Voice of the Theatre speaker systems  (1945 - ?)
Altec-Lansing


Legacy A7 Voice of the Theatre


Range of classic two-way speaker systems, originally designed for cinema sound, later becoming popular for general live reinforcement. The design was  the result of a collaboration between John Hilliard and Jim Lansing (who went on to leave Altec-Lansing and form JBL (his initials)). 
The efficiency of the designs provided high sound pressure levels from the limited amplifier power available at the time.
