Do you know who also liked to have his face everywhere?
Impedance mismatch between two pieces of equipment (amplifier and speaker, in this case) is a thing, and depending on how the amplifier is built can be a problem. But for the piece of wire connecting them to behave like a transmission line it needs to be a significant fraction of the wavelength of the signal, which at audio frequency is quite a lot, so unless you have your amplifier on the other side of town it is totally irrelevant. The guy was blabbing nonsense. We didn’t talk about quarks.
Resistance can reduce the volume. E.g. if your wires are too thin for the current you want to send over them. The guy was talking about impedance.
Once someone tried to tell me that the wrong cable impedance to the speakers affected sound. Asked him what is the wavelength at audio frequencies, conversation died.
That’s the joke. They would claim that … I don’t know… electrons are going to fall off that copper wire or something like that.

Are you body shaming the satellite dishes?
This joke resonates with me.
