Also, you never want to lower the crossover (ok to set higher) from the setting that was configured by your receiver after running Audyssey. For ex, if Audyssey reports back to your Denon that the -3dB point of a particular speaker is 80Hz, the Denon would set the speaker as "small" with an 80Hz crossover, as Denon uses 40Hz as the determining factor. You would never lower that value, but raising is ok.
