Not yet having read your article (tomorrow morning hopefully), I would then pose the question: since loudspeakers vary enormously in design and manufacture, then might it mean that a fuse which might work “well” for one amplifier/speaker combo might not work for another combo (maybe even the same amp and a different speaker)?

That doesn't work, either. Maybe they fell foul of UK Trading Standards and won't send their web pages to UK addresses. Like many of these fairy tales, there is a grain of truth. If you put a carefully-chosen fuse in series with a loudspeaker, you can measure intermodulation distortion in the voice-coil current due to the element changing its resistance with temperature.

Link doesn't work for me. I'm devastated.

(The specs don’t indicate whether the fuses and power cords are certified.)
