I need help on directionality of speaker cables

The arrow points in the direction of current flow so they should point to the speakers.

Wow, this thread got carried away down the wrong road.

As an EE, the way I see it is that cables with direction arrows on them are solely to get the shield grounded properly. End of story. If they have no shield, there is no good reason for the arrows that I can see.

Skin effect is a function of frequency so DC signals never see it.

What do you think the "signal" is? And don't forget Ohm's Law...

Also, talking about polarity of AC signals is not technically correct. It isn't like DC. AC signals don't have polarity per se, but rather phase angles. The actual direction depends on the relative complex values of the angles. Remember we are talking about voltage and current information for music and not a single sine wave.

Cable makers should just use a sticker or mark on the end of the cable that has shield ground and tell people that the sticker "should" go on the source side. It would cut down on the confusion the arrow causes people, but it would be more complicated to explain, so I guess they chose the easy path.
