I posted this in the Speaker section, but didn't get many hits. Thought I'd try in the main section. Is there a rule of thumb for setting speaker distance when it is between settings? I have my center speaker at 9.5 feet. Should I set it up in the receiver as 9 feet or 10 feet? Also, should the center and fronts be the same distance? My front mains are at 10 feet, center at 9.5 feet to be flush with the front of my entertainment center. Thanks.
