The first electrostatic speaker available on the German market, the LE 1 provided a new housing for innards produced by English engineering company Quad, then trading as Acoustical Manufacturing Co. Ltd. The LE 1’s electronics were based on the Quad ESL-57, producing a distinctively detailed sound that still stands up well against the standards of contemporary hi-fi. At the time of its introduction, the speaker was technically and aesthetically ground-breaking. Within the Braun audio program of the late ‘50s, the LE 1 was intended to accompany the first Braun Hi-Fi system, studio 2.
