I wish to build a pair of JBL speakers, in an 8cu. ft. bass reflex enclosure, (JBL design) using a 130a 8Ohm bass and 175DLH 16Ohm horn, driver, lens. I do not, however, have the proper N1200 crossover. I do have a pair of 3120 Professional crossovers. Would these be a drop in substitution?

I'm guessing that they would work just fine. But then, I really don't know anything about crossover design math.

What can I expect? Thank you.

Steve
