  • Notes
  • Amperion Flat Wall Speaker
    This is one of the possible loudspeakers for the "Mystery Music" model 2 and model 2 1/2, which are a record changing mechanism, with pick-up and amplifier, supplied in a compact cabinet to be installed out of sight. See details and more pictures by clicking the links.

    At the same time different speakers were introduced, like a model for corner placement, a console speaker, one for a flat wall and one without cabinet for concealed installations. According to Robert W. Baumbach, these cheaper Amperion instruments were introduced in March 1930.
