KEF LS50 Wireless II
The All-In-One Wireless HiFi System That Actually Sounds Like HiFi
KEF LS50 Wireless II is one of those rare products that makes life simpler without sacrificing performance. It’s a fully active, high-resolution wireless speaker system with serious amplification, advanced DSP tuning, and the kind of imaging and clarity that made the LS50 name iconic in the first place.
This is the system for people who want true high-end sound without building a tower of boxes. Stream your music, plug in your TV, connect a turntable with a phono stage, add a subwoofer later, tune it to your room, and enjoy.
Why LS50 Wireless II Is a Best Seller
LS50 Wireless II solves the problem that most “wireless speakers” create: convenience first, sound second.
It combines KEF’s point-source driver technology, Metamaterial Absorption Technology, and powerful built-in amplification with modern streaming and real-world connectivity. The result is a system that works beautifully for music, and is genuinely brilliant for TV and cinema in a living room.
True Active Design, Real Power, Real Control
Each speaker contains dedicated amplification for each driver, with DSP controlling timing, crossover behaviour and protection. This gives you tighter bass control, cleaner dynamics, and more consistent performance than passive speakers paired with “whatever amp was on special”.
Amplification per speaker is rated at:
- 280W for the mid/bass driver (Class D)
- 100W for the tweeter (Class AB)
That’s serious power on tap, and it’s applied exactly where it’s needed.
Metamaterial Absorption Technology and Uni-Q
Clarity that stays clean at any volume
At the heart of LS50 Wireless II is KEF’s Uni-Q driver array, which places the tweeter in the acoustic centre of the mid/bass cone. This point-source approach helps sound arrive as a single coherent wavefront, improving imaging and making the listening position far less fussy.
Add Metamaterial Absorption Technology behind the tweeter, and unwanted high-frequency energy is absorbed to reduce distortion. You hear more detail, less edge, and a more natural sense of space.
Music Integrity Engine
DSP that serves the music, not the marketing
KEF’s Music Integrity Engine is the DSP brain that manages driver behaviour and timing. It’s what helps LS50 Wireless II sound tight, controlled and “together”, particularly when the music gets complex.
Benefits you actually notice:
- Cleaner separation between instruments
- More stable centre imaging
- Better bass definition and punch
- A bigger soundstage that doesn’t fall apart at higher levels
Streaming That’s Genuinely Modern
LS50 Wireless II is built around KEF’s wireless platform and works with a wide range of streaming methods and services.
Wireless streaming features include:
- AirPlay 2
- Google Cast
- Roon Ready
- UPnP compatibility
- Bluetooth
- Plays with Audirvāna
Streaming services supported via app and platform features include:
- Spotify (Spotify Connect)
- Tidal (Tidal Connect)
- Amazon Music
- Qobuz
- Deezer
- Internet Radio
- Podcasts
This means you can use it the simple way, straight from your phone, or the serious way, integrated into a full hi-res network system.
TV Ready, Living-Room Friendly
LS50 Wireless II includes HDMI eARC, making it a genuinely great TV system. You get clear dialogue, scale, and impact without needing an AV receiver in the chain.
For many homes, this becomes the ideal “music system that is also the best soundbar you’ve ever heard”.
Wired Inputs for Real Systems
Wireless is great. Options are better. LS50 Wireless II includes the connections you actually need to make it the hub of a modern system.
Primary speaker inputs include:
- HDMI eARC
- Optical (TOSLINK)
- Digital coaxial
- 3.5mm analogue auxiliary
- Ethernet (network)
- Ethernet (interspeaker)
Secondary speaker inputs include:
- Ethernet (interspeaker)
Outputs include:
- Subwoofer output on each speaker
Easy Setup, Multiroom, and Room Tuning
Setup is guided through the control app, and the system supports over-the-air updates.
You can connect the speakers:
- Wirelessly for a clean setup (all sources resampled to 96kHz/24bit PCM)
- Wired between speakers for higher interspeaker resolution (all sources resampled to 192kHz/24bit PCM)
For multiroom use, AirPlay 2, Google Cast and Roon can be used to stream to multiple compatible speakers around the home.
Room and placement tuning helps tailor performance to your space, which is essential for getting the best bass balance in real rooms.
Add a Subwoofer When You Want More Weight
LS50 Wireless II includes a subwoofer output on each speaker, making it easy to add one sub now or dual subs later. This is one of the best ways to upgrade the system for larger rooms or for people who want deeper bass for movies and electronic music.
