KEF is one of the finest purveyors of British hi-fi, with an illustrious heritage that stretches back more than 50 years. The company has had a few ups and downs in that time, but it hasn't lost its talent for engineering classy, superb-sounding speakers, as you'll see from the list below.
We've been reviewing KEF speakers since our earliest days of publication, so we know what's good and what's not. All of the below have been through our usual rigorous testing process and come out as highly acclaimed, earning either four or the full five stars, so you can be sure they'll do you proud.
They're all great, then, but that doesn't mean they're all the same. Read on and you'll discover which are the right ones for you.
How to choose the best KEF speakers for you
Why you can trust What Hi-Fi? Our expert team reviews products in dedicated test rooms, to help you make the best choice for your budget. Find out more about how we test.
Most of KEF's speakers feature the firm's clever and now-iconic Uni-Q driver. Rather than having a separately mounted tweeter and midrange driver, the tweeter is set into the centre of the mid. A simple idea – but it's what sets the company apart from the pack.
More importantly, KEF has kept pace with the times and diversified into wireless speakers alongside passive speakers, including modern wireless all-in-one streaming systems that offer a full system without the need for multiple boxes.
With more choice than ever, you might be wondering where to start. The good news is that we've done the legwork and rounded up the very best that KEF has to offer at the moment.
Passive stereo speakers
The original LS50 speakers had little wrong with them but after eight years, KEF figured they deserved a fresh look. With the LS50 Meta, the British audio brand has delivered a truly worthy upgrade.
The LS50’s Uni-Q driver array, where the tweeter sits in the throat of the mid/bass unit, has been thoroughly reworked, taking in all the refinements that KEF has developed over the past eight years and adding its much-heralded Metamaterial Absorption Technology (MAT). MAT is KEF’s way of coping with the sound that comes off the back of the tweeter dome; a plastic circular maze of tubes on the back promising greater absorption for cleaner, less distorted highs.
While the basic sonic character is instantly familiar, the Meta speakers have gained a level of clarity and finesse the originals only hinted at, sounding clean while still offering muscle and dynamics. Sonically, they're everything you want KEF speakers to be, offering that balance and substance that only the finest performers can achieve.
We loved the originals, but the LS50 Meta takes the performance to a notably higher - and Award-winning - level. The best of the best.

KEF's innovative MAT took the performance of many of its speakers to the next level. It was only a matter of time before the tech was integrated into its 2023 R Series of speakers, and when it was incorporated into the premium R3 Meta standmounter (combined with the Uni-Q driver array), the resulting success felt inevitable.
The three-way R3 Meta are gorgeous-looking speakers with impeccable finish and build quality. KEF's 12th-generation Uni-Q driver array has been tweaked to accommodate the puck-sized MAT contraption (which absorbs 99 per cent of unwanted back radiation from the tweeter), and the resulting sound is astonishingly clear and insightful.
The KEFs have a graceful nature to them that hides just how accomplished they are, so much so that you'll find them a pleasure to listen to no matter the genre. They’re wonderfully transparent, at ease with the full gamut of musical diversity: heavy metal, ’90s pop and classical works are all played over our testing period and the KEFs take it all in stride, simply relaying the music as faithfully as possible.
If you want bigger, bolder sound than the LS50 Meta (and can afford the next step up), this R3 Meta comes with a hearty recommendation.

