Heads up for the future, check a wiring diagram before you hook up whichever driver you get...if you've got 1200 watts to play with, you don't want to send it to a sub that can't handle it, and with dual voice coils you've got some wiring options to eliminate that risk.
Ascendant may actually be able to recone it too....they MAY have softparts hanging around still for them. No guarantees, but I'd give them a call to check it out.
