The tweeter on my speaker has a crater...Help

Sorry for the long post, but I hope somebody can help:
I noticed today when I took the grills off from my Monitor Audio Silver 6 speakers, that the tweeter on the one on the right has a large crater, as if it's been pushed in by someone. Now I can't tell if my kids could have banged against it by accident. They are young but very mindful of my audio equipment.
So could it be something else that could have caused the tweeter to distort out of shape? I remember one thing probably about 6 weeks or so ago, listening to a Miles album, that it sounded quite horrible and the trumpet was screeching in my ears. After a few minutes I couldn't pretend to be enjoying myself and had to turn it off. I got busy and didn't think about it any more about it at that time. But today after I found out the problem, just out of curiosity I listend to a Dave Brubeck SACD, and I couldn't tell if anything was wrong (but then I am not very experienced on the listening side of things).

So anyone have any ideas what could cause something like that to happen? And what kind of problems warranty will cover? Money is pretty tight right now so this is very disappointing if warranty does not cover it. I listen at moderate levels, nothing very loud at all. I have the Rotel 1060 amp and the RCD-961 CD player and the Phillips 963SA dvd/sacd player.

Thanks for any help.

Take a peice of tape and gentle try to pull out the indent. Masking tape is best. If you really feel brave, use a straight pin. Just barely prick the surface, but don't poke a hole through it, and gentle pull out the dent. I have used both techniques in the past on customers speakers that their kids have abused.

Good luck,

Hey, you could also try a low power vac. to suck it out.

Take your vacuum and hook up the hose attachement. Turn it on and very carefully approach your tweeter with the hose. Do Not Get Too Close! The vac will pull the crater out of a soft dome easily, a metal dome may be tougher...

Peak's suggestion worked with mine. Had similar problem, and covering my tweeter with a smooth soft cotton cloth, I used my vacuum and it worked!
Just be careful..

Yes, it has been pushed in. It covers about 35-40% of the tweeter dome. Well, I will see what my dealer says then I will try one of the suggestions.

What I don't understand is why I didn't hear any discrepancies in the sound. If the tweeter dome is out of shape, should it not affect the sound? And can an overload cause this kind of damage?

Thanks,
