Actually I don't have Audyssey. It's the AVR 1513. But the crossover freq on the reciever is of no mystery, 80Hz is clearly where it's at for all my speakers. And I have plenty of bass, esp given the fact that I live in an apartment, I have to be carefull at night.
My main focus has been at this piont, as to what settings to set inside Windows 7. Sending a full unmolested signal by setting my speakers in Win7 to "Full Range" makes sence to me though. While playing music, setting the speaker config in Win7 from 5 vs. 5.1 however does not seem to have any consiquence either way. I think the reciever is handeling all the crossover processing.
