I was reading a thread about a new speaker protection device that could be installed in a speaker.
It was not your standard light bulb or resistor , polyswitch type device.
There was a link to youtube videos as well. I watched one where they were feeding I believe a 4 inch speaker with a bridged power amp at 4000 watts.
Not 100% sure where I was reading this but wanted to watch the rest of the videos but lost the link.

Anyone remember seeing this and can point me in the right direction?

Thanks for any help;
