WARNING:
From the manufacturer
The convenience and connectivity of wireless. The emotion and detail of true high-resolution stereo. And all from a compact system designed to fit almost anywhere. LSX is the speaker system for the way we listen today.
Colours and fabrics.
Whatever your style, there’s an LSX to match. The system comes with a choice of five colours, and is clad in an industrial fabric by Danish contemporary textile designer, Kvadrat. These fine details make the LSX pleasing to the touch, as well as appealing to the eye.
Uni-Q. The sweet spot just got a lot wider.
LSX comes with KEF’s breakthrough 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.
Features:
- LF: 70W/HF: 30W Per Speaker
- Resolution up to 192kHz/24bit
- Apple AirPlay 2
- Spotify & TIDAL Streaming
- Bluetooth
- Roon Tested
- Optical Input and Analog Inputs
- Subwoofer Output
Play anything. Hear everything.
From streaming to gaming, from TV to multi-room music, LSX is designed for all your home entertainment needs. Play what you like, how you like, where you like and experience it all in glorious high-resolution stereo.
Contoured baffle. Hear the music, not the speaker.
Optimised using Finite Element Analysis, LSX’s contoured baffle improves sound dispersion, ensuring that sound waves travel outwards and are not reflected around the cabinet surface. The result? A purer sound, with less cabinet colouration.

There was a problem filtering reviews right now. Please try again later.
Speaking of selection, it appears that almost all the negative reviews around this system relate to difficulty people have with either connecting it to streaming or some other aspect of its streaming software – not with the audio quality of the speakers – which are simply phenomenal. I think you'd be hard-pressed to find small pair of speakers that sound as good, and outside of KEF's own LS50 systems (powered or otherwise), in my opinion, there isn't one.
It's not perfect however, and I would dock KEF for their failure to duplicate at least the basics of the control architecture of the remote on the back panel of the master speaker – this leaves you with an inability to turn the system out of its suspended or sleep mode without the remote control. If you lose your remote control or it becomes inoperative (which is going to happen to more than a few users, given how often this system is likely to be placed outdoors on patios and lanais and thereby potentially exposed to moisture at least accidentally), you cannot either turn the system on from suspend, or adjust volume, except through your Bluetooth source. Re-initializing the system by unplugging it still brings the system up in a suspended mode. We may attempt to secure a second remote control from KEF. Also one has to admit to the somewhat buggy nature of some of their apps. However, since we drive the speakers exclusively from a Bluetooth source streaming lossless files, potentially buggy interactions with streaming software are a nonissue.
Pros:
1) Superb tonal balance and neutrality, including remarkable fidelity on vocal material, consistent with virtually all of KEF's recent high-end designs
2) excellent bass, given small cabinet size and one half cost of state-of-the-art LS 50 powered system
3) with decent subwoofer the LSX becomes relatively inexpensive full range system with very small footprint
4) attractive range of colors to match room interiors (plus the white color no longer contains a hideous copper driver seen in LS 50)
Cons:
1) you're SOL if you lose the remote or it becomes nonfunctional
2) Streaming app can be a chore to get operating properly
3) not much else to complain about
In summary, it's a nearly perfect small compact system for small to medium-size rooms and spaces, it will play decently loud, and it is an exceptionally faithful and accurate transducer. If you've got a high quality source, it can approach a state-of-the-art system for way less than state-of-the-art money, especially with the addition of a decent subwoofer.
– They have no physical control buttons for on / off / volume so most settings must be controlled by the app.
– The app simply doesn't work. It doesn't connect to the speakers. It doesn't connect properly to the network. My partner and I are both pretty technical and even after going into IP settings and hard wiring the speaker to the router to get it set up, it drops back out soon as the speaker goes on stand by.
– As stated, I simply want to use these plugged into my computer. Sounds simple right? No. The speakers put themselves on stand-by whenever idle, thus losing communication with both the computer and app. How do you turn off stand-by mode? With the app that won't re-connect every time they're powered off. It's a chicken and egg situation. So every time I turn on my computer, I also need to turn these on with the remote and tell them every time which input selection the computer is on. It's frustrating and unnecessarily convoluted.
So even as someone willing to forgo all of the wireless features these come with (I'd love Airplay, but even that lasted 5 seconds before the app crashed, the speakers forgot who they were and what they were supposed to do) I still found these almost completely useless for daily use. Super disappointing considering coming into the purchase a fan of KEF and willing to miss out on features to plug them into my mac. KEF, if you're going to make a product that is completely reliant on an app, you need to make the app actually work.
The one star they get is for their outstanding sound quality and clarity. Pity it takes a technician, patience and whole bunch of time wasting to hear them.

