no i think speaker efficiency would just be sound pressure vs. watts.
power factor is like phase angle i think you could say....
if you measure the power factor its a percentage of efficiency of the energy generator in the powered circuit. so if a set of cables is better than another it should raise the power factor maybe?
power factor is drawn as a triangle. watts on one side, var's on the other.
solve for hypotenuse and divide answer into watts. answer is power factor.
counter EMF from the driver against the amp and how it is affects the phase is what we are talking about here i guess. certainly there is more than impedance shown to an amp from a driver. and it's level driven.
check wiki for an explanation of VAR's if your interested in this. hard to explain here.
