Disco
Sound and light equipment

Powerful, bass-heavy, hi-fi sound systems were viewed as a key part of the disco club experience. " Mancuso introduced the technologies of tweeter arrays (clusters of small loudspeakers, which emit high-end frequencies, positioned above the floor) and bass reinforcements (additional sets of subwoofers positioned at ground level) at the start of the 1970s to boost the treble and bass at opportune moments, and by the end of the decade sound engineers such as Richard Long had multiplied the effects of these innovations in venues such as the Garage."

Typical lighting designs for disco dance floors include multi-colored lights that swirl around or flash to the beat, strobe lights, an illuminated dance floor, and a mirror ball.
