Audio manufacturer KEF is launching the LS LUXE wireless speaker set priced at $3,999.99, featuring a design collaboration with Ross Lovegrove and a patent-pending acoustic system called Velocity Control Technology. Developed as an ambitious creation for the luxury market, the system integrates the company’s 12th-generation 6.5-inch Uni-Q driver and aims to redefine domestic high-fidelity listening through advanced digital processing and custom amplification.
Acoustic Architecture and Driver Technology
At the core of the LS LUXE system is KEF’s 12th-generation 6.5-inch Uni-Q driver assembly, a component previously utilized in systems like the LS50. According to the company, the Uni-Q assembly uses a flexible chassis to mechanically decouple the components, isolating internal vibrations to maintain audio integrity. This hardware is paired with MAT Technology, which KEF states absorbs 99% of unwanted rear sound from the tweeter to eliminate distortion and widen the acoustic sweet spot. Grace Lo, President and Head of Global Marketing at KEF, stated, “At KEF, we have always aimed to redefine the listening experience and make it truly inspiring. LS LUXE is that vision realized.”
New to this hardware lineup is Velocity Control Technology, or VECO. First introduced in the XIO soundbar, VECO operates as a closed-loop system equipped with a velocity sensor that monitors the Uni-Q driver in real time. This sensor feeds operational data instantly to a custom amplifier designed to correct movement inconsistencies. Supporting this hardware is KEF’s proprietary Music Integrity Engine, which deploys finely tuned digital signal processing algorithms to preserve definition when the amplifiers operate under heavy workloads.
Amplifier Specifications and Connectivity
Each LS LUXE speaker houses a combination of a 100W Class AB and a 280W Class D current-drive amplifier. The hardware delivers a frequency range spanning 35 Hz to 47 kHz, alongside a frequency response ranging from 42 Hz to 28 kHz depending on user-selected equalizer settings. Built upon KEF’s W2 Wireless Platform, the speakers support lossless audio formats up to 24-bit/384kHz and multi-room audio distribution.
Users can access streaming services such as Tidal, Amazon Music, Qobuz, and Deezer directly via native applications using Spotify Connect, Tidal Connect, QPlay, AirPlay, or Google Cast. Physical connectivity options include HDMI eARC, analog, optical, and coaxial inputs. Each speaker also features a dedicated subwoofer output. Listeners can stream locally stored files from network-attached storage drives or music servers, accommodating both PCM formats up to 24-bit/384kHz and DSD.
Design Finishes and Customization Options
The visual presentation of the LS LUXE stems from an ongoing collaboration with designer Ross Lovegrove, continuing a design lineage that includes the Muon, Mu headphones, and the Muo portable speaker. The LS LUXE hardware is housed in a sculptural shell available in three distinct colorways: Dusk Titanium, Eclipse Black, and Mineral White. Manual control is handled via the included C3 Remote, while initial setup and configuration run through the KEF Connect App.
Did you know? Ross Lovegrove’s previous sculptural collaborations with KEF include the Muon loudspeaker system.
For custom installations, KEF offers optional S-LUXE floor stands that incorporate integrated cable management for a clean appearance. Additionally, the K-Stream interspeaker cable permits high-resolution audio transfer with up to eight meters of placement flexibility, while the KW1 wireless subwoofer adapter kit enables a cable-free link between the speakers and compatible subwoofers.
