Subscriber loudspeaker `` Leningrad ''.
Subscriber loudspeakers.DomesticSince 1949, the subscriber loudspeaker "Leningrad" has been producing the Leningrad Plant of Radio Products No. 3. "Leningrad" is a standard subscriber loudspeaker. Of the features of the AG - this is initially a colorful fabric on a loudspeaker, instead of radio fabric as in the main photo, which I did in Photoshop, replacing, as it seemed to me, someone inserted colored fabric on a radio fabric, it turned out I was wrong. The subscriber loudspeaker is designed for a 30 or 15 V radio broadcast network. The range of reproducible frequencies is 200 ... 6000 Hz. Volume control is carried out by switching the taps of the input transformer.
