@j_garcia, thank you for the reply! Currently, the speakers are currently 8" ahead of the TV. Because I will be moving the stand back a bit and the new TV is thinner, the new TV will be approx. 12" behind the front of the speakers.
The treatments behind the room are actually part of an overall room treatment for controlling echoes in the room.
I agree moving the speakers farther apart would be ideal, however the issue (even if I had another place to put my rack) is that because of how the room is laid out and the fact that the listening area cannot move, it would mean that the left speaker would become about 2' farther away from the listening area then the right and it would also mean that the television would look strange in the room being off center between the speakers because currently the TV is centered with the listening area.
Thank you for your input and suggestions!
