    Original cone kits have a coated foam.

    Everything else is -refoamed- or -not original- or -...whatever people do with woofers-.

    Yes, of course!




    I don't think these will ever come. Use an Radian 475PB-Be (with 1,75" Beryllium diaphragm). VERY good and not expensive.

    The main change was the fixation of the vc leads and some corrections to the attachement of the diaphragm to the vc.
    Older diaphragms could have issues with rub/centering.

    If there is a 4" bolt circle on the adapeter plates it was very likely made for a driver with a 4" bolt circle (e.g. Radian 951PB 1,4" exit). Makes sense, or not?

    It is the point.
    The improvements you try to get occur in an area where Ti/AL dias do no longer work (show piston behavior).
