# Need help building a crossover

I need to make a crossover.. nothing fancy or anything... I remember in
college we went over how to make a crossover and I think it had something to
do with a resistor and a capacitor... Anyway, here's what I'm trying to
accomplish...

I have a bass rig and the cab only goes up to 5kHz... I have a component
system; meaning I have a preamp and a separate power amp... I want to insert
the crossover between the pre and the power so the power amp isn't wasting
its time with frequencies that the cab doesn't even support... I need it to
crossover at 5kHz and slope at 18dB/oct... Any help is good help... thanks
again

You don't want a crossover, you want a tone control. Try a low-pass filter -
the simplest is a resistor and capacitor, and you can add a transistor or
opamp, and it gets more fun from there!

just google for tone control or low-pass filter.

Cheers!

Your bass doesn't go much above that anyway (and that's why the cab
doesn't support it)
A filter will just muddy your sound, think of it as rolling your tone
knob down. You won't be gaining anything, really.
