active crossover recommendation

Bryston BAX 1 crossover

I have one pf these.

the selection of crossover points is up to you and new/different ones can be ordered and replaced.

The bryston wont work. None of the suggestions will work

Check out the DBX units. I realize they're a A/D then D/A, but with all those possible adjustments I wouldn't worry about the digital conversion. This will be your best solution. Don't fear the digital processing as it's more accurate than the analog versions, and a whole lot cheaper.

Hey OP!! Depends a lot on your needs.

Most passive crossovers include level matching, frequency and equalization.  If you need equalization a DSP based unit like miniDSP would be ideal.
