Tefag Cornet 1278 horn speaker3D Model
“Tefag” is a marketing abbreviation of the name of the Telephon-Fabrik Berliner AG group, founded in 1898 by Joseph Berliner – an entrepreneur of Jewish origin, brother of Emil Berliner (inventor of the gramophone and gramophone record). From 1927, the headquarters of the company was in Berlin. Due to the Great Depression and the economic, social, and political disturbances in Germany at the break of the 1920s and 1930s, the ownership structure of the company underwent several transformations. Tefag primarily manufactured telephones, cables, and other telecommunication devices, while the production of loudspeakers was a side branch of their operations. Horn speakers consisted of two components. The sound source was an induction/magnetic converter system, as used in telephone receivers. The Cornet 1278 horn speaker was included in the 1928/1929 season.
