So, let's see how this plays out for a 10 foot speaker cable made of 16 awg, 2 conductor lamp cord. Assume we have an 8 Ohm speaker which actually has an 8 Ohm impedance at 20k Hz. More realistically, a typical 8 Ohm speaker system will have an impedance more like 10 Ohms at 20kHz due to the voice coil inductance. This further reduces the effect of cable inductance. Someone could look it up but I bet it is more like 1dB or greater. Now, assuming these more realistic numbers, let's ask how far we could run a " lamp cord" before it had enough level loss at 20kHz to have even the slightest chance of being audible by someone with excellent hearing at this frequency extreme.
Breaking the problem into parts, let's first see what series impedance is required to give 1 dB attenuation. For a 10 Ohm load I calculate that 1. Now, what inductance results in 1.
