I have been experimenting with a variation of using the Golden Ratio in locating loudspeakers that probably is not original but which I do not recall others describing.
Considering the significance of interaction between the woofer and the floor, I used the distance from the floor to the acoustic center of the woofer as the "1" dimension in a 0.62:1:1.62 series. I used the smaller number as the distance from the woofer's acoustic center to the rear wall, and the longer as the distance to the nearer side wall.
I am pleased with the results with my speakers in my room.
This approach will not yield practical solutions in all cases, but I thought it was worth sharing would appreciate the comments and experiences of others.
Follow Ups:
The correct distance of the enclosure to the rear wall is a AURALLY determined position. Lowness of response Versus bass definition and overall character, naturalness.
The closer to the rear wall, the lower the system will couple to the room boundaries, until it couples too closely, and the bass become muddy and ill-defined. One must position by ear, trading off lowness of response to less muddiness, easily sensed in the mid and upper bass' character and aural presentation.
Ultimately, distance increments as small as 1/8th of an inch can be heard in my many 1980's experiences with Fulton Premieres ( 12 HZ to 110 KHZ ).

That's what I said.
:)
So-called "golden ratios" are for amateurs who don't have a grasp of sound and acoustics.
:)
rule that usually works very well is the rule of thirds and it doesn't have to be exact.
I settled on 1:1 woofer to the floor, 1:2 baffle center to side wall. 1:3 baffle center to front wall. Having a system were a large woofer is close to the floor helps.

To get any meaningful results you would have to try other combinations of distances to see if it made any difference.
