One thing that some people have done incorrectly, is that none of the measurements should be taken "outside" the locations of the speakers. You want to create a bubble around the listenting location. Taking a measurement outside of the "box" of where your left/right speakers are, for ex., will result in poor results. J.B. pretty much summed a lot of things up. I'm to tired right now to type to much. Been painting the theater.
As J.B. mentioned, any speaker that was set to large by your receiver, (not Audyssey), should be set to "small". It is ok to bump up the crossover point, say from 40Hz to 60 or 80Hz. But, you never want to lower the results found by your setup.
