Has anyone lost a KEF tweeter?

Where did you last see it?

I'll add that there are good things and bad things associated with being a physicist and an engineer.  First, you can never fully enjoy action movies again because your brain keeps pointing out all the things on the screen that violate the law of physics.

But may people think doing technical stuff is for other people that they'd prefer to pay--implying that such stuff is beneath them.  But it sure is nice to be able to fix your own stuff.  

Assuming it's your tweeter, and it probably is, I'd pick a pair of aftermarket tweeters that I considered an upgrade and install them. I probably wouldn't wait for KEF to provide a replacement tweeter.  OEMs are notoriously slow with parts.  Of course some big OEMs, like KEF, may make their own tweeters wtih a unique footprint making it hard to change.  I upgraded my tweeters in my current speakers to Be and it was a 30 mintute ob to solder them both in.  They weren't cheap, but it was a good change.

Jerry, KEF use that UniQ tweeter inside the midrange design. I’m not even sure there’s a safe way of removing the outer ring without mucking it up. I’m thinking it’s just a snap in plastic ring, but.

This may be more the way you think about it. I think most are thinking they 1) don’t want to void their warranty, if applicable and 2) don’t want to screw up an expensive speaker if removal of the driver is more than just turning a few screws, which is likely the case here.
