As the era of the player piano came to an end, Hupfeld also sought to participate in the rapidly expanding market for large-scale radio and recorded-music sound systems. To this end, the company introduced a range of loudspeakers marketed under the brand name "Atlantic". This small brochure describes the various Atlantic loudspeaker models and also includes a price list. It provides an interesting insight into Hupfeld's efforts to diversify its product range during the transition from mechanical music to modern sound reproduction technology. We offer a PDF copy of this rare 3-page brochure for research and study purposes at a price of EUR 15.00.
