KEF LS60 Wireless Review

In the decade since the launch of the LS50, in celebration of KEF’s 50th birthday, there have been rumors about a floor stander to complement the popular bookshelf model. But whatever these wishful thinkers had in mind, I’m sure it wasn’t as outlandish as the LS60 Wireless. As the name indicates, it’s both a nod to the 60th anniversary of the brand and its technical evolution by incorporating active electronics – DSP, DAC, and amplification – and streaming. Read our KEF LS60 Wireless Review.

The result is a pair of matched speakers that connect wirelessly (up to 96kHz/24-bit) or wired (up to 192kHz). No further kit is required; it is just a power outlet per speaker. But don’t wander off muttering ‘this isn’t real hi-fi’. Sure enough, at £ the LS60 Wireless isn’t ‘entry level’, but it might still be the most accessible or realistic way to get something akin to a KEF Blade parked in your living room.

KEF LS60 Wireless Review


Facing the super-slender but not superlight 32kg LS60 Wireless, it’s hard not to be impressed. At barely 13cm broad, it’s remarkable that KEF has managed to fit a 100mm Uni-Q driver into the baffle. The 109cm height certainly makes for unusual proportions for a loudspeaker. Still, visually, this ‘way of the monolith’ does work – even if you add in the broader plinth, which is necessary to keep the LS60 Wireless stable.

Three color finishes are offered, including the Royal Blue with gold-colored Uni-Q pictured here, but it’s the small footprint that’s the real design statement. Of course, while this brings more flexibility as to where you might choose to place the LS60 Wireless, the presence of side-firing woofers also means you should be mindful of adjacent walls – and although there’s some mitigation for this in the speakers’ accompanying app, there’s no global ‘room correction’ on offer.

Impressive as the LS60 Wireless looks, it’s in the technology where KEF has moved the goalposts out of the football field and into the car park. The Maidstone-based company has leveraged a number of its proven concepts, including the 12th-generation coaxial, time-aligned Uni-Q driver with rear output-absorbing metamaterial disc and, from the Blade flagship, pairs of force-cancelling woofers to complete this Single Apparent Source (SAS) design.

‘Its full-bodied mid is ideal for crunchy guitar playing’

However, as the LS60 Wireless is much smaller, KEF couldn’t use the Blade’s passive bass drivers. Instead, it incorporates the Uni-Core array first seen in the EISA Award-winning active KC62 subwoofer, where two long-throw woofers are planted back-to-back and use differently sized, overlapping voice coils to keep the unit compact. The LS60 Wireless contains two such arrays for four 135mm drivers.

The three-way ensemble is then governed by phase-corrected crossovers in DSP and three amplifiers. KEF selected 500W and 100W Class D modules for the bass and midrange sections, respectively, but a ‘traditional’ 100W-rated Class A/B amp for the tweeter.


Regarding connections and streaming, the LS60 Wireless takes its cues from the LS50 Wireless II. This includes an HDMI ARC input, next to optical and coaxial digital inputs, plus an analog RCA input to connect any legacy line source (including a turntable and phono preamp). With the addition of KEF’s second-generation W2 streaming platform, driven by the KEF Connect app [see boxout, p51], the platform extends to Chromecast, AirPlay 2 and Roon compatibility, Spotify Connect, UPnP, and Bluetooth. All told, you’re set to stream music in any way you wish.

Now, if you are wondering if KEF might be contemplating a passive version of the LS60, then, well, don’t bother. KEF’s VP of Technology, Jack Oclee-Brown, is adamant it won’t happen. The only way the slim design of the LS60 Wireless can function is through DSP control and the active Uni-Core force-cancelling woofers – the same just can’t be done passively, we’re told. ‘In terms of absolute performance and flexibility, active has a significant advantage.’

Even though these are reasonably heavy loudspeakers, installing the LS60 Wireless proved refreshingly easy–partly thanks to some nifty packaging but mainly because of the well-designed app. After setting the duo up in my room, it took only a few minutes to start listening.

Curious about the LS60 Wireless’s low-end performance and whether the single-apparent-source concept could work with slender units like these, I selected a wide-ranging playlist consisting of dynamic, rocking content. I listened back-to-back to The Killers’ moving portrayal of American Midwestern life on Pressure Machine [Island Records] and the rousing Fear Of The Dawn album [Third Man Records] that Jack White released earlier this year. Normally, I would use Roon for this, but as the LS60 Wireless’s certification was not ready then, I streamed the 96kHz/24-bit FLAC files via the ‘universal’ Bubble UPnP app.

