer to the back wall should be as different as possible. To accomplish this, one would apply the following equation: Middle distance squared = shortest distance multiplied by longest distance."
(Don't know where I found this, maybe in an Audiogon discussion)

Once the speaker positioning is done, place the listening chair to form an equilateral triangle. Tweak to taste.

This method is flexible because it allows you to swap which ones are the short and the long distances.  For the woofer to side wall measurement, you might try starting with the Rule of Thirds. But even if you move the speakers farther apart than the RoT dictates, you still can apply the Allison Rule.
