I decided to give Audyssey another try, but I still have mixed feelings about it. It doesn't seem to get the distances or channel levels exactly right, and some are way off. For example, it had my left surround about 2.5 dB too hot.
But my question is why does Audyssey calculate that the distance to my sub is 1.7 feet when it's actually 6.7 feet? Should I leave it alone or change it?

I started out with nothing & I've still got most of it left
