B&K was founded in 1981 and is based entirely in the USA. B&K started as an affordable high-end audio product producer similar to Adcom, and effortlessly evolved into home theater and multi-room categories to emerge as a market leader in the late 1990s.

B&K makes multi-room amps and preamps, powerful 2-channel gear, and whole-home audio accessories like in-wall control pads and jacks.

In late 2010, Amplifier Technologies Incorporated (ATI) has acquired B&K with the intention of continuing the brand.

Notable products include the B&K AV 100.2 Class D amplifier, the B&K Reference 200.5 200-wattx5 home theater amp, and the B&K AVR707 receiver.

Similar companies include Russound, Denon, and Sherwood.
