The guru on fuses:

Jesus Tom, you had me waste half an hour reading all this bending wave speaker stuff only to learn at the very end this borderline magical technology is 86dB at 2.8 ohms. In other words, useless.

Oh well, at least I learned something. Unlike these other boobs you are wasting your time with here. They never learn anything. Why do you bother? All the cool stuff you're talking about, right over their heads. Oblivious as Drax. https://www.youtube.com/watch?v=iLttd33j-GQ
They are not worth your time. Not even.

Someone directed me here. So I just wasted the last five minutes on this drivel. The one entertaining bit, the "don't care" kids who all hear the difference so easily they can only think anyone who can't is like grandma, they can only hear you when you shout in their ear.

Only in this case they not only can't but won't hear. And their heads are so thick nothing ever gets in that way either.  

This all makes perfect sense in light of which ones here are playing the part of grandma. Can't hear. Can't think. Pretty much potato waiting for the reaper.  

What I don't get is Tom why are you wasting your time with these losers? Surely you have better things to do. I sure do.

Bye!

Always amazed how different people are able to see or read the same thing and come to completely different conclusions. Here's what caught my eye: 

Of course, this is almost impossible to measure statically. Once you put a resistive load on and a certain amount of power the fuse is going to go up to it’s temperature and stay there and the resistance is not going to change very quickly, so you never know that the fuse is distorting. It only distorts getting up there and then going back down. It doesn’t necessarily distort by the time you’re ready to make the measurements. That’s one of our problems with static measurements. You just don’t know everything that you need to know.

Something I have been saying for a very long time now: measurement ain't all that!

Also this one passage, the lower half of page 6 that OP thought was so good, all it talks about is resistance. 

It's also a really, really simplistic view. After all, he himself says

The resistance invariably rises as the temperature goes up --that’s pretty much the laws of physics

Something you learn in entry level classes, by the way. 

So put it all together, what have we got? The man himself saying it should be obvious there's a lot more going on than we can measure.

Well if we can't measure- and no less an authority than John Curl just told us we can't- then what are we left with? Our ears. Listen.

When we do that it very quickly becomes perfectly obvious there are vast differences between fuses, and even between the same fuse used one direction vs another.  

Go and listen. You will see.
