I saw this ebay auction a couple days ago, and emailed him about it. The auction is still up...
These are NOT JBL drivers... take a look at the phase plug, No annular slits! Round holes instead. Accepts a JBL or aftermarket clone diaphragm.
I have several JBL MR Series speakers with 2416H drivers, and none of them have "holes" in the phase plug like this pic.
I saw a pair of these same drivers on ebay awhile back, and knew they were not. I cut'n'pasted the pics from that auction into an email to JBL PRO Tech support. The next day, they confirmed with this reply:
Dear Rudy,
Definitely not JBL component. I asked around to see if anybody might know who made this, and it seems to be a Radian, but not absolutely sure.
Hope that helps,
Best Regards,
