@dmaddox77 , if you want to widen the dispersion you can place 2D diffusor or combo panels on the front wall between the center and L and R channels (again you can see the example in my pic).
Remember, when you get the trinnov the room correction can be used to assist. When you take measurements make sure to take a couple where you seem to need more coverage.
If you post pics of your room it would help if we can see.
