Speaker Cable directionality: reversable??


I bought a demo pair of XLO ultra 6 cables which have directional arrows on the ends of them. The specifics of my equipment requires that I would either have to re-terminate them (to take the spades off the amp end) or else hook them up in reverse of the labelled arrows.
Is there any reason why the cable direction matters, or would reversing them just mean I would have to "break-in" the cables again.
Please help me out; I don't want to undermine the quality I paid good money for!

Much thanks for any advice!!

Okay, I'll take a stab at it. If the wire is drawn thru the die in such a way as to align the molecules so that electicity flows better in one direction than the other, as Bob B. so eloquently point out, then it has a "phasing" orientation, just like a speaker does. A speaker operates on AC, but it is clearly marked + and - for phasing. Perhaps the wire is molecularly oriented to better carry the signal in the "drive" direction, and less oriented to go in the "reverse" direction. This could have some effect on "back EMF" generated into the amp, by the drivers, because the + terminal is connected to the amp's output device, and the - terminal is connected to ground. And it could also have some effect on the perceived "speed" of the cable on transient response.

How does that sound for a theory?
Put on Beatles record. If you hear 'Paul is dead', your wires are reversed.:)

what is the theory about which way the wire was drawn anyway, does the wire become like a diode?

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.
Oleander: Just turn your wires around and don't worry about the arrows. It won't make a whit of difference. (It can't: The signal flows in both directions.)
Oleander .. sorry for the misunderstanding ... you can get banana-spade adaptors, as other posters said.
You seem to have replied without reading my post .. if you hook them up the wrong way around won't you always be a bit curious as to whether it would sound better the "correct" way ? Won't you end up switching them around eventually, just to see(hear)? I think you will since you started this thread, so it shows that you're concerned about it, and I doubt advice on this thread will completely put your mind to ease.
So my advise was to put them the right way around now, whatever it takes, or else it will just play on your mind that "perhaps the sound could be better".

I don't think it will make any difference, but does my opinion really convince you to the point where you don't need to try it for yourself ?
