    Le14h-1 top plate thickness

    Can anyone confirm the top plate thickness
    of the le14h-1. .280?

    xmax = 5.97mm
    5.97*2= 11.94mm
    .280 = 7.1mm
    is the vc depth 19.1 anyone
    19.1-7.1/2=5.95


    Is the vc depth missing a decimal here

    The le14h shares the top plate along with a
    3/4 magnet with the 2235h, 2205h, etc
    (.281) tp is this correct

    JBL often measures xMax as the amount of travel required to reach 10% distortion. Sometimes xMax is published as measured full travel instead of one way.
    All the LE14's that have the thickness specified are ~.28", but that's the -3 and -4.

    You trying to franken woofer a LE14H-1 out of a 2235?

    With the 4315 one I'm doing yes I think
    I'd like to have a set of le14h's to go with the le14a
    i have seen some le14a baskets reasonably
    priced, the top plates on both are .280
    an use 3/4" mags. So this gives me an impression
    they both use the same magnets n have the
    same gap. The 2205h is on
    that list as well, they are sub $40.00 to date. Le14h
    i have seen are priced over $350.00.
    Seems more economical to build a set IMHO.

    from this thread

    Voice coil length is 19 mm (0.75") Top plate for all those LE14Hś are .280" if remembering correct Voice coil is over-hung in those LE14Hś
    But I dont think it is for the LE14Aś (with Alnico motor)?

    In this link X-max is specified to be 8.5 mm I also found this old post from 4313B:

    Idk there is a few developments down there and a few homes
    Trucks are still passing.

    I read them then I will have another look.
    I'm fairly certain these are the same but
    without a heads up hard to be sure

    yes the Vc are the same, in the 2235h & le14h

    does anyone know if the 2203vc is the same as the
    latter depth and gap are equal
