Inside Cabinet Speaker Cable Causing A Big Difference in Sound

[planet10]

Cable threads have almost universally ended in ruin

Last 3 posts are already taking us in that directions :^(

So trying to stop a trainwreck or even calling it so is a ruin?

What would you call the trainwreck itself?

Just curious.

I said heading…

Let him experiment and gain experience.

Will do more research and experiment a bit.

I am using 1.25sq single core coaxial cable (TPC) inside.
The shield wire is a single point ground on the cold side.

I think you should try it and choose the cable you like.

Cable threads have almost universally ended in ruin, we do not encourage them.

But...but...it's 1/3 of the system! And there may be something to that cryogenic processing.

Oh well, at least the ruins would be gathered together in one place, for easier maintenance.

OK, here's a possible scientific reason why replacing the old copper wire inside the speaker enclosure could have made a difference.

Copper is not magnetic in normal conditions, but becomes weakly magnetic in the presence of a magnetic field, such as that found within a loudspeaker enclosure.

This weak magnetic effect is a consequence of copper being a diamagnetic material: https://en.wikipedia.org/wiki/Diamagnetism

The replacement internal wiring may not immediately acquire this magnetism, and that may account for the audible difference that has been reported.

Discuss! 🤔

The OP should also check his solder work. 12g is kinda gard to solder.

But bad soldering would give different issues not like this one.

 

[Chompy]

Where are the measurements?

 

[NareshBrd]

Agree, use proper soldering technique, but OP claims improvement!
So maybe the original soldering was bad?
Or the wire is of a different type, twisted or shielded?
Or the shield was connected / disconnected from amp or ground?

But like JMF says, more a perception bias...my opinion at least.

 

[planet10]

They original change that caused improvement was amplifier to loudspeaker, doubt there is a solder involved.

What is the terminal diameter for Markaudio Drivers? It doesnt say on the datasheet tho 🙂

 

[planet10]

Terminal diameter?

dave

 

[Kitarist]

So instead of soldering would just put terminals on there

 

[planet10]

I always solder. But i typically use 24g solid wire.

MA drivers (at least the Altair’s) come with quick connect terminal bits.

dave

 

[Kitarist]

Yes but what is the size of them? There are few different sizes

 

[planet10]

They are special and come with the drivers. 2 sizes. Big and smaller.

dave

 

[Kitarist]

Yea there is nothin on datasheet so seems will have to measure

 

[nandappe]

The connect terminal is 50φ for installation.
The terminal width of Pluvia7HD is 4.5 mm.

Round & faston terminals are soldered after crimping.
I do not solder directly because I connect and disconnect many drivers.
