More about the Altec Lansing Voice of the Theater:
Altec Lansing made the Voice of the Theatre systems. The design resulted from a collaboration between John Hilliard and Jim Lansing. Douglas Shearer didn't hesitate to approve the Hilliard's proposal and authorized "any reasonable budget". Hilliard became the team leader of this new project. Hilliard immediately recruited Lansing Manufacturing, Robert Stephens, a design draftsman on MGM's staff, and Harry Kimball. The speaker was named the Shearer horn. Later on, a more refined model, the VOTT, was introduced. The smallest model, the A-7, used a medium-sized sectoral metal horn for high frequencies, which featured dividers (sectors) to provide control sound dispersion, plus a medium-sized wooden low-frequency enclosure, which functioned as a hybrid bass-horn/bass-reflex enclosure.
The most often used Voice of the Theatre system was the A-4, many of which are still in use in motion picture theaters as of 2018 The efficiency of all of these products originally provided high sound pressure levels from the limited amplifier power available at the time. The original Voice of the Theatre series included the A-1, A-2, A-4, and the A-5. The A-7 and A-8 were designed for smaller venues.
Bill Hanley used Altec high frequency drivers and horns along with JBL bass drivers in his custom-built loudspeaker system for the Woodstock Festival in 1969 Some professional Altec Lansing products remained in use well into the 1990s.
