Subharmonic synthesizers can be used in professional audio applications as bass enhancement devices during the playback of recorded music.
A subharmonic synthesizer can be used to extend low frequency response due to bandwidth limitations of telephone systems.
A subharmonic synthesizer (or "synth" as it is known in the industry) creates a bigger presence and can give the music that much sought-after "punch".
A key approach used by engineers to get heavier, deeper bass sound was to add huge subwoofer cabinets to reproduce the sub-bass frequencies.
The Paradise Garage discotheque in New York City, which operated from 1977 to 1987, had "custom designed 'sub-bass' speakers" developed by Alex Rosner's disciple, sound engineer Richard ("Dick") Long[1] that were called "Levan Horns" (in honor of resident DJ Larry Levan).
