KEF has announced the KEF LS LUXE, a new wireless speaker system. Its sculptural cabinet design combines with a range of new and existing KEF acoustic technologies, including the company’s 12th-generation 6.5-inch Uni-Q driver with Metamaterial Absorption Technology (MAT) and the debut of Velocity Control Technology (VECO). These new models are available in Dusk Titanium, Eclipse Black and Mineral White finishes.
At the heart of the design is the a 12th generation 6.5-inch Uni-Q driver array with MAT, with its Uni-Q assembly being mechanically decoupled from the cabinet to minimise panel vibrations. The driver uses KEF’s new Velocity Control Technology (VECO), a closed-loop system that monitors the movement of the Uni-Q driver using a velocity sensor that feeds data to a dedicated amplifier in order to reduce bass distortion. 
KEF’s Music Integrity Engine (MIE) digital signal processing is used to maintain consistent performance across different listening levels. With each LMF speaker powered by a 280W Class D current-drive amplifier and each tweeter powered by a 100W Class AB amplifier.
The LS LUXE is built on KEF’s W2 wireless platform and supports streaming services including Tidal, Amazon Music, Qobuz and Deezer, alongside Spotify Connect, Tidal Connect, Apple AirPlay, Google Cast and QPlay. Roon Ready compatibility is scheduled to become available in 2027. File support includes; PCM files up to 24-bit/384KHz and DSD from compatible music servers or NAS drives.
The LS LUXE can be controlled using the supplied C3 remote and configured using the KEF Connect app, which includes Normal and Expert setup modes along with Room EQ DSP for room optimisation.
Wired signal connectivity via the primary speaker includes; 1 x HDMI eARC, 1 x 3.5mm stereo analogue, 1 x optical and 1 x coaxial inputs. While each speaker also features a dedicated subwoofer output. Other connectivity includes; RJ45 network and RJ45 interspeaker.
Optional accessories include; the S-LUXE floor stands with integrated cable management, the K-Stream 8 meter interspeaker cable, and the KW1 wireless subwoofer adapter kit for cable-free connection to compatible KEF subwoofers.
