Are my monitors blown?

[Fifth Paradox]

Hi guys.

Recently I invested in a pair of KRK RP6's. Everything was going great with them, they were a huge step up from my old fostex monitors.

However the other day I was working on some stuff where my sub bass peaked pretty high in logic. I got a kind of distorted sound and a kind of plastic/rubbery smell out of the bottom vents.

Now I'm not sure if I am being paranoid over worrying about the speakers but to me the left monitor sounds pretty crap compared to the right one now.

Also, there is a pop/click kind of sound when I turn the left one off, and when I turn it on the cone moves in and out slightly.

This doesn't happen with the right speaker, so I'm moving towards there being a problem with the left one.

So my question is, based on what I have explained has one, or possibly both speakers been damaged?

I'm using XLR to TRS connectors, my dB setting on each speaker is 0dB and HF setting is -1dB.

I have only had them about a month, so they are still under warrenty.

Cheers!

If they are under warranty still take them to the shop.
Theyll tell you if theyre blown/damaged or not

I bought them from an online distributor, and I'm already having trouble with this company over another product they sold me which has broken within warranty.

I've had advice from a few friends anyway that have suggested the diaphragms may have gone, so I will have to attempt to send them back for repair or replacement I guess.
