Mirage SM-3 crossover question?

I don't expect anyone to be able to answer this since the speakers are about 30 years old but I have a pair of Mirage SM-3s which appear to not have the original woofers and crossovers. They do have the original Seas tweeters and I would like to try to restore these to what they were supposed to sound like originally if possible. If anyone knows the original model and manufacturer of the 10 inch woofer used and also the crossover points etc. I would be much obliged.
