Help for Linn Isobarik speakers

I am the original owner of a pair of Linn's Isobarik speakers, purchased back in 1987.  They were in perfect working condition until last week when a painter moved them away from a wall and squashed the top tweeter of each speaker in the process (despite my earlier warning).  These speakers, once one of the finest in the world, were still proudly anchoring my second system and I would love for them to continue to do so.  I'm pretty sure Linn ran out of replacement tweeters long ago, so my question is, what is my best option for repair/replacement?  Sound still emanates from them, but it is obviously compromised.  Also, assuming there is an appropriate replacement tweeter out there, is this a job for which I need an expert or can a laymen, such as myself, do the job?  I'm pretty handy with a screwdriver!

Great old Linn Isobarics, need to be hard against the back wall, don't image well, but sound great.
Get in touch with these guys, they’ll sort you out, give them the serial nos. on the back of the speakers, when you talk to them. You can change out the tweeters, just note the polarity before disconnecting the wires

If its a soft dome like in the picture it might pop back with just a little suction. The soft domes on mine were dented during shipping. One popped back on its own, the other with just a little help, with just a slight wrinkle that disappeared in a few days.

Thank you for your feedback.  The suction concept sounds too good to be true, but I'll give it a try.  Assuming that does not work, I will contact Falcon acoustics and Wigwam as suggested.

Careful using a vacuum suction on tweeters, it’s too brutal for tweeters, it works for bass driver dust caps but tweeters are very delicate, I’ve seen the ham-fisted suck the diaphragm/voice coil right out of the tweeter housing.

Use a pair of tweezers with a piece of good sticky tape or I’ve even seen warmed up sticky blu-tack work also, stick into the middle and gently work/pull it out the depression, but from your post they sound trashed.

Thanks for the warning about the vacuum.   As soon as I have a bit of time, I'll try the sticky tape solution, though I think they may be too far gone to save.
