SX Wireless Music System
Rediscover stereo. Rediscover music.

LSX is the sound system for how we listen to music now: a true two-box wireless music system engineered to deliver high resolution audio with breath-taking clarity from elegantly compact speakers.
LSX uses advanced wireless technology to retain the decades old audio principle that two speakers are better than one. LSX gives music space to breathe in glorious, full-bodied, wide bandwidth stereo.

Half a century of innovation
Since 1961, KEF has been a key driver of innovation in the audio world. Its unerring desire for improvement continues to lead to cutting-edge developments such as the Uni-Q® driver array. This relentless drive for development saw the 2011 launch of the incredibly successful LS50 loudspeaker, which was complemented by the exceptional LS50 Wireless. LSX expands upon this legacy, showing that even compact loudspeakers can deliver detailed, realistic sound.

Going truly wireless
LSX is completely wireless, both from the source and between the loudspeakers thanks to KEF’s proprietary wireless technology.
For Apple® customers, LSX features (from January 19) AirPlay® 2 which allow it to seamlessly and wirelessly operate with Mac®, iPhone®, iPad® and Apple TV® products. AirPlay 2 also enables the use of multiple LSX in different rooms and integrates with Siri®.
Wireless connections provide access to all the music on earth, with integrated access to Spotify® Connect and Tidal® using 2.4GHz/5GHz dual band wi-fi connectivity. For any other mobile music source, LSX also features Bluetooth™ 4.2 with the high quality aptX™ codec from Qualcomm®.

Perfect for TV
LSX contains the optical TOSLINK connector found on most flat-screen TV’s. Combined with its two-box form factor, LSX is an ideal TV solution and will render TV sound with all of the atmosphere and clarity required to make a truly transformative experience.

The technology behind LSX
LSX is the beneficiary of over five decades of KEF’s acoustic know-how. This includes unique technologies such as the Uni-Q driver array, which has been continually refined and improved for three decades. Here it works in harmony with KEF’s highly advanced Music Integrity Engine™, a cutting-edge collection of bespoke Digital Signal Processing algorithms that help these compact loudspeakers deliver transparent bass with great extension, as well as providing phase correction and distortion reduction. The result: perfectly accurate sound across a wider ‘sweet spot’.

Power and flexibility
LSX sports four Class-D amplifiers, one for each of the drive units, alongside dedicated DACs, providing high-end digital signal path of up to 96kHz/24bit, using the optional wired connection between the two speakers, or 48kHz/24bit in completely wireless operation. It also offers AUX and TOSLINK Optical connections.

Simplicity itself
LSX is reassuringly simple to set up, and incredibly intuitive to operate. Connecting to Wi-Fi takes mere moments via the intuitive KEF Control app. The app also allows LSX to receive over-the-air firmware and features updates. KEF’s optional Stream app enables use of Tidal and DLNA streaming.

Look and feel
LSX has been beautifully designed by KEF and the renowned industrial designer Michael Young. It is available in a choice of five unique colours, all of which use KEF’s tone on tone concept where elements such as the tweeter are colour matched to the finish. And LSX doesn’t just look great, it feels wonderful too, thanks to the use of luxury fabric from the innovative Danish textile manufacturer Kvadrat.

The result is a cutting-edge, high-performance Wireless Music System that sounds, looks and feels like nothing else. With LSX, listeners can experience natural and full-bodied KEF sound with all the space and depth that makes listening to music so transformative.
