what is the rule of thirds?


When reading posts about speaker placement I have often come across the "rule of thirds" with regard to where the speakers sound best in a room.Can someone explain?

Divide your room into thirds creating a grid. Then place you speakers on the 1/3d line (from the wall behind it). Bring your listening spot (your ears) out to the 1/3d line from the rear wall and equal distance from each speaker, thus creating a triangle.

That would ONLY be a starting point and would unlikely ever to be the best place except in a 'perfectly' designed room. For example, in my room which has a length of 19.5 ft my speakers are 66 inches from the wall behind them and my listening position is about 60 inches from the wall benind my chair.

FWIW.
