History

The company that became Sound United was founded by future US Representative Darrell Issa and his wife Kathy in 1982 as Directed Electronics, with Darrell Issa serving as the first CEO. In 2000, Darrell Issa was elected to the House of Representatives, and Jim Minarik replaced him as CEO.

In 2004, the firm bought speaker company Definitive Technology; in 2006, it bought Polk Audio.

In 2008, the companies adapted a holding company strategy, and their parent became DEI Holdings, Inc.

In 2011, the company was bought by private equity firm Charlesbank Capital Partners.

In April 2013, the company combined Polk, Definitive Technology and the Boom Movement brands into a new division called Sound United.

In August 2016, Kevin Duffy was named the company's CEO, replacing retiring CEO Jim Minarik.

In March 2017, Sound United acquired YS consumer electronics company D+M Group, whose brands included Denon, HEOS by Denon, Marantz and Boston Acoustics. At the time, D+M was the world's largest supplier of audio/video receivers.

In October 2020, Sound United acquired Bowers & Wilkins.
