What is your room size?
I found with my Maggie 1.6 that the Cardas method worked well and the rule of thirds better but was too intrusive.
You can go to the Cardas website to see their formula for speaker placement
on a 15 x 21 room the rule of thirds is: speakers 5 feet apart (15 divided by 3 =5) and 7 feet out in the room (21 divided by 3 = 7)
good luck
