Solved! Pushed tweeter cone back in - not working anymore...
Hi, i got a pair of Mordaunt Short MS5.20 speakers for free a few days ago. The only problem is that the right metal tweeter was pushed in a little bit, but worked fine.
Being a tad OCD, I unscrewed the tweeter and pushed the diaphragm thing back from the inside like I have done with a few other speakers. However, when I put the tweeter pack inside - it does not work! A spare tweeter for another speaker I had lying around worked fine however...
Is there anything I can do to try and repair the tweeter? I don't have a multimeter lying around, so cannot test for impedance :'(

Metal dome tweeters are fragile and so to the voice coil. Its a pretty safe bet you have fractured the very fine voice coil wire somewhere.
I just found the coil had become disconnected at the terminal to connect the tweeter up. After twisting a few copper strands onto where the wire broke and securing it in place with blue tac - it's fixed!
Thanks
Sometimes a tweeter can sound slightly better with a small dent in it by strengthening the dome against breakup modes. I'm not saying it's something you should do regularly though
I'd recommend soldering the strands, otherwise vibration and contaminants may upset the connection. You should use a hot iron and avoid solder wicking up the leader and solidifying it.

Next time use a vacuum cleaner.
Sounds like a bad idea on a metal tweeter...

I'll solder it in a few weeks when I get around to buying a new iron, my old one let out it's magic smoke...
