Overview
KEF LSX Stereo Wireless Speakers Pair is specially designed with reference to LS50. After the huge success of LS50 Wireless, KEF has come up with LSX. LSX retains almost similar features as LS50 Wireless, utilising one amplifier for each driver - two amplifiers totalling 100 Watts in each speaker. A streaming preamplifier and DSP section, combined with a new incarnation of KEF's legendary Uni-Q driver array are nestled within an FEA designed cabinet with a curved front baffle, proudly displaying the unique heritage of the LS50 family.
KEF’s unique Music Integrity Engine™ combined with the point source technology of Uni-Q ensures that sound not only comes from a single point in space but all at the correct time. The result is a tighter sound, with a beat that can be followed and a soundstage where you can almost point to where the sound is coming from.
Wi-Fi & Bluetooth® Wirelessly access all the music in the world through Spotify® Connect, Tidal® or access a music library stored on a NAS drive via DLNA® and uPNP, or Bluetooth with Qualcomm® aptX™.
Apple® AirPlay® 2 will extend LSX to become part of a multi-room wireless music system, easily controlled from iOS devices.

Generating expert take…
KEF traces its roots to 1961, when British engineer Raymond Cooke founded the company in a modest Nissen hut on the grounds of the Kent Engineering and Foundry in Maidstone, England. A former BBC engineer and Wharfedale veteran, Cooke was driven by a passion for music and a commitment to technological innovation, aiming to reproduce sound as faithfully as the original performance. From its inception, KEF pioneered materials like foil-stiffened polystyrene diaphragms and Melinex tweeters in its debut K1 loudspeaker, setting a benchmark for engineering precision that propelled the brand to early acclaim.
KEF has long specialized in loudspeakers, establishing itself as a leader with iconic innovations such as the Uni-Q coaxial driver and computer-aided design techniques that revolutionized driver and enclosure development. While drive units supplied to other manufacturers fueled its growth, the brand's core output remains high-fidelity speakers across categories like floorstanders, bookshelves, and home theater systems, including early THX-approved setups. Active wireless models and reference-grade series extend its portfolio, though it eschews amplifiers, turntables, DACs, headphones, or cables.
Renowned for its science-driven heritage, KEF occupies a premium position in the hi-fi market, blending accessible high-end performance with cutting-edge technology. Collectors prize vintage BBC monitors and Bextrene-driver classics, while modern buyers seek its precise, natural soundstaging. Decades of awards affirm KEF's status as a respected innovator, appealing to discerning audiophiles who value engineering over hype.
