Arh, I remember all sort of speaker problem ages ago. Never got around to figure what was wrong. I suppose this is it.

But does anyone have list of Manufacture that does provide speaker with BIOS Protection?. Does Apple do?

How would that work? Just detect signals with an abnormally high RMS and block them?

With a compressor or limiter. These are solved problems in both analog and digital signal processing.
