The complete hi-fi system
Class-leading sound and style make the KEF LSX II wireless speaker system hard to beat. With AirPlay 2, Chromecast, wi-fi, Bluetooth and a wide range of inputs sockets, these wireless KEF speakers play everything you’ve got. Thanks to their 200 watt power output and the latest generation Uni-Q speaker system, they play it loud and clear, too.
The stereo advantage – made wireless
With two speakers rather than one, you get a much more immersive, three-dimensional sound. KEF’s Uni-Q speaker technology combines with their Music Integrity Engine for superb sonic precision, pinpoint accuracy and the least distortion possible. For music files up to 24-bit/48kHz, you don’t even have to physically link the speakers, making them wireless in every respect (a linking cable is supplied for listening to Hi-Res music files).
Made for High Resolution music – including support for MQA and ROON*
Designed for music lovers, the LSX II supports a wide range of High Resolution formats. With support for DSD and PCM music files up to 24-bit/384kHz, you get breathtaking detail and realism. MQA (Master Quality Authenticated) – as used by TIDAL Masters – is also compatible. ROON Endpoint status means it’s compatible with the award-winning music player – including Hi-Res files.
*ROON Ready expected via update late 2022.
Power to impress
Spreading an impressive 200 watts of power across the individual speakers, the LSX II have to oomph for effortless, room-filling sound. Carefully matched to get the very best from the speaker’s drivers, the amplifiers deliver smooth, punchy power that suits all types of music. If you’ve got a larger room or just want the ultimate bass, a subwoofer output lets you connect your choice of active sub.
Your music streaming, your way
Connect to your network via wi-fi or Ethernet and stream your music the way you want. Compatible with AirPlay 2 and Chromecast, the system suits most Apple and Android multi-room speaker systems. If you prefer to stream from your own music storage, UPnP (Universal Plug n’ Play) compatibility means it collaborates with a wide range of third party apps for effortless music network streaming.
Music streaming services and Internet Radio
Download the KEF Connect app (available for Android and Apple iOS) and enjoy easy access to all your favourite streaming services, Internet Radio and podcasts. Compatible with Spotify Connect (Premium account required), TIDAL, Amazon Music, Qobuz, Deezer and more, the app lets you access a near-limitless stream of music. The app also makes it easy to access your favourite Internet Radio stations and podcasts, all from one place.
For a quick and easy connection, these wireless KEF speakers are equipped with Bluetooth. The high quality Bluetooth 4.2 connection is perfect for quick and easy pairing with family and friend’s smartphones – making it an ideal way to share music.

Rated 5 out of 5 by P and E from Worthy of a Review Not being an audiophile, I invested in these particular KEF LSX 11 active speakers because of their size and wireless concept of listening to music with minimal clutter. The (Soundwave) model is also aesthetically very pleasing and would adorn most rooms. They are a solid, quality construction and were packed really well for delivery. I downloaded the KEF instruction manual prior to purchase and read it several times as they are quite an advancement for me and the information supplied in the box was reviewed as being minimal. Richer Sound Plymouth also arranged a demonstration for me prior to purchase. The KEF Connect App is an important component of the package that you will need. It is the key interface in setting up and controlling the speakers and I found it relatively easy to use and later preferred it to the supplied remote control, which works well but only has certain functions. Setting up is clearly explained if you follow the prompts and only takes a few minutes. I initially connected my turntable to the speakers via Bluetooth and the quality of sound was amazing. Wifi is also a feature that links to various streaming services (Tidal was available on a 90 day free trial) that deliver music seamlessly through the KEF App. KEF recommend using a 5GHz setting on your router if you get any problems with the 2.5Ghz dropping out (as it did several times) but converting my router was a doddle and a quick press of the re-set button on the speakers allowed me to select the 5GHz address and that has solved the issue. Tidal have some MQA audio music files but to take full advantage of them you might want to wire your two KEF speakers together with the supplied lead but the outcome is truly rewarding. The speakers also allow me to listen to my favourite radio station (which I can only get on the internet) using ‘Apple Air Play’ from my phone or iPad via the WiFi function. Out of curiosity, I also purchase a RCA to Aux cable to play my records as an alternative to Bluetooth. The quality of the sound is marginally better but both methods work seamlessly through the KEF App. I am also aware there are connections for the TV, CD Player, Computer and a Subwoofer but I have not yet used these but the evidence so far suggests the sound will be amazing as well. Are they worth the investment? Difficult to answer as we will all have different opinions and expectations. They are a small, powerful, quality speaker, extremely versatile, look fantastic and their output is truly outstanding and I am thankful for the help Richer Sounds Plymouth (Bradley, Josh and Jamie) provided in demonstrating and procuring these for me. I would not want to be without them.

Rated 5 out of 5 by The Grim from Buy them, try them, love them. I bought these a couple of weeks ago after demoing the original LSXs for a week. I love them. Super easy to set up, you can be listening to music 5 minutes out of the box. The sound quality is certainly a step up from previous small form factor speakers, i can feel the music through them. The seperation is great , nevermind for such small speakers. For me, they are speakers, hands down. If you plan to use these in a small room or on a desktop, you'll be overjoyed. If you have a bigger space, get the LS50w 2's. Do you need a sub with them? For me,I'm on the fence, for music, almost probably not, unless you really really care, for movies etc, maybe you like those explosions and what have you to shake the room. It's down to personal taste. Buy them, try them, love them.

Rated 5 out of 5 by Shildon Paul from Kef LSX 2 bought at Newcastle branch. A couple family members chipped in and gave me the money for some kef lsx that I had recommended to my father in law and loved them myself. The rumours were circulating that a new version was soon to be released so I held off. Even when they came out I wanted to see if it was worth the extra money over the originals so waited for the reviews etc. I phoned Richer Soumds in Newcastle and arranged a comparison with the Ls50 w2 having already had plenty listening to version 1 and both myself and Eughan were impressed with the improvements and surprised at the closeness in sound quality between the 2 so I kept in budget and plumped for the gold sound wave version. They are superb for my needs, smallish living room at fairly low volume. The soundstage is phenomenal and the detail they draw from my Tidal subscription is like listening to my favourite albums for the 1st time again. Vocals are presented forward with instruments all having their own pocket which makes for such a entertaining listen. I honestly don’t see the need for a sub but the option is always there. The app is well presented and Iv come across no glitches as yet. All I can say is try them, don’t be fooled by the small cabinets because they sound big! I love them and now don’t have that what if I get this amp or that streamer or those cables quandary anymore. Brilliant service and advice. Great speakers great store.