Rock ’n’ roll proved not a bad genre for these speakers, as it encouraged them to show off an ability to render bass drums with a punch and present a full-bodied midrange ideal for crunchy, overdriven guitars. White’s opening track, ‘Taking Me Back’, impressed with the feeling of control from the speakers, with well-defined bass and snare drums that seemed to stop and start on a dime. And when the track shifted into a higher gear, there was no hesitation on the part of the LS60 Wireless to follow suit.

The Killers’ ‘In The Car Outside’ and ‘Quiet Town’ have a slightly cleaner sound that didn’t stress the system’s four Uni-Core woofers. Still, it did allow me to appreciate the speakers’ coherence, presenting a broad soundstage that highlighted, especially, the vocals of singer Brandon Flowers.

Be warned, though. It’s tempting to keep increasing the volume because these DSP-controlled speakers keep the performance balanced and safe. Is there a hint of compression when you hit stratospheric volumes? Possibly, although at that point, rattling furniture and angry neighbors are likely to be more immediate concerns.


The LS60 Wireless’s HDMI ARC connection makes it ready for TV sound, where its ability to put out a massive but controlled low-end and roll along with deliberately dynamic content (there are a lot of explosions and gunshots on telly these days) turned out to be a boon. Additionally, even a music-minded diet can benefit from Blu-ray – John Williams’ The Berlin Concert [Deutsche Grammophon 00028948617135] lets you enjoy the audience reaction – missing on the other media versions – when ‘The Imperial March’ from Star Wars: The Empire Strikes Back starts up.

And boy, does it get going. KEF’s active pairing demonstrates its acumen in the threatening opening parts and the slow build-up in the middle of the piece. The sense of depth, especially when the French Horns resound, could almost have convinced me I was present in the Philharmoniker concert hall, where the recording was made – if I wasn’t watching it on the screen before me. I guess that’s one of the shortfalls of live concert films.


More refined, low-key songs from The Killers’ Pressure Machine, such as ‘West Hills’ and ‘Runaway Horses’, featuring singer/songwriter Phoebe Bridgers, display another side to the LS60 Wireless. Although the speakers tend towards the neutral KEF ‘sound’, eschewing any treble lift that will cause your ears to prick, they do present music in a naturalistic fashion and with a light touch, which means you get the feeling that what you’re listening to is close to what the artist intended.

With, for example, KEF’s passive LS50 Meta, this is one of the key reasons why it’s important to match the speakers with complementary electronics. Of course, there’s no such worry with the LS60 Wireless and its built-in and complementary electronics. And the success of this holistic approach is revealed in the speakers’ mix of subtle detail and deep, tight, glorious bass.



With its line/digital inputs and fully integrated Class AB and Class D amplifiers, KEF’s LS60 Wireless has no meaningful ‘sensitivity’ that might be compared with a standard passive loudspeaker. Neither does it have any meaningful ‘impedance’ – the internal amplifiers are certainly driving a reactive load (the Uni-Q and bass units) but are direct-coupled – there is no passive crossover here – and cannot be swapped out for amplifiers of the user’s choosing. The forward responses are plotted here [with all eq. Adjustments defeated, see Graph 1 below] are only arbitrarily referenced to 90dB SPL/1kHz but show a strong upper bass and gently declining mid/presence. The 4.5dB kick upwards between 12kHz-18kHz is largely responsible for the ±2.5dB and ±2.3dB response errors, but pair matching is a tight 0.9dB from 800Hz-16kHz. The sharp breakup of the Uni-Q dome – just inside the 96kHz sampling bandwidth – at 44.8kHz (+4dB more vigorous in one speaker and ~14dB higher than the mean mid-band level) is revealed here in addition to some mild response ripples between 500Hz-1.5kHz. Both are visible in the CSD waterfall [see Graph 2], revealing the associated resonances, but the band from 2-20kHz is very clean indeed, courtesy of MAT.

