In 1984, Joseph J. Sahyoun, a music freak and Aerospace Engineer unhappy with the existing loud speaker technology and performance, decided to put his advanced knowledge in aerospace technology to use.  He pushed his technological boundaries to the limit to create the kind of subwoofer he could live with. 

Earthquake's innovative audio technologies connect millions of people around the world with the sound solutions they need.  EQ Sound designs, manufactures, and markets high performance audio systems for use in home and audio-video systems, and after-market and OEM automotive systems.
