LSX by KEF offers a completely wireless experience, both between the source and the loudspeakers, thanks to KEF's proprietary technology. With dual-band Wi-Fi connectivity, music can be accessed from Spotify Connect and TIDAL effortlessly. Bluetooth 4.2 with Qualcomm aptX codec allows seamless streaming from any other mobile device, including Apple products, which also benefit from Apple AirPlay 2 support. LSX enables multi-room setups and control via Siri, and it serves as an ideal TV sound solution with its optical TOSLINK connector. Key features include an acoustic design with a 4.5" Uni-Q driver and FEA-designed cabinet, KEF's Music Integrity Engine, four Class D amplifiers, and dedicated DACs for high-fidelity audio. Adjustable EQ settings via the KEF control app, various connectivity options including Wi-Fi, Bluetooth, optical input, and AUX, with a design by Michael Young and luxury fabric from Kvadrat. The technology behind LSX leverages over five decades of KEF's expertise, featuring the Uni-Q driver array and the Music Integrity Engine. Setup is simple via the KEF Control app or AirPlay 2, and LSX receives firmware updates over-the-air.
