By the time you're done fooling with this you'll end up replacing the whole driver anyway (or should have, based on how much time you'll put into it).
In this part of the world, these things are eye wateringly expensive so the "just chuck it" philosophy does not apply. I'm prepared to do quite a bit of "fooling" to recover this item.

Expensive? That's a $1000 driver. Call Charlie Tappa at Pro Sound Service. He'll put you in the right direction. Best JBL shop in the USA.

I did a gig for Otis Elevator once. Like every job, it had it's ups and downs.

I was going to say, most cyanoacrylates are pretty brittle.  There are a few "toughened" ones that are okay for dust cap or voice coil attachments.  The strongest adhesives I've run into are the acrylics.  Good old Speedbonder 324 was the first.  Now there are bunches.

Most of the adhesives industry has been gobbled up by Henkel of Germany.  I'd suggest to the OP to peruse their site and try to find a local rep who can get back to the factory experts on suggestions.  It's a good bet that JBL is using some Henkel product under one of their many brand names.  Finding the right people might lead to a suggestion as to "people like you are asking about probably use something like this".

That was my first call - Kelly is unsure whether his magger can handle this item, which is why I canvassed the larger community. I'll find out tomorrow :-).

Update : Axent's speaker guru threw his hands up in horror when he saw this driver and said their magger would not do the job (despite it looking like it weighs about 2 tons and is an escapee from George Westinghouse & Tom Edison's laboratory).