Much like the new KEF R3 Meta speakers in this list, KEF has updated its higher-end Reference 1 speaker with its innovative Metamaterial Absorption Technology (MAT), which absorbs around 99 per cent of the unwanted, distorting sound waves from the back of the tweeter. And once again, it's done with great success.
Adding MAT to KEF’s trademark Uni-Q driver array – where the 25mm aluminium tweeter sits in the throat of the midrange unit – is a lot more involved than just plonking the tech on the back of the driver. In the Reference 1 Meta, it involves significant re-engineering. The company has taken the opportunity to add a whole host of refinements to the array’s structure, motor system and geometry to eke out a better performance. The Uni-Q array is even decoupled from the Reference 1 Meta’s beautifully built cabinet to reduce the amount of vibration transmitted into the enclosure.
And KEF’s engineers have done a stellar job with these speakers. The original Reference 1 were great, but the sonic refinements brought about by the Meta upgrade are significant. The soundstage is expansive and layered, they deliver the music’s dynamic shifts with conviction, they're beautifully transparent and tonally balanced and rhythmically agile all at once.
At the time of writing, it is hard to think of a more rounded alternative for anything at this high-end level. Take care with the partnering system and these KEF speakers are sure to entertain.

Wireless stereo speaker systems
Aesthetically, not much has changed between the LSX II and their predecessors, the wonderfully expressive original LSX model. The all-in-one speakers, with amplification, streaming and connectivity all built in, look identical to their predecessors and feature the same 11th Generation Uni-Q driver, too, but there are some big changes elsewhere that take things to a new level.
Namely, more connection options. The first is HDMI ARC and the second is a USB-C connection for connecting to a TV and laptop respectively. Like other KEF wireless speaker systems, they also have an Ethernet port for connecting the speakers directly to your router, or a switch and a second port which you use to connect the supplied ethernet cable between the speakers. This is required if you want native playback of 24-bit/96kHz digital music files (anything higher than this is downsampled to 24-bit/96kHz).
The LSX II turn in a confident musical performance, with a real sense of refinement. They retain a nice sense of rhythm, with bags of warmth. KEF's winning formula just got that little bit better, and it's no surprise to see them bagging a 2022 What Hi-Fi? Award as a result of their efforts.

The follow-up to the outstanding first-gen KEF LS50 Wireless speakers improves on greatness – no easy feat, even for an audio brand as surefooted as KEF.
Like their illustrious predecessors, the new LS50 Wireless II serve as a superb all-in-one system (streaming and amplification are built in) by dint of their advanced connectivity. Improvements include upgraded components and a new KEF Connect app where you can access the likes of Tidal, Qobuz, Amazon Music and Deezer. Not that you'll need to reach for any of the aforementioned apps; these speakers are capable of streaming via AirPlay 2, Google Chromecast and Bluetooth, and are also Roon Ready. You’ve also got an array of digital audio inputs – HDMI eARC, optical and coaxial – plus a 3.5mm aux input. Hi-res support extends to 24-bit/384kHz, MQA and DSD256 files, too.
KEF's striking design is matched by stunning sonics, enhanced by refreshed Uni-Q drivers and KEF's all-new MAT absorption technology. The presentation is spacious and the addition of the new MAT technology can be heard in the refined treble and clean mids. The whole presentation has been opened out, that extra room not only filled with subtler, more precise detail, but also allowing for greater instrument separation that makes its delivery sound much less congested in comparison.
Quite simply, if you're in the market for a high-fidelity all-in-one system packed with streaming smarts (and want a bigger sound than the smaller LSX II can deliver) this sophisticated sequel should be top of your list.

For KEF's 60th anniversary, the British company pulled out all the stops – it launched one of its most challenging products to date, the LS60 Wireless, a floorstanding sibling to its fantastic LS50 Wireless II all-in-one hi-fi system.
They're considerably slimmer than the standmount LS50 Wireless II, and house a new (12th) generation of KEF's Uni-Q driver – the smallest it's ever produced, in fact. There's also a tweeter gap damper and a new Z-Flex surround to aid dispersion and reduce distortion.
It all adds up to a phenomenal sonic package – producing possibly the finest audio we’ve heard from such a product so far. The LS60 Wireless kick out an immersive and focused stereo image with plenty of width and height, but that never sounds stretched. You'll struggle to believe such a weighty sound is coming from such slim towers.
Add to that a considerable feature set, including multiple streaming services, 24-bit/384kHz peak file support, DSD256 support and native app access, and you've got some of the best all-in-one speakers ever made in floorstander form.
