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.

I remember sitting more toward the back of the house and hearing the rear Sensurround speakers roaring to life when appropriate. They were located in a back corner, and recall they may have removed some seats to fit them. Working with live sound later in life, I used some horn loaded CV's with 18" woofers that reminded me of those Sensurround speakers.

I wonder why the British 101 films label announced a new bluray for this movie, since there is already a UK release.
maybe they'll add an extra or something?
