I tried to follow Arve Bersvendsen's placement ratio recommendations for my room (first link) as it seemed the less complicated and more versatile of the various placement methods described, and it really improved the sound of my system in my room. I did the best to adhere to one of the recommended placement ratios that worked with my room shape and furniture placement, and then moved the speakers slightly from there and played with toe in to fine tune. You will know when you get it right because you will have an immediate "Now That's What I'm Talkin' About" moment.
I also found his test CD with 63 different tones useful to see where frequencies were dropping out or being enhanced. I even bought an inexpensive digital sound meter from Radio Shack to assist my ears in this exercise. Aside: it is remarkable the difference between these measurements taken 1m directly in front of the speaker baffle versus from your listening position. Even when the speakers are well placed and sounding good, the frequency response at my listening position is far less flat compared to right in front of the speaker itself!
This an inexact science at best, but careful placement can make a huge difference in overall system performance, your happiness, and the resultant longevity of gear in your listening room. :-)
