high-pass filter (low-level)
 
hi guys,
does any of you know how to make a 3rd order high-pass filter for use at low-level at 40 hertz, and one at 50 hertz?

eeuhm...
i'm not too educated on the subject:) (yet)
it's to be used between a plateamp (subwoofer) and my poweramp. Would this info do, or should i look up the exact number?
