As far as I can tell, all I can do with my AVR65 is set the main speakers to large or small. Doing so will either send full range audio to sattelite speakers or only what is above 100hz. So basically, the subwoofer's setting has no effect. In fact, I tend to think a subwoofer's control can only affect what it plays back, not what it draws from the receiver. Maybe I am wrong on this one?

80hz sounds good. I wonder if I could buy an HK AVR435, try it out and if I don't like it send it back? I hate being a flake like that though.
