I put mine up on a audio stand that just happened to be the right height, just above ear level and tried them in several places. I started with them directly to the sides and then kept moving them back and kept going until they were all the way behind me on the back wall, about 8 feet from the listening area.
My experience was that they sounded best along the side wall where I could see them by comfortably turning my head. I don't know how many degrees that would be but, it works.