The venting up via the plinth and out from the rear of the connection panel is for cooling purposes only, not for bass loading or tuning. The two pairs of 135mm ‘Uni-Core Force Cancelling’ woofers work into a sealed enclosure, offering a 30Hz-380Hz bandwidth (–6dB) and a combined, diffraction-corrected bass extension of 34Hz. This is better (lower) than might be achieved from a purely passive loudspeaker of similar complement and dimensions. However, that’s just one advantage of KEF’s actively-driven, DSP-governed bass tuning. Through-speaker latency is ~15msec while harmonic distortion is a reasonably uniform 0.3-0.5% (100Hz-10kHz re. 96dB SPL) – another benefit of this sophisticated digital/active configuration. PM

Launched for KEF’s 60th anniversary, these all-in-one streaming stereo speakers are special. They’re elegantly slim – remarkably so, given that they have 1,400W of combined power – and will play from virtually any source up to 24-bit/192kHz. There’s support for AirPlay 2, Google Chromecast, Spotify Connect, and Tidal Connect, to name a few, plus inputs for HDMI (eARC), optical, coax, Aux-in, and a subwoofer, not that you’ll need one.

The speaker configuration boasts a single Uni-Q driver – with a 19mm tweeter sat in the middle of the 10cm driver – and four back-to-back 5.25-inch drivers that brilliantly enable the low, mid, and high frequencies of whatever you’re playing to radiate from a single point, creating a huge soundstage and virtually no sweet spot.

Whatever I played through the LS60 Wireless sounded gobsmackingly good, and I’m in awe of how well the slender speakers handled lower frequencies. The timing and authority are truly remarkable for a streaming system, with the scale and power of a full orchestra and the nuance of a single instrument both thrillingly present. Spending time at home with speakers as good as these was an absolute privilege.

How big? Floorstanding speakers dominate most living rooms but offer exceptional sound across a vast soundstage. Cheaper models may be loud but can cause nasty vibrations if design corners have been cut. The best designs have internal bracing, which prevents resonance from coloring the sound.

Speaker and amp pairing It’s rare to find completely incompatible speakers and amps these days, but before you buy, do check that the ohms of both are compatible (speakers usually carry ratings between four and eight ohms; amps typically four to 16 ohms) and – to make a huge generalization – that your amplifier is 50 percent more powerful than your speakers.

Speaker positions: Floorstanding speakers are designed to project sound at your ear level when sitting. Ideally, you should keep the speakers well-spaced and at least 30cm away from any surfaces to get the best result.


KEF’s slender LS60 Wireless feels revolutionary and demonstrates to the world what the future of hi-fi could look like. Utilizing a range of the brand’s in-house innovations, including the space-saving Uni-Core bass driver technology from the KC62 subwoofer, 12th-generation Uni-Q driver, and single-apparent-source design from its mighty Blade, this active floor stander offers incredible bass, tangible power, and immaculate imaging. Furthermore, adapting the software platform from KEF’s LS50 Wireless Il bookshelf model means the LS60 carries the same exhaustive streaming options, including AirPlay 2 and Roon, plus user-friendly app-based control. Put simply, there’s nothing comparable out there all buyers need to do is pick a colour.

It’s hard to fault the LS60 Wireless, outside of its absence of any room correction platform. KEF’s slim speaker does perform like a compact version of the Blade(s) without the hassle of hunting for matching sources or amplification. The modern looks and integrated approach might put off traditional hi-fi buffs, but the LS60 Wireless is truly high fidelity for people who just want to enjoy their music.

Big, expensive floor-standing speakers aren’t usually the kind of thing we’d honor with a place in the hallowed Hot Five… but it’s impossible not to make an exception for KEF’s LS60 Wireless. While most floor standers are part of a system of separates, these meter-tall towers need nothing more than a power cable to get up and running, which makes this about the most minimalist hi-fi setup ever.

The 1400W pairing requires no external amplification, and there’s Bluetooth and Wi-Fi on board, with support for Spotify Connect, Tidal Connect, AirPlay 2, and Google Chromecast, so all you need to do is connect your phone and fire up your streaming app of choice.

Of course, the old-fashioned inputs are still there if you want them: there’s RCA, coaxial, optical, and even HDMI eARC for your telly. However, you choose to feed them, though. KEF’s Uni-Q drivers and Single Apparent Source tech make it sound like all the frequencies come from the same point – the audiophile’s acoustic holy grail. They even come in three colors to annoy the black-only hi-fi purists.

As hot as… an audiophile’s temper

…Hi-Fi audio without the faff

Got a spare £ kicking about? Well, that will be enough for you to invest in legendary audio brand Kef’s latest speakers. Besides being staggeringly expensive, the LS60 is among the smartest hi-fi speaker systems available. It uses apparent source technology, which provides the full audio spectrum of lows, mids, and highs from a single point rather than multiple ones. This achieves a better immersion for music and movies, and with the LS60, it can be achieved wirelessly, without all the usual gubbins of an amplifier and cables.
