I am looking to purchase one these this fall when the price drops and am also looking to go with active crossed separates. Was hoping I could use the receiver to power tweeters and use other amps and mini dsp for mids and woofers. MY question is what crossover frequencies are available for the speakers using the receiver's amplified channels? Could all of the powered outputs be set to 2500Hz or 3KHz (or other chosen cross point)or does the audyssey limit it to small, medium, large settings? I thought since this was a top of the line receiver it may allow more user manipulation.
