I did mention several times that the voltage and current are directly
related. That's where the wattage, and the ability to do work, lies.

sure, its all related!
Thats the secret of OHMS LAW that so many folks seem to miss!
And even those that do finally get it that they are all related, they seem
to still missunderstand exactly what the relationships are...

If you had a perfect, zero ohm, superconducting speaker, the current
would be the force,

you mean a DIRECT SHORT! ha ha
Alot of current for a short time till the amp or wires fry themselves...

the voltage would be the speed,

Nope, Kevin!!
Slow down a little!
VOLTAGE IS NOT SPEED!

Electrons flow the same speed no matter if its 9 volts or 12 volts.

A superconducting speaker would be a dead short only if you stopped the
cone. Voltage does determine the speed, just as it does for a DC motor.
The current is (Vin - Vback)/Ohms. The higher the input voltage, the
faster the cone must move to create back EMF to balance the equation.
The amount of back EMF created by motion depends on the winding size.

Of course we're getting theoretical here. 4 or 8 ohms is a lot of
resistance so speakers are far from perfect.

Don't bring electrons into this. They move only a little faster than
grass grows.
