No one actually knows how to lculate what speaker cable they need

It goes back to cable manufaturars, mostly provide no relevant data! to sales and the users. None will answer this!
Whay do you think that you own now the optimal cable to your setup?
I think I've figured it out. 

Google it up. I never thought it matters, after all, we use it, on daily bases, in every electric device on the planet. For some reason, audiophiles tend to think that it is special in their sound system. Well it’s the same. Many of those are life saving equipment, military, space, measurement devices, cellphones and more. None ever tend to go, where audiophiles go: BS land.
Not interested in Googling.
I want to know YOUR theory on how electrons flow through the conductor.
Mr.  eichlerera
Sorry to disappoint you, but I don't have a theory of MY OWN, on electrons flow through the conductor. I learned it as all other from the very basics on conductivity. 
It served me well, on all circuitry I designed, built and tested. 
This reads like kenjit created a new on-line persona to bring his unique perspective on speakers to speaker cables. Clever. What next? Amplifiers? DACs? So many targets for a guy with an obsession to feed and no discernible listening skills, leaving only one way it can go. Blather on, dude. Blather on.
Sorry, I have no idea of what you are talking about. You must be mistaken me with someone else.
