If you put an actual diode in place of a fuse, which orientation would be correct??
Dave.
Follow Ups:
If you put two, half value fuses, in place of the one and put one in one direction and the other the other direction. That should solve the perceived problem. :-)
Also two speakers wires for each one, again one reversed direction from the other. Now you won't need to figure out what the "correct" direction is. You have all the bases covered!!

One of the wires is still incorrect, so having one fuse in the correct direction is the best solution. Duh!
"One of the wires is still incorrect" yes, and......?One of them is correct so doesn't that solve the problem?
One good path paralleled by one poor path equals one better path.
Get it?
.0001 ohm in parallel with 1,000 ohms is something less than .0001 ohm
The value of two parallel resistors = (R1 X R2) / (R1 + R2)

The distortion/noise is produced by any wire in the signal path being in the "wrong direction." Now, in this case you gave the signal would travel the line of least resistance, which is the fuse in the correct direction. So, the other fuse would accomplish nothing. We're back to square one, one fuse in the correct direction. Duh!
"Now, in this case you gave the signal would travel the line of least resistance, which is the fuse in the correct direction."
But the current is changing direction. If fuses (and wires) are directional then each fuse can only be in the correct direction for half of the time. Having two of them , one facing each direction, means you have a good path for both current directions.
I guess you will now tell me that only the current flowing towards the power transformer affects the audio performance of the power transformer. :-)

"Still Working the Problem"
When electrons are moving in the direction of the speaker on the + terminal the moving electric field causes the speaker diaphragm to move OUT. When the electrons on that wire change direction the electrons on the - wire move toward the speaker causing the diaphragm to move IN. Since the direction of electron motion on + wire and - wire is opposite at any instant in time it's obvious that during the time electrons are moving away from the speaker on either the + or - wire they don't affect the movement of the speaker. This logic is the same no matter where the fuse is in the audio path. That's why all cables in the audio system, including power cord and AC power fuse should subscribe to this logic. Same with fuses in speakers if any.So, the only thing that needs to be done to ensure the fuse is in the correct direction is make sure the signal going toward the speaker goes in direction of least resistance which is also the direction of best sound. That can be done at the factory OR at home by fuse in both directions and assessing which way sounds best.
As I already stated current is a scalar, current doesn't move, it has no velocity or direction. Current is a calculation of the total moving charges, I.e., electrons. The electrons barely move, they just wiggle back and forth at high rate of alternation but very low speed. The same electrons actually never leave the wire inside the fuse. Does that surprise you?

"Since the direction of electron motion on + wire and - wire is opposite at any instant in time it's obvious that during the time electrons are moving away from the speaker on either the + or - wire they don't affect the movement of the speaker."
How can you say that?
The movement of the electrons as they approach the speakers voice coil (and as they move in the speaker's voice coil wire) is totally dependent on the wire on the other side of the speaker's voice coil wire.
By the way, if you view the whole circuit as a circle with the speaker and the amplifier at just two points along that circle you will see that the direction in the two wires is really the same direction. The electrons are either moving clockwise around the circle or they are moving counter clockwise around the circle.
sorry, the diagram is not a circle but you get the idea.

What's perhaps more difficult to understand is how a fuse that's located back in the amplifier somewhere can affect the sound since the electrons that are moving in the fuse are not the same ones moving at the voice coil. The electrons in the fuse, way upstream, never get out of the fuse wire. They move too slow and change direction too rapidly. They are "trapped" there.But I'm not trying to solve all the mysteries or conflicts involved with directionality. The best way to proceed I suggest is try reversing a fuse yourself, or speaker cables, and see if you hear a difference. Which is in fact what most audiophile fuse manufacturers suggest anyway. Most if not cable manufacturers like AudioQuest who control their cables for directionality mark their cables with arrows pointing in the direction of the speakers. Not to be confused with cables that use arrows to account for shield direction. As I said, most skeptics would rather fight than switch. What are they afraid of? Wire and fuse directionality is repeatable, transferrable, predictable. Where's the beef?

"What are they afraid of?"Not a thing. I am an engineer type and I always look for the "why" in things.
Do you find something troublesome in that?

Do you see why wire in AC circuits is directional? That's really the primary question of this thread. The secondary question is why you haven't experimented with fuse or cable directionality. That was the gist of my remark.
Edits: 05/22/23
I can see that wire could be directional to a point but turning it around solves nothing in a AC circuit.
"....you haven't experimented with fuse or cable directionality."
Who said I haven't?

If you have experimented you didn't do it carefully enough.
I could sneak into your house at night and change the direction of your speakers wires and fuses and you would never know/hear the difference.Tre'

remember, his reference system is a sony walkman
A backsliding pseudo intellectual to the rescue.
I suggested that and got blasted.
Too much is never enough
And you're still alive to talk about it.
I felt the bullet whiz past my ear. It was s close thing.
Too much is never enough
Yeah, nice!
That way a tweaker-audiophile has to buy twice the amount of expensive fuses. :)
And, the subjective evaluation process for determining proper direction(s) just got a whole lot more complicated. :)

A diode would only allow the current to flow in one direction.

Yeah, I know the answer to the question.
I was asking pictureguy. :)
Dave.
Not In place of a fuse..with....oriented so the current flows only in the 'best' direction.....have the wire also oriented that way.
Same thing going the other way...
