In the early 1980s, as an audio salesperson for a Chicago-area A/V retail/custom-install store, I fielded a phone call from Godehard Guenther, the founder and president of a/d/s/. We were one of the largest dealers for their fine line of automotive speakers, and he wanted photos of some of our high-end auto-sound installations featuring a/d/s/. "We don't even have a car-stereo department," I responded, freezing him mute. "We're installing your speakers into the walls of homes." This brilliant former NASA engineer and one-time employee of Wernher von Braun was dumbfounded. Car speakers cut into the walls of houses—what a concept.
