Between 1906 and 1918, the Victor Talking Machine Company produced a most intriguing machine called an Auxetophone. It was an external-horn phonograph mounted on a beautiful cabinet, but it wasn't a purely decorative or aesthetic choice: the cabinet doors concealed an air-compression system that was connected to the soundbox and amplified the records *way* beyond the capabilities of an ordinary external-horn model or a Victrola. Some of the volume was necessary to lessen the noise of the compressor and these machines were clearly better-suited for public spaces than homes (without the compressor, Auxetophones produced a rather weak tone. However, they could be fitted with a standard soundbox and function like any other external-horn Victor). They are quite rare today, but a few collectors are lucky enough to own one.
