I know this is old, but...
I just bought a pair of ST III/SE and have been checking out the wiring as I got all the Focal T-120's new surrounds as well as the smooth 10" woofers.
The resistors in my speakers are wired one in series and one in parallel with the RIBBED 10" woofer. So, James said the post of Stimpy is correct (#7), and the OP's (#28) is not, but he has the resistors as connected to the smooth woofer. My guess is Stimpy's labeling of the smooth and ribbed woofer is incorrect simply because the ribbed one is on top of the smooth one and he has them labeled the opposite. Do you all agree?
Also, my wiring matches the OP's however I do think my speakers had been worked on at some point. My crossovers are very well soldered and neat, so I'm thinking Brian did them, but one of the white 15" woofers has the sound absorbing stuff on the basket, but the other doesn't.
Also, the Focal tweeters, while electrically wired the same as the OP's, are physically placed in different order in the left vs the right cabinet.
Thanks for anyone's comments!!
