How many electrons?

There is a lot of current between your amp and your speakers. Imagine that you are doing some normal listening to your favorite loud music, and consider the number of electrons that move between the amp output poles and the speaker cables every second, in either direction.

Among the following estimates for the number of such electrons, which one is the most accurate?

a) None
b) Between eighty seven and a thousand
c) Thousands
d) Millions
e) Billions
f) Trillions or more

It's OK to just guess, but if you want to use numbers, the unit of current is an ampere, which is a coulomb per second, and an electron has a charge of about
1.602176487(40)×10−19 coulombs.

With all these electrons it makes sense, IMHO, and an old-school repair guy and confirmed:

Proper design of audio signal should be at line level, NOT passive crossover components in the speaker.

Geese, Wilson et/al charges umpteen million dollars for speakers while missing the whole point. Pity that high-end audio* is so out to lunch, especially for what some charge! Sorry for the rant.
