No it's a total myth, electrical signals that transmit sound are AC, the electrical energy moves "backwards and forwards" making your speaker cones move, in and out, backwards and forwards, using alternating electrical energy that is bidirectional through a wire.
It's as ridiculous as claiming special directional cable needs to be used in your house wiring for your appliances. It's AC.
What is" intriguing" is that people are allowed to advertise this misinformation to take advantage of poor people who believe it.
You can swap polarities of your wires around putting speakers out of phase with each other. Red on speaker go to red on your amp and black to black. That's all.
Apart from that, it's all a fiction to "steal" your hard earned cash.
