KEF Manuals & User Guides

KEF is a distinguished British audio manufacturer founded in 1961 by Raymond Cooke in Maidstone, Kent. Renowned for its engineering excellence and acoustic innovation, KEF produces high-fidelity speakers, home theater systems, subwoofers, and headphones.

The brand is particularly famous for its signature Uni-Q driver array technology, which places the tweeter in the acoustic center of the midrange cone to deliver a uniquely wide and natural sound dispersion. Now a member of the Gold Peak Group (GP Acoustics), KEF continues to merge precision engineering with modern industrial design, offering products ranging from the iconic LS50 wireless speakers to architectural custom installation audio solutions.

• How do I register my KEF product for warranty?

  You can register your electrical KEF products to verify purchase and extend protection by creating a myKEF account on the official KEF website or by scanning the QR code included in your Quick Start Guide.

• What is the KEF Uni-Q driver array?

  Uni-Q is KEF's signature technology that places the tweeter in the acoustic center of the midrange cone. This single point source arrangement allows sound to disperse more evenly throughout the room, creating a wider and more natural soundstage.

• How do I reset my KEF wireless speakers?

  For many KEF wireless models like the Muo or LSX, you can reset the device by holding specific button combinations (such as the Power and Bluetooth buttons) for about 10 seconds, or via the KEF Connect app settings.

• Where can I find KEF user manuals?

  User manuals, datasheets, and firmware updates are available on the KEF Product Support page or can be downloaded here from our repository.
