Problem with PMC PRODIGY 1

[rayolight]

Purchased the Prodigy 1 speakers in February of this year. They have been excellent, doing everything that I wanted them to do ,great soundstage, excellent bass and super mids and highs,so all good.
Switched my system off the other night after about a 3 hour session all fine.
Switched the system on next evening sound sounded flat with no highs,on checking,both tweeters were providing no sound. Visual check and as I hope you can see from enclosed pictures,absolutely no damage . I have 2 amp systems so tried them on other system with exactly the same results . Contacted PMC but they just referred me to distributor as on warranty. My question is has anyone else had any problems with these speakers, I am sure I will get comments that they have been overdriven, can only say not as far as I am aware,smallish room so no need for power. I believe some speakers are fitted with fuses is this a possibility.Can a tweeter be blown without any damage to the cone ,bearing in mind this has happened to both speakers. Due to my location in Spain sending speakers back for repair is a nightmare and if I could confirm what caused the problem would be happy to buy 2 replacements when over in UK for Christmas. Has anyone replaced one of these tweeters, is it easy, looking forward to any constructive comments
Thanks

Drivers can sometimes just fail, but it'd be extremely unusual for both tweeters to just stop working.

I know that the obvious reason would be that they were overdriven, but they were working fine until I switched them off. Just trying to workout if it's possible that the crossover failed. Is there some safety fuse fitted which failed when system switched on,I know it's highly unlikely, it would happen to both but it has,and no visible signs to cones,I'm perplexed .I would just like to understand what has happened, if I have to pay for new parts,that's fine😟

You're really not very lucky with speakers are you Ray?

What were you using until they failed?
Was it flat,with no boosted treble and well within its comfort zone (and sounding like it)?
