Before
Franklin M. Doolittle formed the Doolittle Radio Corporation and
applied for a license for radio station WPAJ in New Haven,
his company manufactured various types of radio equipment in the
early 1920s.
The
Amplifone was a loudspeaker that could be attached to a radio receiver.
It was later altered and advertised as the Audimax
in 1922.
