Designed by acclaimed industrial designer Ross Lovegrove, LS LUXE boasts a sculptural, distinctive visual identity akin to other products in the Ross Lovegrove collection. It redefines luxury in home audio, exemplifying a fusion of high-end acoustic performance, refined aesthetics, and user-centric innovation, tailored for discerning customers who value exceptional craftsmanship and cutting-edge technology.

Designed by Ross Lovegrove

Renowned for his innovative approach and flowing, sculptural forms, Ross Lovegrove brings a new dimension to sound. Through design that embraces both beauty and technological ingenuity, Lovegrove's ongoing collaboration with KEF is an exercise in aesthetic and engineering excellence. In LS LUXE, acoustics serve as the blueprint for design, shaping the form directly from sound principles. This design evolves beyond the LS Wireless Collection into a sculptural art piece, featuring organic forms and complementary geometries that create a distinctive, iconic presence—visually intelligent, elegant, and timeless.

LS LUXE is available in three colourways: Eclipse Black, Dusk Titanium, and Mineral White.

Advanced technology for unmatched acoustic performance

At the heart of LS LUXE sits a 12th generation 6.5-inch Uni-Q driver array with MAT. This signature technology delivers a true point-source configuration, with the tweeter precisely placed at the acoustic centre of the woofer, ensuring uniform sound dispersion throughout the room. At the same time, MAT functions as an acoustic black hole, absorbing 99% of the unwanted sound energy from the tweeter's rear radiation. This reduces interference and results in a cleaner, purer sound.

The Uni-Q assembly is mechanically decoupled from the cabinet to minimise panel vibrations that could otherwise generate audible distortion. Incorporated within the Uni-Q assembly is a bespoke flexible decoupling chassis arrangement that decouples and dampens the vibrations of the LMF motor, preventing them from exciting the cabinet panels.

Together, these innovations and refinements deliver an exceptionally wide sweet spot, uncannily natural sound with vanishingly low distortion.

Velocity Control Technology (VECO), KEF's sound correction technology first introduced in the XIO soundbar, is now featured in the LS LUXE. VECO utilises a closed-loop feedback amplification system, combining KEF's patented velocity sensor and a custom current-drive amplification stage within both primary and secondary speakers. The velocity sensor measures the real-time cone motion, feeding this data to the amplifier, which instantly corrects any discrepancies between the input signal and the cone's motion. This real-time monitoring and negative feedback loop ensures that the signal reaching the driver's voice coil includes both the intended musical signal and necessary corrections, significantly reducing distortion and compression. The result is pristine clarity and a more linear, accurate bass performance at all times.

To further refine performance, KEF's MIE—a proprietary suite of DSP algorithms—has been specially tuned for the LS LUXE, enhancing sound integrity, detail, and accuracy. This custom implementation is tailored specifically to suit the LS LUXE's acoustic and electronics package, providing excellent dynamic control that ensures consistent tonality regardless of playback level or duration.

LS LUXE features a highly optimised package of 100W Class AB and 280W Class D current-drive amplifiers in each speaker, which directly control the cone's motion by regulating the current delivered to the primary voice coils of the tweeter and the LMF drivers, respectively. This design results in lower distortion and a cleaner sound.

Performance by design

LS LUXE features a cabinet constructed from a highly durable and solid material that reduces the need for internal bracing, maximising acoustic volume in a compact form. Its smooth, low-diffraction rounded cabinet design further optimises acoustic performance, ensuring an exceptional listening experience.

Connect quickly, stream smoothly

LS LUXE utilises the class-leading W2 Wireless Platform that drives the LS Wireless Collection, offering seamless access to a variety of music services, including Tidal, Amazon Music, Qobuz, Deezer, and more. You can also stream directly from native apps like Spotify Connect, Tidal Connect, Qobuz Connect, and QPlay, ensuring full fidelity in your listening experience. When using AirPlay or Google Cast, you can stream to multiple speakers, so you can play music all over your space.

LS LUXE includes wired connections for your TV, CD player, and game console, featuring HDMI eARC, analogue, optical, and coaxial inputs. Each of the two speakers also has a dedicated output for adding one or two KEF subwoofers. Additionally, LS LUXE supports both wired and wireless interspeaker connections, allowing for flexible placement. It can play your personal music collection from a compatible NAS drive or music server. Audiophiles will appreciate the extensive file support, accommodating lossless formats up to 24-bit/384kHz (PCM) and DSD.

Complete control made simple

The KEF Connect app walks you through the setup and controls the system and playback navigation, with intuitive sound settings so you can adjust LS LUXE to best suit your room.

With its Room EQ DSP, LS LUXE can be fine-tuned to your room and personal taste without the need for a degree in acoustic engineering. "Normal Mode" is designed to guide you through the process with simple questions—all you might need is a tape measure. For those seeking greater control, "Expert Mode" allows you to configure EQ preferences with precision, enabling fine-tuning of the EQ in dB for experienced users. For easy integration of a KEF subwoofer with LS LUXE, Room EQ includes subwoofer presets for the best possible system performance.

LS LUXE also comes with a host of other user-friendly features, including volume settings, sensitivity adjustments, the ability to select a source to wake the system, and more.

Take your setup to the next level

LS LUXE is complemented by a range of optional accessories. The specially designed S-LUXE floor stands feature a cable management system that conceals wires and an integrated mounting system for secure speaker attachment, creating an optimal platform for performance. The K-Stream interspeaker cable ensures high-resolution data transfer between the primary and secondary speakers. At 8 metres long, it offers enhanced flexibility for placement compared to the standard interspeaker cable. Additionally, the KW1 wireless subwoofer adapter kit allows for seamless connections between KEF subwoofers and LS LUXE, eliminating the need for cables and enhancing the audio experience.
