Re: Eliminating an active crossover


You don't need any filters above the crossover, your prepro with an 80Hz xover is doing the same as your active xover with the same setting. Just try some boost at around 25Hz, bandwidth around 1 octave, so that the "corrected" trace of your measurement without the active xover is more or less overlaying the trace of your measurement with it. Looks like it will need about 10 or 12dB of gain to do that. Then you can start putting in some filters to deal with some of the peaks at 45Hz and up.
