Speaker separation versus listening distance??


Is there a formula for separation distance between speakers, versus sitting/listening distance?

The Wilson WASP method says between 1:1.1 and 1:1.25 listener distance to speaker distance. Link
sorry, meant speaker distance to listening distance. IOW, listening distance is a little further away
NHT recommended 1 to 1.5, meaning if your speakers are 6' apart you want to be 9' away.

What are your speakers? Some speakers have different requirements than others.
Vandersteens don't like side walls.
Maggies don't mind side walls.
Tall speakers like Dunlavys need a little more distance from the listener to integrate the drivers.
