    Likely a useful service for those not interested in tinkering with their own.
    Seems this service was discussed or noted before.

    Removing or attenuating an offending frequency band, is certainly an option
    but it would also be reducing performance capability/potential, so it does have the
    appearance of a band-aid fix. I’d guess VSN would agree.

    Hey Brad,

    I told you that the problem to refurbish the JBL 044Ti damper pad is the diaphragms and they are glued at the factory.

    Because numerous of enthusiasts like you, I looked at the 044Ti tweeter situation once more and I am developing a new technique to refurbish the foam!

    I’m excited to tell you that very soon I’ll list my JBL 044Ti Tweeter Refurbish Service for 250Ti, 240Ti, 120Ti and 18Ti speakers.

    The bad news is the challenging labor, and you can recognize that time is money…..

    Look for my new listing in August,
    VSN

    The diaphragm assembly is lightly glued onto the magnet plate, yes. Perhaps more of a tacky substance, just enough to hold it in place during assembly. Ordinarily it would not be a big deal to work it off without totally destroying the assembly but complicated by the need to be extremely careful with the voice coil sitting in the narrow gap. I can understand anyone's hesitation with taking this on since there are no fall back replacement parts. I have not tried this but at one time I was considering how fishing line or something more abrasive would work to "floss" the glue joint apart.

    Here is a post by someone doing the disassembly. It's in French but you get the gist.

    I suggest taking it to an outfit who does driver rebuilding and repairs.

    They have access to every conceivable voice coil ect and can assess and the do this job.

    The loudspeaker manufacturing industry has a huge parts inventory they can access.

    In my area l know of two people with over 30 years of experience who do this kind of work.

    If they say it needs whatever done then pay the charge. If they say it can’t be fixed start looking for an alternative.

    It might be worth contacting GordonW
