KEF are known for both quality and extravagance, especially with their MUON speakers, which are just completely bonkers. A pair of their more subtle speakers, the new LSX range has been released and we were fortunate enough to try them out. They retail for a cool £1000 and come in five different finishes, but how well will they perform? Let’s find out.

As just mentioned, this 2.0 speaker system comes in five different finishes, including black, gloss white, olive, blue and maroon. The speakers include a plastic front, rear and bottom, with a fabric wrap around the sides. Each speaker includes a 4.5″ woofer and a 0.75″ tweeter or also known as the Uni-Q driver array.

“By placing the tweeter at the centre of the midrange and bass cone, it radically improves stereo imaging. This not only makes music sound clear, detailed and lifelike, it does so across a wider listening area.”


Look & Feel

To the front of the speakers is a single indicator light, which changes colour depending on function. It also offers noise notifications too depending on the input being used. If you’re looking at the master speaker, you will find on the back, inputs such as an optical port, auxiliary jack, Bluetooth 4.2 with an aptX® codec, a mono port for a subwoofer, a USB port which allows you to charge your phone at 5V/2A, Ethernet In for network connectivity, a pairing button, Slave Out and Power. On the slave speaker is the ‘To Master’ Ethernet input, a pairing button and Power In. Yes, both of these speakers require 230v power, and two meter cables are provided but it’s worth baring in mind when positioning. The two speakers are connected together via a CAT6 cable, also provided or wireless when connected to your home network. Along with the speakers and cables, there is also a remote control in the box, along with instructions.


There is very little set up required and all you will need to do to get them going is simply link the two with the Ethernet cable provided and power them both. All the options and settings are detailed in the instructions if you need any help. For me, I initially used the Bluetooth feature, which I set up via the Bluetooth button to the rear of the master speaker, linked to my smartphone and started to listen to music. I also used the optical in option, plugging directly into my TV to try out some movies. The supplied remote control is handy, it’s easy to use and avoids the need for getting to the rear of the speakers once you’ve found a home for them.

The remote control comes with only minimal control which include things like power on and off, a source selector, volume up and down, a mute button and skip track.

Setting up the LSX speakers onto my wireless network was also an easy feat, and I was up and listening to Spotify in no time. The instruction manual gave extremely bland details on how to get this set up. Instead, it relied on the step-by-step guide provided by the KEF Control app. Following those was simple enough. It gave me a prompt to plug both speakers into power, and told me there would then be a amber/white flashing light. Once both speakers were flashing, the app asked me to open my WiFi settings on my phone to find the speakers there. To be honest though, the speakers in my setup would either be hardwired into my PC on my desk, or either side of my TV so a wireless setup wasn’t a priority for me.

At a glance, up close, anyway you look at these speakers, they look superb and ooze elegance. The attention to detail is very good and the overall footprint of the speakers is about right, not too overpowering on a side board or bookshelf, but also stand proud when in a room.



I’m not quite sure what to say for how they perform, other than it’s exceptional and a true pleasure to experience. I’ve tried a fair few speaker systems before, albeit sometimes on a cheaper scale and we’ve mainly experienced high end brands at trade shows, in custom made booths and yes they’ve sounded great but when you get them in your own space, with your own music, WOW. The quality of sound produced from these speakers blew my mind. Crisp, defined, pinpoint sounds, beautifully balanced with so much punch and liveliness, it gave me that fuzzy feeling inside and brought a smile to my face. I put on a variety of music, movie soundtracks that my children liked, bass-heavy tracks like Boasty by Wiley and then some of my favourite rock tracks, all of which sounded fantastic, the best I’ve ever heard them before.

In terms of their frequency range and response, it depends on how the speakers are set up. The frequency range which sits at -6dB is measured at 85dB/1m. There’s a More Bass Extension setting which will maximise the range up to 49Hz – 47kHz. Similarly with the frequency response, which sits at +3dB and the More Bass Extension setting sits between 54Hz – 28kHw.

When set up with my TV, I went straight to the first action movie I found on Netflix and skipped to a good bit. I was not disappointed. Crystal clear dialogue, yet booming thumps from explosions. I missed the surround sound but boy were these fun to use when watching movies.


The speakers are WiFi enabled, meaning you can connect them to your home network and via the KEF control app, you can push the latest firmware software to the speakers. They also have Spotify Connect & Tidal built in, plus DLNA compatibility, allowing access from a NAS drive at 48kHz/24-bit resolution. Hardwire the speakers into your network to gain an increased resolution of 96kHz/24bit. The speakers come complete with Apple AirPlay 2, allowing you to control multi room audio from your iPhone or iPad. There is a sub out option if you wanted to add a subwoofer, but they really don’t need it unless you’re planning on a big scale set up for a large space


The KEF LSX speakers are some of the best I’ve ever heard, they have been well designed, they’re packed full of tech and they should bring joy to any audiophile. They come in a variety of finishes and with a retail price of £1000, they are not cheap but worth every penny. I’m off to enjoy them some more, goodbye.
