Hi there, about to build a pair of ported 90l eminence lab 12 subwoofers tuned to 24hz. Want to power them with a Behringer ep 2000.
Anyone know the easiest way to set up an adjustable low pass filter (like the variable knobs on active subwoofers eg 50-100hz). Also want to have a fixed high pass at 20 hz. Input would be line level.
I would be grateful if you could tell me the easiest way of doing this. Thanks.

A 2pole active low pass filter will do the job.
You can use many of the opamp circuits to achieve the adjustable frequency by substituting a VR for a fixed resistor. For some circuits you will need a a 2track pot if you want to maintain the same filter Q.
Try esp for some ideas and solutions.
