Stereo.
Feel the performance.
With two speakers positioned apart from each other, you’ll experience music as a 3D soundstage, with the pin-point imaging and sense of presence that one-box systems miss. It’s the difference between just hearing music, and really feeling it.

Apple AirPlay 2*
LSX comes with Apple AirPlay 2 which, from a simple screen tap or request to Siri, unlocks the world of multi-room audio. You can wirelessly stream all your favourite music apps to your whole home with seamless control from your iPhone, iPad, and Mac.(*available in early 2019)

All the music
on earth.
With Spotify Connect and Tidal built in, all the music you love is at your fingertips. Stream from the cloud, or directly from a NAS drive or a computer through DLNA fully wirelessly at 48kHz/24bit resolution (or 96kHz/24bit using optional wired connection). Or simply use Bluetooth.

Easy listening.
With LSX, nothing gets between you and the music. Connecting to Wi-Fi takes moments with the KEF Control app and keeps abreast of the latest firmware, so your speakers are future-proofed and always up to date.

Sound
LSX utilises KEF’s advanced acoustic design technology, features that are usually reserved for much larger hi-fi speakers. Get ready for goosebump-inducing levels of sonic realism and accuracy.
Uni-Q.
The sweet spot just
got a lot wider.
LSX comes with KEF’s breakthrough Uni-Q driver array. By placing the tweeter at the centre of the midrange and bass cone, it radically improves stereo imaging. This not only makes music sound clear, detailed and lifelike, it does so across a wider listening area.

Contoured baffle.
Hear the music,
not the speaker.
Optimised using Finite Element Analysis, LSX’s contoured baffle improves sound dispersion, ensuring that sound waves travel outwards and are not reflected around the cabinet surface. The result? A purer sound, with less cabinet colouration.

DSP.
Small speakers,
big sound.
LSX uses KEF’s Music Integrity Engine™ – bespoke Digital Signal Processing that helps the speakers deliver transparent bass with great extension, while reducing distortion. So you can fill your room with rich, full-bodied sound.

LSX Wireless Music System Review |
"From Hendrix to Julia Stone, London Grammar to Rammstein, for what is not much larger than most desktop computer speakers, KEF's LSX have managed to mimic a loudspeaker that is much larger than itself. Remarkably well, in fact." |

"The company’s Uni-Q driver array, for example, improves stereo imaging and makes for a wider listening area. The speakers also feature Kef’s Music Integrity Engine, a group of DSP algorithms to time-correct and phase-align audio, making for a less muddy low end and overall clearer sound." |

LSX Wireless Music System 5 Star Review |
"We only need to hear the serene drum beat and guitar plucking duo of Nick Cave’s Jubilee Street to know that these KEFs do, to borrow lyrics from the song, “practice what they preach”. From the poised delivery of his first stanza, the LSX are clearly sonic descendants of the expressive, tonally-even and rhythmically astute LS50 Wireless." |

LSX Wireless Music System Review & Knockout Award |
"Music is not supposed to come out of a box this size and radiate outwards, its meant to come out of left and right speakers – that’s how its mixed. What I like about these speakers [the LSX] is these are speakers for people who don't know about hi-fi and don't want to know about hi-fi necessarily. You just set up and you go with music, and you can put them anywhere, and you can tweak their configuration within the app. And there are enough different kinds of inputs to satisfy nearly everybody’s need in modern life....
