Not trying to be coy suggesting the obvious, but if you pull the bad one from your speaker, it doesn't happen to have a label or any other markings on it?
Also, when pulling these drivers (and I'm trying my best to remember details from a crossover upgrade thread on the old va321 forum), since you can't push them out from the back and they can sometimes be stuck in pretty tight, the best advice I had seen to avoid damaging the cabinet finish was to use an allen key or something like a spring hook to hook the driver from inside one of the screw holes in the frame and pull it out that way.
