I don't know for sure, but it might be a good idea to re-run Audyssey after you change the phase of your sub.

As far as the crossover goes, it's always been my understanding that you should turn the crossover knob on the sub as high as it will go and use the crossover setting in your receiver. The idea here is that the sub will basically use whichever crossover setting is set lower. An example would be that if your receiver's crossover is set at 80 Hz and the crossover knob on the sub is set at 60 Hz, then your sub will only play up to 60 Hz. The problem this presents is that because the receiver is set at 80 Hz, your regular speakers will start to roll off at 80 Hz as the receiver begins to transition the sound over to the subwoofer, which is only playing from 60 Hz down. This means you will have a 'hole' in the audio between 60 and 80 Hz. Turning the crossover knob on the sub all the way up essentially removes it from the equation and allows everything that has to do with the crossover to be handled in the receiver.
