KEF LS LUXE (Pair) - Black - White - Titanium

Description

A Sculptural Cabinet by Ross Lovegrove

The LS LUXE extends KEF's long collaboration with British industrial designer Ross Lovegrove, whose earlier work for the brand includes the MUON speakers, the Mu3 earphones, and the Mu7 headphones. The rounded, fluid cabinet is molded in BMC (bulk molding compound), a thermoset composite that provides high rigidity without heavy internal bracing — the internal acoustic volume stays intact in a compact footprint. The outer geometry minimizes edge diffraction, and the Uni-Q array is mechanically decoupled from the cabinet by a flexible chassis that isolates its vibrations from the enclosure.

12th-Generation Uni-Q Driver Array With MAT

The coaxial Uni-Q array combines a 25 mm vented aluminum dome tweeter mounted at the exact acoustic center of a 165 mm (6.5-inch) aluminum cone. Behind the tweeter, MAT (Metamaterial Absorption Technology) absorbs 99% of unwanted rear radiation to reduce distortion and coloration in the high frequencies. KEF rates the response at 42 Hz to 28 kHz (±3 dB), with extension down to 35 Hz (-6 dB) and a maximum SPL of 110 dB at 1 m.

Bi-Amplification With Closed-Loop Velocity Control (VECO)

Each speaker carries 380 W of internal amplification: 280 W of Class D current-drive amplification for the low/mid cone and 100 W of Class AB amplification for the tweeter. The LS LUXE is KEF's first speaker to use Velocity Control Technology (VECO), after its debut in the XIO soundbar — a closed-loop system that measures actual cone velocity with a sensor and feeds an instantaneous correction back into the amplifier before deviations turn into audible distortion. The Music Integrity Engine (MIE) DSP supervises tonal balance across all listening levels.

W2 Platform: Network, Inputs, and dual Subwoofer Output

The W2 wireless platform handles network playback up to 24-bit/384 kHz, with AirPlay, Google Cast, Spotify Connect, Tidal Connect, Qobuz Connect, Amazon Music, Deezer, Internet Radio, and podcasts. Bluetooth 5.3, dual-band Wi-Fi 6 (802.11ax), UPnP and NAS support, and Roon Ready support announced for 2027. Wired connectivity on the primary speaker: HDMI eARC (up to 24-bit/192 kHz), TOSLINK optical (24-bit/96 kHz), digital coaxial (24-bit/192 kHz), a 3.5 mm analog input, and an RCA subwoofer output — which the secondary speaker also carries, along with the interspeaker RJ45 line. The link between the two speakers is either wireless (resampled to 24-bit/96 kHz) or wired Ethernet (24-bit/192 kHz), and the optional K-Stream cable accepts up to 8 meters between the two units.

Common Questions

Why choose this product?

The LS LUXE is the most fully realized wireless system in KEF's LS range: the Ross Lovegrove sculpted cabinet, the 12th-generation Uni-Q with MAT, 380 W of bi-amplification, and closed-loop VECO motion control in a single box — no external amplifier or preamp required. It is the coherent pick for someone who wants a serious high-fidelity system and a finished object without building a traditional separates chain.

How do the two speakers communicate with each other?

Two options: wireless (resampled to 24-bit/96 kHz) or the included wired Ethernet cable (resampled to 24-bit/192 kHz). For an install where the two speakers sit far apart, the optional K-Stream cable accepts up to 8 meters between them while keeping the full 24-bit/192 kHz resolution.

Can I add a subwoofer?

Yes. The primary and secondary speakers each carry a dedicated RCA subwoofer output. The KEF Connect app includes crossover presets tuned for KEF subwoofers (KC62, KC92, Kube MIE, among others), and the optional KW1 wireless adapter kit adds a cable-free link to a KEF subwoofer.

Which audio resolutions are supported?

Network playback up to 24-bit/384 kHz (PCM and DSD). HDMI eARC and coaxial up to 24-bit/192 kHz. Optical up to 24-bit/96 kHz. Network formats: DSD, FLAC, WAV, AIFF, ALAC, AAC, WMA, MP3, M4A, LPCM, and Ogg Vorbis. Note: MQA decoding, which was on the LS50 Wireless II, is not supported on the LS LUXE.
