btw, once again, the dolby document does not work well for small rooms. (marti, no need to comment, I know you don't agree). They only work for small rooms with wide dispersion speakers (and at least 10 foot of space between listening spot and speakers), which most small rooms from what I've seen won't be using.
The rules dramatically change once your speakers are less than 8 feet away, and are 45 degree or more spread out from listening position.
This is the guidelines that we're using at our company, and they translate well. Use at will, or ignore. It doesn't matter to me :)
