I just got it because it works fine, regardless of what graphs show. It was specified for the 7Pi Audiophile model, which in fact was a direct radiator. Mainly, I selected it because of the cost of the new jbl 2012. Wayne has assured me I couldn't tell the difference, which should be slight, and that the 2123 is an excellent choice. I don't know if jbl changed there measuring proceedures between the old and the new, but I notice slight differences between them, including the 2425 and the 2426, which people tell me are identicle. Again, there is certainly nothing wrong with either choice, and no sonic difference will be detected. slight differences such as these, while measureable in a sound chamber, will be dwarfed by room interaction. Myself, I'm not convinced a gradually rising response is a good thing, with non horn speakers it has been my experience it always complicates the crossover design. Even if it appears to better match the high freq. unit, Proper crossover should make it a non issue. Again, I also feel the differences between the drivers is so slight (except for price) it doesn't require adjustment. High efficiency speakers have a tendency to shout already. If money were no object, I would go with the new driver from Wayne. Email wayne for his thoughts. either jbl driver will be superior to the other eminence and so forth "stock" drivers, which truth be told probably would work just as successfully as either JBL.
I never found 2012 used, and the new price put it out of budget for me.
the 2123 is legendary and has been used in alls sorts of applications, from direct to horn most successfully. I'm sure you will be happy with 2012 as would I if I could afford the blasted thing!
