Thanks for your response. The Outlaw ICBM is advertised as having a "2nd-order Butterworth" high-pass and low-pass. I don't understand the terms and need to do some reading.
Part of the reason I like the external crossover idea is so I can have short cables between pre and power amp sections. I get the impression this is important if I end up with a passive preamp (e.g., Creek integrateds)
I'm guessing a passive high-pass filter, like this ACI product, leaves something to be desired?

Otherwise, couldn't this could be combined with a Y-splitter?
