A passive crossover is just a pair of high-pass, and low-pass filters with similar slopes. It's not one device which sends the bass in one direction and the treble in the other. It's the full circuit network which gets the name, "crossover."

I think (never have looked inside) that with the way Axiom has the removable straps between the "bi-amp" posts that they have designed their network like you're asking, Adrian.

So it goes:

One input into the low-pass to the woofers.
The other input into a high-pass for the tweeters.
The other input also split into a band-pass for the mids, but the band-pass itself is a pair of high-pass and low-pass filters paired together.
