Speaker placement

Go to the cardas site they have a room formula there all you have to do is plug in the width of the room and it will give you the exact spot from the back wall and the sidewall to put the speaker I tried it and it works beautifully.

Thanks for the help everyone. It’s greatly appreciated ! 

In an Audiogon discussion I came across the  “Allison Rule” of speaker placement.  The poster described it as follows:
The Allison rule basically states that the distances from the woofer to the floor, woofer to the side wall, and woofer to the back wall should be as different as possible. To accomplish this, one would apply the following equation:
Middle distance squared = shortest distance multiplied by longest distance.

Example:
22" (floor to midpoint between woofers, a fixed distance)
57" to side walls (about as far as I could get without bumping furniture)
36" to front walls (the "middle distance")

Compared to Cardas and a couple other formulas, this one seemed to offer a better compromise with practical furniture placement needs (in a space that is not a dedicated listening room). 

Over the years, I've tried numerous speaker placement methods and the Odd Dimensions Placement, advocated by Richard Vandersteen, has always worked best for me. 

Another good trick I learned was go to Axpona in person if you can or use web site to look at how the rooms are set up. You will see more of them using what I call the corner unequal triangle set up. There is an article out there on this but I can recall where it is. This is used to increase sound stage a depth when you have a difficult room configuration or listening position. In general the system is in the corner apex and one speaker is placed in a forward position and the other is further back. Sorry I don’t have more detail as I read in a very passive way knowing I did not have to do it in my room.
