Altec Lansing also 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.
