DanF,
The Onkyo 595 does have bass management. I can set all speakers to "small" on the Onkyo and that will keep the receiver from sending the full frequency range to the satellites. Is this the kind of filter your talking about? It probably won't be as well matched as the klipsch amps, but it shouldn't distort if I set my receiver speaker outputs to "small".
Anyway I'm going to try this, if it doesn't sound as good I'll just have to get different speakers, but I was hoping I could use the pro's with my receiver without having to use my computer.
Thanks for the help,