NB: This review is based on KEF LSX running latest version of both Firmware and the app. It amazes me that app development and firmware this bad be A: Be released in 2021, and B: Make it past quality control and into customers hands.
I have this in a 12 x 10 ft bedroom and it seems just about perfect for this use-case. I don't know if I would use it in a near-field setup, nor do I think I would use it in a room larger than say 15 * 15. To me this really is the perfect bedroom/study type audio system. I also have the LS50W in my living area, about 15 * 30... and those leave me wanting in such a comparatively large space (they worked much better in a 12*15 living room I had them in previously).
To my ears, the LS50Ws are very close to the LSX, and going with one or the other really should come down to the room size they're in.
Top reviews from other countries
Non si può tacere il fatto che si tratta di diffusori amplificati e connessi, ovvero già pronti per garantire la fruizione dei principali servizi di streaming musicale (Tidal in particolare), perciò ci troviamo di fronte ad un sistema completo: diffusori, biamplificazione con DSP, DAC e Streamer audio. Proprio quest'ultima funzione delle LSX lascia molto a desiderare, almeno quando si voglia o si debba usare l'applicazione nativa della KEF, KEF Stream. Quest'ultima è veramente irritante: nello streaming da Tidal oppure da libreria locale ha la tendenza a saltare un brano su due nella riproduzione di un album e, molte volte, interrompe per alcuni secondi la riproduzione stessa (da Tidal).
Questo fatto mi impone di giudicare negativamente il prodotto e mi ha imposto l'effettuazione del reso.
Anche il prezzo al quale vengono proposte mi pare esagerato.
Auf Grund unserer Wohnungseinrichtung habe ich mich für das weiße Modell entschieden, diese sind als einzige dieser Reihe aus hochwertigem Kunststoff. Die Verarbeitung ist wie ich es für ein Produkt dieser Preisklasse erwarte absolut top und hier gibt es nichts zu meckern.
Das richtige Aufstellen der Lautsprecher ist kinderleicht und in der leider nur englisch verfügbaren Beschreibung genauestens beschrieben. Damit ich die Lautsprecher mit meiner Stereoanlage betreiben kann, habe ich diese mit dem AUX Kabel verbunden. Ein weiterer Anschluss kann mit dem vorhandenen Sub Woofer verbunden werden.
Der Sound der anschließend aus diesen kleinen Lautsprechern kam, war einfach nur überwältigend. Klare Höhen, tiefer angenehmer Bass und toller Sound, man hat gar nicht gemerkt das ich eine Schallplatte angespielt habe. Das Verbinden der Lautsprecher per Bluetooth ist ganz schnell und unkompliziert und mit jedem Gerät durchführbar.
Um die beiden Schmuckstücke optimal und vollumfänglich nutzen zu können, kann man diese noch per LAN oder Wifi mit dem heimischen Netzwerk verbinden. Dieser Prozess gestaltete sich leider etwas komplizierter und war mir nur Dank eines deutschsprachigen Videos möglich. Die passende App erlaubt eine genauere Einstellung der beiden Boxen und anhand der App kann auch auf die einzelnen Anschlüsse umgeswitched werden, was auch mit der mitgelieferten Fernbedienung möglich ist.
Was ich persönlich Klasse finde, ist das man die Lautsprecher einfach transportieren kann und dadurch auch im Garten oder sonst genutzt werden können.
Fazit: Hochwertige Lautsprecher zur Aufrüstung der heimischen HiFi-Anlage, des Fernsehers oder einfach zum Abspielen per Bluetooth. Für Musikliebhaber absolut empfehlenswert

Looks 10/10

Everything else 0/10
I will never buy another KEF product again, even though they sound GREAT and look SUPER sexy, the best speakers for a PC desktop. Principal of the issue is that, these speakers are so gimped they are no different than hardwired speakers. Also, no, it doesn't look like anything has been done, or will be done by KEF, so look for a different brand who actually cares about your money and their products.
