    Prototypes having voice coils with diameters of 1.5-, 1.75- and 2- inches and 1- or 1.5-inch exits have also been developed by JBL.
    Probably a 1" driver. Would be interesting to compare to a 2407H or 2408H !

    Well , that didn't take too long to pop out of the sausage factory. I wonder why the little one needs all those fins whereas the
    big one has none.

    This is the driver I think we will see a lot of in the future. Keen to get info on this as it emerges, Thanks POS.

    There is also a VTX F series of 2 way boxes that might be of interest to some of the gang here.

    D2 inside with a diff drive woof. No prices that I can find yet.

    As far as I can discern it's so far only in the small VTX line array. I'm sure we will see much more of this one as time goes on.

    Good pix.

    What is that yellow wire used for, connecting both positive poles of the diaphragms with each other?

    The voice coils are connected in series so the jumper goes from front negative to rear positive. At least that's how the D2430K's were that I had here.

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

    It appears the D2415K is actually a 0.8" exit driver, 21mm exactly:
    http://www.jblpro.com/ProductAttachm...et_5.12.15.pdf

    The diaphragms are 1.5" rings, similar to the single one in the 2407H.

    It is basically a halved D2430K !

    Now picture yourself a 1/1.8 version of the M2 waveguide, 25cm x 20cm, usable for 1.5kHz and up, and maintaining its 120° pattern up to the UHF...

    I know the D2430K is readily available for purchase, but does anyone know of a source for the D2415K? I think it would be fun so slap a pair into my big ol' SVA's, do a little DSP magic and see what comes of it. If not I might just have to try the 2430's in the same application.

    D2430K compression driver: bolt size?

    Dumb question of the day: What bolt size does the D2430K require?

    I assumed 1/4-20 thread in the standard 4-bolt pattern, but they seem to be slightly too large. Or at least they don't screw in all the way. And metric M6 doesn't fit at all.

    TIA,

    Joel.

    The photo is one of the two units that are on their way to me right now
    Expect more photos to come, and response measurements once I make a proper horn or adapter.
