Surround Rear speaker set-up 5.1


I am really limited to the back wall.
I would like to use for movies and multi channel music
The sonus walls can move horizontally.
What is the best solution here? I am told it should be on the sides for best results. Does it really make that much difference?

Hard to believe but I am OK with it if you are happy.
