Hello, I am working on the layout of a new HT and have a question concerning rear speaker placement and angle. Due to the spouse factor I will be using satellite speakers mounted on a back wall. According to the Dolby site these speakers should be facing each other, but I have heard this may not be necessary. So my question is what is the correct way to mount satellite speakers on a back wall? Is there a proper way? Is there an angle they should be set at? Any help would be greatly appreciated.
