I have a Denon 2808. Anyone know if changeing the main crossover point affects the Auddyssey tune or does it self adjust everything, i.e. if it crossover over the mains at 150hz, and I change it to 120hz, will to cause a lot of issues? Will it readjust the Audyssey and Audyssey flat EQ values? Just trying to figure out what I can and can't adjust without affect the Audyssey tune much.
