KEF LS Luxe review

KEF is to active speaker systems what Spain is to international football at the moment.

From the Award-winning LSX II active wireless stereo system to the Bluetooth-ready Coda W active standmounts, the brand’s blending of features and performance is where KEF has really shone over the past few years.

Acting as a step-up from the fiercely talented (and multiple Award-winning) LS50 Wireless II, the new KEF LS Luxe once again integrates amplification and streaming into a compact stereo system, incorporating all of KEF’s know-how into what is a decidedly more premium standmount package than the company has made before.

At £3500 / $4000 / AU$6375, we’re moving into more high-end territory compared with the £2199 / $2999 / AU$4295 LS50 Wireless II, with KEF claiming that the LS Luxe is the result of six years of research and development. Given how well the product performs, that time has been extremely well spent.

Build & design

“A presence designed to hold the room before a single note is played.”

That’s how KEF has described the LS Luxe’s looks, and while subjective tastes are likely to dictate exactly how you feel about the cabinets’ distinctive styling, there’s no question that the speakers themselves are capable of drawing the eye before they even have a chance to grab you by the ears.

The cabinet exteriors have been designed in collaboration with Ross Lovegrove, the Welsh designer with whom KEF previously joined forces when crafting the mighty Muon floorstanders, the portable Muo Bluetooth speaker, and the distinctive Mu headphones/earbuds range.

The LS Luxe very much continues the distinctive design language of Lovegrove’s previous collaborations, typified by their rounded, edgeless cabinets which, when sporting their ‘Dusk Titanium’ finish, positively gleam thanks to their luxuriously polished exteriors. That pebble-like speaker design will not be for everyone, and it may depend on which of the three finishes – Eclipse Black, Dusk Titanium or Mineral White – you choose.

What’s less up for debate is the tangible high quality of the speakers’ construction.

Pick up each speaker and you’ll feel how weighty and substantial they are, with everything about the LS Luxe – from the finish of their curved shells to the seamless integration of the driver array and front baffle – speaking of a product constructed with genuine care.

That design isn’t just for show, either. That curved form aims to improve performance by reducing the build up of internal standing waves within the cabinet, whereas the use of durable ‘Bulk Moulded Compound’ (BMC) composite material reduces the need for excessive internal bracing, allowing for greater internal volume within the speakers to aid their low-frequency performance.

Turn the speakers around and you’ll see an equally distinctively designed aluminium heatsink, which is crafted to provide a greater surface area to more efficiently dissipate heat generated by the active electronics within. A flared reflex port also sits at the rear of each unit, designed using KEF’s ‘Flexible Port Technology’ where the port’s walls use a flexible material to reduce internal resonances.

At the heart of each speaker is KEF’s 12th-generation Uni-Q driver array, where the tweeter sits in the middle of the mid/bass unit in pursuit of more even sonic dispersion, better integration and improved time alignment. KEF’s now-familiar Metamaterial Absorption Technology (MAT), which absorbs rearward sound from the back of the tweeter dome, is also incorporated in pursuit of a cleaner, purer sound.

In terms of power, 280 watts of Class D amplification are directed to powering the mid/bass unit, while 100 watts of Class A/B amplification drives the tweeter.

That Uni-Q driver assembly is mechanically decoupled from the cabinet to reduce panel vibrations. Incorporated within the driver assembly is a decoupling chassis that damps the vibrations of the motor system, preventing them from feeding into the cabinet panels. The aim is to improve clarity and reduce distortion.

KEF has included a suitably premium-feeling remote control with the LS Luxe, as well as a speaker interconnect cable to optimise performance and an HDMI cable for use with your TV or home cinema set-up. Two power cables are also included, with both speakers requiring mains power – something to bear in mind when setting up your system.

What you don’t get included in the LS Luxe’s standard sale price are dedicated stands. If you want to get hold of a pair, KEF sells a set of S-Luxe stands for £800 / $800 / AU$1230 which you’ll have to put together yourself and screw into the base of each speaker.

That’s a considerable outlay on top of an already premium purchase, but our testing found that these stands help to optimise performance, secure the speakers in place and, thanks to their complementary aesthetic, and help them look their best. In other words, we feel that these stands would be money well spent.

Features

The KEF LS Luxe offers a suitably well-stocked connectivity suite to go with the system’s premium outlay.

KEF has been generous with the array of physical connectivity options on offer. Around the back of the primary speaker unit, you’ll find HDMI eARC, 3.5mm analogue, optical and coaxial inputs, while each of the two speakers has a dedicated output for adding a single subwoofer or a pair if necessary.

On the streaming side, the system uses KEF’s W2 Wireless Platform, which we’ve already experienced in the brand’s established LS wireless range. This grants access to popular streaming services such as Tidal Connect, Spotify Connect, Qobuz Connect and Deezer, along with internet radio.

There’s also the further convenience of AirPlay 2, Google Chromecast and Bluetooth 5.3, while UPnP compatibility means you can stream hi-res music from a connected external NAS drive. Roon Ready support is slated to arrive in 2027.

