At the club, Long used four Levan bass horns, one in each corner of the dancefloor, to create a "haptic and tactile quality" in the sub-bass that you could feel in your body. To overcome the lack of sub-bass frequencies on 1970s disco records (sub-bass frequencies below 60 Hz were removed during mastering), Long added a DBX 100 "Boom Box" subharmonic pitch generator into his system to synthesize 25 Hz to 50 Hz sub-bass from the 50 to 100 Hz bass on the records.

. Initially installed in 17 U.S. theaters, the Cerwin Vega "Sensurround" system used large subwoofers which were driven by racks of 500 watt amplifiers which were triggered by control tones printed on one of the audio tracks on the film. Four of the subwoofers were positioned in front of the audience under (or behind) the film screen and two more were placed together at the rear of the audience on a platform. Powerful noise energy and loud rumbling in the range of 17 Hz to 120 Hz was generated at the level of 110–120 decibels of

By 1976 there were almost 300 Sensurround systems leapfrogging through select theaters. Other films to use the effect include the WW II naval battle epic ''Midway'' in 1976 and ''Rollercoaster'' in 1977.
