    - ( 3 & 4 ), Huh ?

    - Obviously, your understanding of this is somewhat muddled .

    - These are your drivers according to an earlier post by you .

    - FWIW, once you put a 23763 diaphragm into any one of those 4 drivers it becomes the functional equivalent of the 288-8E driver .

    & BTW, these older ( pre "G" ) magnetic assemblies just don't have the magnetic juice to be called the equivalent of a boan fide 299 / no matter which diaphragm you stick into them .

    So,,,, swap in that 23763 diaphragm ! ( or are you just not comfortable doing that ? )

    - If not, have Pano work on it .

    <> cheers

    Earl Yes I know !! They are all 288C drivers I am just describing them that way just to distinguish them between drivers 1&2 and drivers 3&4 for reference only.The G,H,etc.. also had 30 Lb mags were as the C are 20-22 or thereabouts.

    Drivers 1&2 were converted from 24 ohm's to 8 ohms with a 23763 diaphram
    Drivers 3&4 were converted from 24 ohm's to 8 ohms with a 25884 diaphram

    That's it, they are still 288C drivers.If I didn't people would assume they were all the same "Would They Not". Drivers are all the same just different Frams.

    For our purposes we'll just call them 288-8E's

    Which reminds me. I forgot to send you the centering shim. All packed away now while the room is under renovations. Gotta to see if I can find the spare.
