AlNiCo power handling?

[Psycho Bass Guy]

Just driving AlNiCo speakers hard causes them to degauss some. It won't totally demagnetize them, but they won't perform to their original spec. I understand theaters had regular yearly maintenance of sending out drivers for regaussing.

This is far from true. Matter of fact, among common speaker magnet materials, AlNiCo is one of the LEAST susceptible to heat degaussing.

As for the rest of your post about annual remagging requirements, it is purely fantasy.

I use two 150 watt AlNiCo JBLs with my 300 watt Eden VT300. Although the amp can produce a huge amount of peak power, I'm not worried about the speakers.

I've never seen an AlNiCo magnet speaker that advertises handling 250 watts.
