I have yet to seen a picture of a thermally damaged VC on these forums. Every single one has been a mechanical failure.
I've been saying the same thing for a while now. The only person I've heard from who has supposedly fried a VC in a home setting is Chuck, and that was a DVC. Well now folks understand the real deal about the VCs on these modern drivers and that they are quite hard to fry.

There is an old test made by Richard Clark where he tested an AA Brahma and a JL Audio 13W7. They both could take 32 kW at 80 Hz when using burst signal.

The peak spec for the LMS-5400 is 8000 watts, but I'm guessing that's way way underrated. It should be able to take 40-50 kW (above ~65-70 Hz) or more in a small sealed enclosure when using burst signal (when distortion is not limited naturally).
