I apologize in advance if this is a stupid question, but I just bought this receiver yesterday, and it is much nicer and more advanced than the pioneer elite it is replacing. It is my first time using Audyssey as well. The pioneer didn't allow me to set separate xcovers for the speakers, much less this amount of control over the sub. Audyssey correctly set all my speakers too small, with the the xover around 100. But it set the xover at 120 for my sub, and everything is very "boomy". There is tons of bass with everything, it almost sounds like the sub never turns off. I though I read something about setting the xover for the sub at 80, but I wanted your input to see if this is correct. I have the definitive technology 600 series, with the 1000 series center. Thanks!
