Speaker cable arrows???

You guys are hilarious. Speaker cable directionality - it IS possible to intentionally design and construct a "directional cable", but not as a passive device. Think about it: does your directional cable possess differing impedance in either direction? If so, how is that accomplished? (hint - it's not).

Then there is the issue of signal to your speakers being AC, not DC as is commonly thought. Again, please explain to me exactly how you can create or maintain directionality in an AC line?

That doesn’t make sense because there are two wires in the AC circuit, not just one. The signal must be traveling down one wire to the speaker while it travels in the opposite direction on the other wire. And vice versa. The signal can’t be traveling opposite to the direction of current and voltage in a wire, can it? That’s why both wires in the cable should be controlled for directionality, such that when the signal is headed to the speaker it’s going in the direction of least resistance.
