Definitive Technology

Lore & Background

Definitive Technology was founded in Owings Mills, Maryland, in 1990 by Sandy Gross, who had previously co-founded Polk Audio, along with Don Givogue and Ed Blaise. The company's initial offerings were monolithic bipolar speaker towers. In 2004, the company was acquired by Directed Electronics, a company founded by Congressman Darrell Issa that specialized in car alarms and radar detectors. Following the acquisition, Sandy Gross became President of the company's newly formed audio division. Directed Electronics also bought Polk Audio, which Sandy Gross had co-founded. In 2008, Directed Electronics restructured itself as DEI Holdings. In April 2013, the company combined Polk, Definitive Technology and the Boom Movement brands into a new division called Sound United. In April 2015, the company released its W7 speaker with support for the Play-Fi wireless protocol for multi-room audio, produced by audio company DTS, Inc., now owned by holding company Xperi. In May of the same year, Sound United's parent announced a deal with Austrian electronics company Aqipa to distribute Definitive Technology and other Sound United brands in Germany, Austria and Switzerland. After Sandy Gross left the company, he introduced a third company called Golden Ear Technology in 2010, which is completely separate from Sound United and DEI.

Reader's Guide

Definitive Technology's significance lies in its lineage from Polk Audio founder Sandy Gross and its evolution from a Maryland startup to a California-based unit within the Sound United division of DEI Holdings. The company's early focus on monolithic bipolar speaker towers established its reputation in home audio, and its later expansion into soundbars and headphones broadened its market. The acquisition by Directed Electronics in 2004 and subsequent integration into Sound United alongside Polk Audio and the Boom Movement brands reflect a consolidation of audio brands under a single corporate umbrella. The release of the W7 speaker in 2015 with Play-Fi wireless protocol support marked the company's entry into multi-room wireless audio, leveraging technology from DTS, Inc. (now owned by Xperi). The distribution deal with Aqipa extended its reach into German-speaking European markets. The company's legacy is tied to its founder's repeated ventures in audio—Gross co-founded Polk Audio, then Definitive Technology, and later Golden Ear Technology—illustrating a pattern of entrepreneurial innovation in the speaker industry. Definitive Technology remains a recognized name in home theater and wireless audio, though it operates as part of a larger corporate structure.
