This is what you need to know - these are the equations you need for a passive line level filter:

You also need to obtain the input impedance of the power amps in order to calculate RC values.
There is a caveat: The combined input impedance of the power amps must be at least 10 times the output impedance of the preamp. Otherwise the load will kill the sound of your playback.
BTW - what is your opinion of the delay capabilities of the DBX crossover?
Sincerely
Kris
