It seems that generally, most people have set their front mains to 80hz if Audyssey comes in below that. I understand why. But what about the surrounds and rear surrounds? Do most people just leave the crossovers that are set by Audyssey for those speakers? Should it be 80hz all around? My room is pretty narrow in front, and opens up in back. I am using in-wall speakers and a traditional 12" down-firing powered sub. Audyssey always tends to set my f/l mains at 60, center at 40, surrounds at 110, and rear surrounds at 120. Setting my mains to 80 makes a big difference. Just wondering what others have done for the surrounds.
Remember the rule--never lower a crossover that has been set by Audyssey. So, leaving your surround crossovers at the 110/120Hz values would be appropriate.
