Title says it all, but is there a newer version of the 10" JBL 2123 or is this the latest incarnation of this midrange driver?
TIA

Thank you but I see that it is discontinued too. Is there a currently available, new successor?

At a guess I would say the 2251.

Allan.

But 2251 efficiency is about 1dB less then 2123 applying 1W/1m,
but if voltage amplifier used applying 2.83Veff then
the difference would be about 6dB ~ 7dB

but as presented on the (round 600HZ):
2251 ( 4.06V):
http://www.audioheritage.org/vbulletin/showthread.php?17040-2251J&p=172623&viewfull=1#post172623
so SPL level (1m) would be round 96dB, and if reduce -3dB that would correspond to 2.83V so SPL(2.83v,1m)=93dB
2123 (2.83V):
http://www.audioheritage.org/vbulletin/showthread.php?29742-2123&p=298699&viewfull=1#post298699
SPL(2.83V,1m) = 100dB
