    Spec sheet 2121 lost

    I never had one spec sheet from the 2121.
    Giskard posted that he lost his.
    Who can help?

    I'm interested in the SPL and impedance curves.

    Thank you, Guido

    Re spec sheet

    I'm just interested in the curves!

    For comparison with other 10" midrange drivers. If you have a spec sheet for 2121 and/or 2122H please post it or send it to me.

    For my 4343 project I'm fine until I tested the 2012. Will let you know the results. At the moment I'm waiting for the K140 to be reconed to 2235.

    The 2121 spec sheet is NLA.

    Sorry about having to delete the graphs. Hope you got them downloaded while they were posted.

    Wow!

    Hi Giskard!

    This time you surpass yourself!

    Thank you!

    Where do you get all this from?

    Don't tell me the Delphi story

    A big hello from Germany

    OK, I'll bite...

    How 'bout the venerable 2245H?

    Pretty please?

    Thanks !

    Thanks ! Giskard, for the reponse curves .

    Interestingly , my blend of a le14h & le10h-1 / paralleled together on each side (MTM) / shouldn't work as well as it actually does / strickly according to the sensitivities stated . I suppose actual AC impedance differences & the relative vertical placements, is making up the apparent sensitivity difference . ( In fact , I've had to dial back the le10h-1 by adding a series, 1 ohm resistor - sometimes also, an inline inductor to reduce that midband rise .)

    regards <. Earl K

    A hearty THANKS, Giskard, for the 2245H plot - timing could not have been better!

    Snagged it before the Post Police called on us...
