    Expect more photos to come, and response measurements once I make a proper horn or adapter.

    part number is 5020810X
    Nice

    What kind of horn do you plan to use?

    Can this CD be used in a 1" exit horn? I assume no, but assumptions are often wrong.

    It is supposed to be a 0.8" driver.
    In the long run I'd love to use it with a 8" driver underneath (synthesis 8 in a 2 way, or maybe 2250HPL in a 3 way) with a 1/2 scale M2 horn: http://www.audioheritage.org/vbullet...l=1#post379272

    But first I will most probably make a 0.8"/1" adapter with a flare similar to 242x drivers.
    The only bold-on 1" horns I have here are the 2344, so I might as well try that.

    I received the units.
    They are surprisingly tiny !

    Exit is 21mm, bolting pattern 40mm, 4 screws.
    Still have to determine the screw diameter, which is not an easy task when you only have metric screws at hand.
    Inner diameter is around 3.6mm/0.14", if that rings a bell to anyone more used to imperial screws than I am

    With impressive size-to-"noise"-ratio then, I presume

    Let's hope they can do more than just noise

    I'd guess #8, #8-32 is a pretty common size here.

    Reminds me of the Weber side drafts on my old coupe. They look like they mean business.

    This driver is now used in the just released SCL-2 :
    http://www.twice.com/thewire/harman-...ise-2017/64254

    The SCL-2 is designed with a 2.5-way, triple 8-inch (200mm) driver configuration for low-frequency extension with high output capability and powerful dynamics. A D2415K dual voice coil, dual 1.5-inch (38mm) annular ring diaphragm Teonex® compression driver with advanced HDI geometry horn works in conjunction with powerful cast-frame, 8-inch (200mm) Advanced Aluminum Matrix cone woofers with low distortion motor structures.

    The older SCL-3 and SCL-4 use the tiny 2409H driver already used in the 705i/708i

    The SCL-2 seems to be exactly what I described here :

    Perfect fit for a 8" woofer...

    Here are some pictures of the new SCL-2, alongside the SCL-3 and SCL-4, courtesy of Skylinestar on the AVS forum :

    A guy here were on ISE show were they were JBL running 3xSCL-2 in front and SCL-4 elsewhere and 4xS2S-EX. He was very impressed and had no doubt that JBL were "ISE best in show".

    nope
    I was to busy/lazy to build the 0.8"/1" adapter.

    I will put this on hold for now in the hope of seeing it appear in the install series with a detachable (and available!) HDI waveguide.
    I doubt the baffle of that synthesis speaker can be obtained as part (or can it?)
