Tweeters burned up

[Stefff]

My tweeters burned up after a bad noise like a electric discharge that I heared from the speakers (i suddenly turned off the power amp); the coil and membrane were changed, but the repairman didn't even check the crossover because now the speakers now that have been repaired, are working; it seems strange to me, however, that capacitors, resistors or inductors have not suffered damage ... what do you think? Thanks!!

... what do you think?

I think you should identify the cause and ensure it doesn't happen again 👍

Yes, it was the faulty preamp...

So what was wrong with the amplifier and what make was it, sorry to hear about your speakers

Most crossovers are rated higher than the drive unit which is why the drive units will usually go first.

You don’t mention what speakers they are. Because metallic tweeters are very robust, unless 8 year old fingers start poking in them as happened to me.

Thanks! Among other things, the speakers had just been recapped so the crossover components are almost new

Hallo; soft dome (silk) very old school B&W tweeter...

Years ago speakers were fused iirc, but I think somebody suggested that impaired the sound. Obviously it costs more, but you rarely see it today. (I noticed a fuse yesterday on a Magnepan, but they’re not conventional cones or domes)

Unless they were coated in Unobtanium, of course...
