From Alan at Axiom's audio tips.
"The voice coil of the woofer (the bass driver) contains more than 100 feet of fairly thin wire, much thinner than your speaker cables. It’s that thin wire in the woofer voice coil plus the wire in the tweeter’s voice coil (probably 20 feet or so) and the wires in the crossover that comprise the speaker’s impedance."

A computer once beat me at chess, but it was no match for me at kick boxing.
