I have the schematic for this crossover but cant figure out if its a 2nd or 1st order x-over. Anybody have an idea? Thinking it was a 2nd order and looking up the transfer functions of 2nd order hi pass filters I figured I needed to add 200 uf to the 39 uf in there. Is this right?
I should add that I use a dBx Driverack Pa as an active x-over with bass to panel crossover @ 300hz. But I believe the purist highs I have ever gotten is via the ML III passive x-over which is set to cross over @ 120 hz. I tried passives for highs and dBx for lows but there is too much overlap @ 120, So I'm looking for an easy way (add a cap here or there) to revise the Logan x-over to give me 300 hz for hi-pass.
