In later years JBL chose longer excursion for power, harder to drive than most people think. Efficiency....

With a drawback, had some rather rare 4315 speakers and they confounded for a brief spate till listened and realized when driven by Good SS amps they sounded like a totally different speaker than using ANY tube amps (12 or 13) I owned. The impedance curve must have looked like the Andes mountains.
