[QUOTE="Cliff459, post: 8259511, member: 660957"] Just a thought here: Why not try to repair the broken crossover? Many times there is just a broken solder joint on the circuit board due to rough handling during shipping; inductors are heavy components and a hard hit that causes lateral motion of the board can shear something like this off. Over the years I have repaired many pro audio type speakers used in concert audio reinforcement with this type of problem. Sometimes it is just a defective solder joint that once touched with a hot soldering iron it re-flows and gets a solid connection to the circuit board again. Marginal quality solder joints sometimes happen during modern electronics manufacturing and sometimes still manage to get through the QC process.

Given that, I would suspect that the crossover is quite simple containing only a capacitor and inductor for each of the drivers. There can be an impedance-correcting network for the woofer that is called a "Zobel Network", but since there's nothing mentioned in the Morel literature I assume there isn't one in these crossovers. Here's a web page that shows some passive designs with various crossover "orders" and how they are wired.
