Visonik brand history:

Formerly part of Heco Hennel und Co GmbH, Schmitten, the Berlin branch became independent after the sale of the West German parent company to the Rank Organisation around 1974 with the brand name Visonik as Heco Hennel & Co KG, which was distributed by Hamburg-based Dahl Elektronik. In 1975, Visonik launched the DAVID small hi-fi box on the market with great success, and the range was then expanded by 3 larger compact speakers of the DAVID series, among other things. After Dahl AG's liquidity problems, the Berlin plant suffered a follow-up bankruptcy in 1979 and was taken over by Bruhns AG, which continued the hi-fi loudspeaker business for several years. Around the mid-1980s, the constantly declining production was discontinued and the brand name was sold.
