Are the drivers for RS750 RSC100 the same?

[Sandbagger]

RSC100 drivers I am almost positive are 16ohm and the RS750's are 8

I found a used RSC100 for sale for $100.00 I have one bad driver on my RS750 and have been looking for a replacement driver. It's one of the woofers that has gone bad, I do know the tweeters are not the same?
But I might be able to save the tweeter as a backup for my RS300 if they are the same also?

Thanks in advance
