Active crossover for pair of lab 12 subwoofers
 
Hi there, about to build a pair of ported 90l eminence lab 12 subwoofers tuned to 25hz. 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 both both digitally and analogue. Thanks.

I just went through this but wanted the high pass to protect the subs from over excursion if playing At any high volumes under the horn tuning frequency.
Anyway for $99 plus $10 for a plug in the mini DSP is very helpful (and flexible)

There are plenty of cheap and easily adjustable active crossovers for car use, they'll be 12v powered and 2-way,. They won't have a "subsonic", but these can be easily made on the RCA input side-I have seen a link on here, or get one of these: FMOD (Filter Module) High Pass RCA Level Crossover

What about a Reckhorn S1 subwoofer filter ?
