OBSESSION IN SOUND
Def Tech as they are fondly named in the USA are a relatively new manufacturer to the European and UK markets. They are well known for their high end Home Cinema loudspeaker systems and are a highly regarded manufacture that is technology driven.
The company was founded in Owings Mills, Maryland in 1990 by former Polk Audio founder Sandy Gross, along with Don Givogue and Ed Blaise. Gross served as the company's first CEO and President. The company's first products were monolithic bipolar speaker towers. In April 2013, the company was combined with Polk and the Boom Movement brands into Sound United, who also own Marantz, Denon and Classe Audio.
