celestion a2 tweeter blown or not

I have a Celestion A2 floor standing speakers, both tweeters are now silent after I hooked them up to a Karaoke system and started to sing ;^(. I took them out of the enclosure and looked inside particularly at the diaphragm, they both look intact, clean and undamaged. What can be wrong with my speakers ?

Any idea for how to fix it ? Looking for original parts might be a dead-end since these models have been discontinued for years.

Both the Midrange and Woofer still sound very good, seems not being affected. I don't know if anything in the cross-over might cause the tweeter to not being able to function.

Do you have a meter to check continuity? Should NOT be zero and any greater than 8 or 10 ohms is suspect. Someone may be by with the real spec.
zero ohms is a short. Check speaker only, out of circuit.

Is there a fuse somewhere in the tweeter circuit?

Were the speakers plugged or unplugged with the circuit 'hot'? A brief spike can have high amplitude and come and go so quickly you may only hear a brief 'chirp'.

How bad is your singing? just kidding. Mine is worse.

First, thanks for all the responses. I really appreciate them all.

I looked at the crossover circuit board, it looks very clean, no altered color and no smell, I did not see any fuses there.

I am a nobody when it comes to electronic stuff, so I guess, tomorrow I will bring the tweeter to a speaker repair shop to see where the problem is. Hopefully, it is something trivial.

My other alternative is to look for "compatible" 1" diaphragms on line, and try to re-use the Celestion housing but right now I am not sure if that is where it failed.

By the way, I am in Austin, TX, if you know any decent speaker repair shop, please let me know. I just pick it out of random. There are not many of them though.
