    Hi Dr.db,
    I do not know, but a way of calculation have been shown,so I believe A290 is very similar to the mentioned TAD horn. But as can be seen, all the calculation has benn done applying horn theory.

    Damaged diaphragm....???

    Hey guys,

    I need your advice today!

    I just received new JBL diaphragms for the 2405 and 2441.
    One of the D16R2405 diaphragms looks a bit faulty.
    The wire on the voicecoil protrudes about 1mm at one spot!
    It looks like there has been some dirt on the voicecoil before the wire has been wound on it. Now the wire sticks out at this spot for 1mm....

    Im not shure if this will affect the function in any way!?
    But I do not know how tight the magnet gap is and if the voicecoil will scrape in it.

    If it's just the coating, it can be reduced in height. I've had a few diaphragms with that issue. Looked worse than it was.

    You may also want to see about a return if it's new and don't want to potentially void any warranty you may have.

    No, actually there is one winding of the wire on top of that bulge.

    If it was coating I would use sandpaper and wouldn´t worry....

    Mighty impressive build! If they sound as great as they look you have a great pair of speakers.
