That works because the transmission line is less than 0.01 wavelength.
So impedance matching becomes moot. If the speaker line were 1/4 wavelength
long, there would be almost no signal transferred at all.


( Unless you use the specially tapered euphonic cable! )


Actually, if you used a thick enough wire, you could go 1/4 wavelength at
audio frequencies. If you connect a speaker straight onto the mains,
chances are you are going further than that from the generator.
