The Kalamazoo Duplex
SEE ALSO: Our listings of outside horn talking machines for sale.
Manufactured around 1906-1909 in Kalamazoo, Michigan by the Duplex phonograph company, this unusual twin-horned machine was advertised in popular periodicals and sold by mail order. The design of the motor suggests that motor production was sublet to Columbia, although the motor does not swap with any Columbia disc machine models. Litigation initiated by the Victor Talking Company forced the Duplex out of business. Although the dual horns did not represent a significant technological breakthrough, the odd looks of the Kalamazoo Duplex have always made it a collector's favorite.
