Speaker cable arrows???

Jea48? Thank you! 
The thread you referenced earlier was absolutely on point!
 Herman and Kijanki both expound precisely with "correct" information to help explain doubts about this subject matter. And further they accomplish this in a way that I think most here can understand.
 Nsgarch, Almarg and also yourself, also add to this nicely rounded thread. 
 I would highly recommend that anyone here with any doubt or question on this subject? Please reference that thread before continuing here on this one;

Um, That just looks wrong, 
What I meant, 
Please read the thread referenced by "Jea48" in the hypertext above. 
That is, before continuing here if you have any questions or doubt's about this subject.; "Directional audio cables".

While there is good information in that thread, maybe a few posts, most of it is a disaster, and pretty much none of it matters at audio bandwidths. Transmission line effects are not relevant at audio bandwidths and cable lengths except poorly matched digital cables and connections. Bulk effects would be far more relevant and there would need to be directional differences large enough to make a difference. There are many reasons cables can be directional and that thread only covers one really, but huuuge difference between reasons and MFG differences large enough to have any potential ability to be audible.

Unbelievable!
Think “electrons”, “magnetism “...
The arrows should be pointing North. 

Install them in whichever direction they sound best to you. Personally, I always start by following the arrows on the jacket, but having violated that many times, and in the majority of those cases without any noticeable difference, it's not something to be obsessive about in my opinion, but you know what they say about opinions, they are like rear ends, everybody's got one.