Hi-res file support depends on how you choose to set up and listen, with KEF’s new system capable of handling PCM files up to 24-bit/384kHz alongside DSD128. If you’re using a wireless connection between your speakers, those higher resolution files are internally downsampled to 24-bit/96kHz, whereas connecting the master and slave speakers using the included interconnect cable pushes playback up to 24-bit/192kHz.

Further technologies seek to enhance the LS Luxe’s performance beyond mere hardware. This is the first speaker product to feature KEF’s ‘Velocity Control Technology’, as seen in the brand’s five-star XIO soundbar, where the speed of cone movement is measured, and any differences between that and the expected value are compensated for in real time. The result is lower distortion levels.

Additionally, a proprietary ‘Music Integrity Engine’ tech uses digital signal processing algorithms to maintain accuracy and tonality no matter the volume at which the LS Luxe is played.

For getting the most out of your shiny new set-up, you’ll want to download the comprehensive and easy-to-use KEF Connect app, from which you’ll be able to control and set up your speakers. You can tweak the sound yourself using a customisable equaliser, while KEF’s ‘Room EQ’ digital signal processing helps you fine-tune your sound to your listening space.

It’s worth spending a bit of time with the app’s calibration settings, as, while the LS Luxe isn’t a prima donna in terms of positioning, you’ll certainly notice a difference when you tinker with the app’s various parameters, such as room size, the distance you’ve placed your speakers from your wall, and how damped your listening space is.

Sound

We decide to give our review sample the best chance possible to showcase its talents by screwing each speaker tightly to their dedicated S-Luxe stands, using the provided inter-speaker cable for the highest transmission rate possible (24-bit/192kHz), and kicking off with some hi-res wireless streaming via Tidal.

Naturally, we experiment with positioning, and find that they perform best with the speakers firing straight ahead and sitting roughly 30cm from the back wall of our 3m x 4m x 7m listening room.

Thanks in part to that updated Uni-Q driver array, the LS Luxe is gratifyingly unfussy about placement, producing a supremely well-integrated sound that remains consistent no matter our listening position.

What we discover is a wireless system with poise, control and, dare we say it, genuine grace. Like a fine wine or one of those acclaimed French arthouse movies, the KEF LS Luxe needs a little time for its true spectrum of talents to be appreciated.

The LS Luxe does not reach out and grab us by our lapels; instead, it reproduces our music with an even-handed, mature yet authoritative nature that slowly but inevitably places us under its bewitching spell.

This is a sonic signature we’ve heard before, from the more affordable LSX II and LSX II LT stereo systems and the established LS50 Wireless II. But the Luxe piles on extra helpings of detail and precision to that confident, articulate presentation we’ve experienced from KEF in recent years.

Listen to Massive Attack’s Atlas Air, and you’ll get a clear indication that for clarity, textural detail and overall scale, the LS Luxe is considerably ahead of the LS50 Wireless II, anchored by a taut, authoritative bass reproduction that sinks low without sagging like a bulldog’s floppy jowls.

While what we’re dealing with is a standmount speaker system, the scale and authority showcased belie the Luxe’s compact form. We load up Hans Zimmer’s Why Do We Fall? from the Dark Knight Rises soundtrack, and our reward is a rendition that soars with so much power, scope and grandeur that it’s hard to resist the urge to don our cape and cowl and go out looking for bad guys to bring to justice.

Punch and panache live side by side, with the LS Luxe knitting music together so expertly that even truly demanding tracks can’t catch it napping. Whether it's the gale-force hurricane of Slipknot’s Before I Forget, the magisterial grandeur of Tchaikovsky’s 1812 Overture or the carefully curated strangeness of Yosi Horiko’s Bubbles, the Luxe barely breaks a sweat.

Interlocking rhythms are expressive and nimble, while dynamic ebbs and flows are communicated confidently without sounding artificial or overdone.

We use our Cyrus CDi player connected to the optical input to test the internal DAC, and again, that core character is firmly intact as we spin Jeff Buckley’s Grace, and the LS Luxe excels at revealing the intimacy, delicacy and emotion of the seminal record. We also connect the Luxe to the Cyrus using a 3.5mm to RCA adapter cable, and we continue to receive a high standard of performance.

While most of our listening is done using the S-Luxe stands, we also place the speakers on our tried-and-tested FS104 Signature plinths, and while the performance remains impressive, it isn’t as crisp and dynamic. The speakers themselves are just about compact enough to be placed on a desk, but at this premium price, they’re best suited to being listened to on stands.

Switching to Bluetooth will also result in an inevitable drop-off in clarity and precision, but the LS Luxe still retains its even, mature nature when playing through this less-than-ideal streaming medium. They do their best to shine, but it’s clear that we’re placing a limit on the system’s considerable abilities.

Verdict

The LS Luxe feels like another milestone in KEF’s recent history of providing outstanding wireless stereo speaker systems.

Yes, it’s a good deal more expensive than the LS50 Wireless II, and no, that distinctive curved design won’t be for everyone – but in terms of performance, this is a mightily impressive addition to KEF’s catalogue.

If you’re willing to pay that premium price – and fork out a bit extra for some dedicated stands to get the best out of them – then slick performance and outstanding sound will be your reward.
