It is not really sound positioning. It is a big room, but has a pool table in the middle. When not in use, I put the speakers VERY close to the back wall. When they are running, I pull them at least a foot away from the wall. I know when I bought them and about the rear porting. So, I just have have to live with moving them back and fourth. Not really a big deal, but I am looking at options.
