I am experimenting with DIY speaker cable and have a question. How do you make speaker cable directional? And does it make any difference? Please advice.

cables have no direction.

Correct me if I am wrong, for IC, if you connect the shield to the ground, the IC becomes directional. Does this also apply to speaker wires?

how about some diodes?

diodes only allow current to flow in one direction i.e. "forward bias"

Cables can be directional in that their outer shielding is connected to the ground terminal at only one end, which should then be connected to the source rather than the destination to avoid the transmission of electrical interference.

This is irrelevant in speaker and headphone cabling as there is no shielding necessary - there are no active electronics stages at the destination, so there is nothing that can possibly pick up electrical interference

On top of what TheSloth said about a lack of amplification, speaker cables typically have an 8ohm impednace. Interferance rises with load impednace which makes amps much more suseptable (I don't use shielding though and don't have a problem).

Don't buy into manufacturer's crap that cables are directional because of the way the cable is drawn from the melted copper or silver or similar BS. Audio signal is AC so even if a cable were directional in some twisted sense due to this plugging it in backwards would have no audible effect at all.

Thanks for the info folks. I am not going to worry about it then.

if the music has no DC offset, diode will behave like a rectifier.

A rectifier is generally made from diodes.

That's my point, your post implied of using diode in cable to make it directional.

If I take your words wrong, I apologize.
