Speaker Cable directionality: reversable??

This is a question that has been discussed numerous times on this forum. The answer is yes and no depending who's talking. Since an AC signal is present and electrical energy goes back and forth, you wouldn't think that it would make any difference. There are a few valid engineering
reasons why it is directional depending on the composite of the wire. However, how it effects the sound and to what extent is best found by trying it. I doubt in a blind listening test you would be able to tell the diffrence.

Bob-b---That is exactly why I said there are a "few" engineering reasons why wire is directional. Any electrical or electronics engineer will tell you there is a difference in flow direction (as in a direction) depending on how the wire is made. However, most manufacturers will also tell you to try it both ways and see if you hear a change. Personally, since flow is AC, I'm still a little foggy on why this would be the case since you have flow in one direction on the positive half cycle and flow in the opposite on the negative half cycle. It would be easy to comprehend this if it were a DC current going in one direction. However, it is not. So how can you have directionality? Speaker wire is no different than lamp cord other than composition. In AC circuits, you have a positive and a neutral for less than 120V. Power flows through the speaker coil to the common(neutral) and back through in the opposite direction just like any AC load. Lamp cord under this theory would be directional but I haven't seen any arrows on lamp cords as of yet. Maybe the bulbs would last longer if we got the direction right. I would just like for somebody to explain in plain English why there would be a difference. I do buy into the actual wire being directional to flow but apply this to an AC circuit.

I hope the same amount of power (w = v x a) travels both ways. Phase has nothing to do with power flow. It is simply an orientation to keep both speakers going the same direction or the power flow in the left is moving the same direction with the speaker in the right. I use Tara labs that use separate wires (completely, no common jacket-8 wires for biwiring)) for pos and neg. Both of them have arrows on them. Which one would go where because the power is not going the same direction down both wires and any given time. I personally think on speaker cables that this is a bunch of crap. I will continue to speak out against this until someone can prove how it will make a difference on AC.
