This forum is oriented towards building subwoofers, not the electronic crossovers that may be used with them.

Try looking in the Source & Line forums:

Analog Line Level
Preamplifiers , Passive Pre-amps, Crossovers, etc.

Active Filters The 24dB/oct is another option.

Should be easy enough to build.
