* The outputs of first order xover filters will add to exactly the

be enough, depending on the application.

* If you want steeper (higher order) filters one solution is to
us the Linkwitz-Riley type. Outputs add to a perfectly flat
frequency response, but the phase response of the recombined
signal is not linear. It won't matter in most cases.

For ready-to-use L-R filters, get zita-lrx1. It provides up to
four bands using 4th order filters (i.e. 24 dB/oct).
