The technology behind LSX
LSX is the beneciary of over ve decades of KEF’s acoustic know-how. This includes
unique technologies such as the Uni-Q driver array, which has been continually rened 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 exibility
LSX sports four Class-D ampliers, 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 oers 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 rmware 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 ve unique colours, all of
which use KEF’s tone on tone concept where elements such as the tweeter are colour matched to the nish. 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.
