Hair??? What hair youze talkin bout???? :-)
While speaker impedance is indeed a moving target, getting the cable Z even down to 20 ohms or so drops the stored energy significantly. In fact, with an 8 ohm nominal load, going from 4 ohm cable Z to 16 ohm Cable Z, the storage only increases about 12%. So the target regime is rather loose..But typical zip runs with 200 nH per foot, they store about an order of magnitude more energy than one that gets within a factor of 2.

Sorry I can't post the graphs of energy vs impedance vs load..not in this forum.
