slightly pushed in softdome tweeter on Fritz speaker

The best trick is to use a shop vac... I had a nephew brat totally poke and crush in a aluminum dome tweeter.. I was pretty angry, I tried blue tape to pull it out and it kinda worked but not that well, then I grabbed my Milwaukee cordless M18 shop vac and used that and it got it almost perfect without touching the dome... I think it would work even better on a silk dome 

I'll keep that in mind,Thanks. Hopefully not repeated on my end ever again. 

You can gently using your finger just push it out and it pops back in to the original dome shape 

This happened to me once and I used the tape method mentioned by someone earlier and it worked great and the risk factor was super low. That's why I +1'd that method. 

I was always leary of the shop vac method, unless it was a variable speed motor, I always just pictured the suction being too strong and just demolishing the cone. Never personally tried it though, just my wild imagination.

Well, glad you got it resolved and cool to see everyones suggestions.

I purchased a pair Tannoy dome supertweeters that were deeply discounted because of pushed in domes. They’ve a gold colored coating. The coating’s function is not known to me. Tape worked well but damaged the coating. I next tried the shop vacuum. Success with no further damage.
