Ledermann relates how Rudy Bozak himself was treated by Bozak's management: "...the new owners of the company relegated him to a dark, unlit corner of the upper floor of the production building near the bundles of stocked cotton wool acoustic stuffing. At the right time of afternoon, when the light streamed in from one of the few windows, you could see the air filled with particulate matter and through it, if you knew where to look, a small, round faced man with felt cap could be usually found sitting in the dark at his old desk with the one small lamp illuminating his face." In 1979, Ledermann designed the Bozak MB80 bookshelf speaker and brought it to the marketplace. This compact loudspeaker contained a soft dome tweeter, a 6" 209-W wide range aluminum driver designed by Ledermann, and a modified first order crossover. The MB-80 employed tweeter clipping protection and indication. Rudy Bozak took note of the project, but did not participate in the design.
