Your speakers drivers are flexy and they operate on shear an compression.
Shear travels from the moving coil and dust cap and both sides of the cone and a polarity of this shear wave is reflected back down the cone corrupting the next wave launch. A fuse contains an element that vibrates with electricity, you can see it in the video posted before it blew..that vibration is never totally mitigated. Transformers vibrate so they will also generate shear and pass it down the line. And so it travels.Tom
^This^ sounds like total, unadulterated (or maybe adulterated) BS.
I do not have a fuse riding on the speaker driver’s cone.
And if I grab the speaker cable like a Pentecostal preacher grabs a snake, it is not pulsating mechanically.
The transformers vibrating would only vibrate a fuse in the holder if the holder was on a flexy piece of metal… But most of the fuse holders are mounted in the chassis and freely floating on the inside.
Even if the fuse holder was flexing, the fuse holder is holding the fuse itself in by using springy clips that maintain contact better than a brush in a motor does.
I do not see how some other stiff fuse would not also have the same mechanical interface concerns, that a certified and UL approved glass cased fuse would have?
But I could be wrong, so Are there some graphs, or links, showing the effect that you are describing?
