    Newer version of the JBL 2123????

    Title says it all, but is there a newer version of the 10" JBL 2123 or is this the latest incarnation of this midrange driver?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

    If we knew what the hell we were doing, we wouldn't call it research would we.

    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/vbullet...l=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/vbullet...l=1#post298699
    SPL(2.83V,1m) = 100dB

    regards
