The JBL has a passive crossover built into the cabinet but there are connections on the back for separate driver hook up. At first I used the JBL XO and just disconnected the mid-range horn in the JBL and connected my AH300 horn instead.
Then when I got the dbx, I ran out of my preamp to the inputs of the dbx and then on to an amplifier that drives my horns and another amp that drives my woofers. Currently I have replaced the JBL woofers with a pair of RCF L15P530 woofers. The only thing from the JBLs that I still use is the box.
My crossover frequency between my woofers and my horns is 300 Hz. I use a 24 db/octave LR filter in both directions, one half meter of time delay, and a small amount of shaping. I'm sure I don't have it optimized but I'm quite happy with the sound overall. Does this explanation make sense?
