There were also control tones on the optical track that fed a controller connected to a bass synthesizer in the booth that fed those speakers. First theater I worked at in 1979 still had the special (Crown or C/V - can't remember) Sensurround amps upstairs and four of the giant horn-loaded woofer arrays in the auditorium (two in the back corners and two under the screen). The bass generator was gone, though.
