J, you have the Epic 60/500 system, correct?
I have my crossover setting on the fronts set at 60 with the center and surrounds set at 100, these particular figures came with a fair amount of playing around and tweaking. My sub is set to 'bypass' to let the receiver handle all of the crossover chores and the trim set to 'flat'. Keep in mind that I am running 80's and have an H/K receiver but these figures should set you up in the right direction.
I've bookmarked
this page for my own reference, hopefully it will contain some information to give you a helping hand.
