The Edison Amberolas were Edison's attempt to provide competition for the
Victrolas being introduced by the Victor company. These were
the first Edison phonographs to make use of a concealed horn.
No longer did the house wife have to dust or work around the horn which always
seemed to be in the way! The price of $200 for the Amberola I-A, the
first Amberola, was much higher than the outside horn phonographs of
the day. Soon Edison introduced Amberolas that were lower in
price. These led to the demise of outside horn cylinder phonographs.
