I own a pair of l100 with 123a-3 bass drivers and have seen auctions for 123a-1 bass drivers for the same speakers, for all that know any differences or preferences for either ,I appreciate your responses.

Doing a search for 123A-1 or 123A-3 will reveal dozens more threads that you can review.

Most importantly - if you intend on swapping LF's - the 123A-3 is a negative transducer. It's ancestor, the 123A-1 is POSITIVE.
That means, if you are putting the -1 into a -3 cabinet, you will need to connect the RED wire to the Black terminal, and BLK to Red terminal to maintain the JBL factory phasing.
If your L100's have the 123A-3, they are the "L100A Century (Late Model)", and thank dog, the last...
It's been a while since we swirled about Polarity. I think I just got a stiffy! :idea:
Gotta go !! :uhmmmm:
