Speaker placement for music & movie?

Hi, Are there any rules or formulars of speaker placement in order to get the best sound for both music and hometheater? Thank you very much DT
I don't have any formulas, but my approach to the same question is put the speakers wherever they sound best for music and use the processors adjustments to get movies dialed in from there.
I got some great info. to basically the same question in my last "thread": OPTIMUM SPEAKER PLACEMENT just last week. Take a look, there are several sites suggested. Ken
