Anyone try Audio Physic's LS placement philosophy?

Recently I was reading Stereophile's older review of the Audio Physic Virgo loudspeaker on their archives. The reviewer (I think M. Fremer) went into some detail of the manufacturer's "grid" system of mapping out a room for purpose of placing speakers. I found the explanation in the review a bit confusing however. Has anyone tried this with good results? Where can you find the philosophy on the net with better detail?
Thanks!
