Konski & Krüger was founded shortly after World War I and specialized in the development and production of electrical and electro-acoustic components. In the 1920s and 1930s, their most renowned products were speakers, sold under the brand name "MEMBRA", derived from the word "membrane."
By the late 1930s, the company had grown to 135 employees and had expanded into manufacturing high-quality sound systems for cinemas, which were experiencing a surge in popularity. Around the same time, they also began licensed production of the Enigma cipher machine, which was widely used during the next war. Approximately 40,000 units were produced.
The exhibit features a simple and affordable model of an external speaker, designed for connection to standalone radios or electric gramophones, embodying the brand’s legacy in audio technology.
