If you want a compact speaker system that delivers studio-grade clarity, premium aesthetics, and true all-in-one convenience, the KEF LS50 Wireless II stands among the very best. These powered bookshelf speakers merge advanced acoustic engineering with streaming-era versatility, letting you experience audiophile-quality sound without the clutter of separate amps or DACs.
In this detailed review, we’ll explore what makes the LS50 Wireless II a reference point for serious music lovers and why it continues to dominate the premium active speaker market.
- Available streaming services include: Spotify Connect, Tidal, Amazon Music, Qobuz, Deezer, QQ Music, Internet Radio, and Podcasts.
- Each speaker consists of a 280 watt amplifier for the mid range and 100w amplifier for the tweeter.
Design and Build Quality — Minimalist Luxury Meets Precision Engineering
The Carbon Black finish of the LS50 Wireless II oozes sophistication. Each speaker’s sculpted front baffle and curved edges minimize diffraction for cleaner dispersion, while the dense cabinet construction virtually eliminates unwanted resonance. Every element—down to the finely machined metal controls and acoustic ports—feels deliberate and premium.
KEF’s design philosophy blends form and function: these speakers look stunning in any space, yet every contour serves a sonic purpose. The result is a product that feels as refined as it sounds—perfect for both minimalist living rooms and serious listening rooms.
Cutting-Edge Technology — Acoustic Innovation Inside
At the heart of the LS50 Wireless II lies KEF’s legendary Uni-Q 12th-generation driver array, where the tweeter sits precisely in the acoustic center of the mid-bass cone. This concentric design ensures sound radiates uniformly, delivering impeccable imaging and a perfectly coherent soundstage.
The addition of Metamaterial Absorption Technology (MAT) revolutionizes the way internal sound waves are managed. MAT acts like an acoustic maze that absorbs unwanted frequencies from the back of the tweeter—reducing distortion and delivering stunningly pure highs.
Powering all this are dual amplifiers per speaker: a 280-watt class-D amp for the woofer and a 100-watt class-AB amp for the tweeter. Together, they ensure tight, dynamic bass and transparent midrange with breathtaking detail at any volume.
All-In-One System — Built-In Streaming, DAC, and High-Res Playback
The LS50 Wireless II isn’t just a pair of powered speakers—it’s an entire high-fidelity system. With built-in DACs, amplification, and streaming, there’s no need for separate components.
It supports virtually every modern connection:
- Wi-Fi and Ethernet for network streaming
- Bluetooth for instant wireless playback
- HDMI ARC for TV integration
- Optical, coaxial, and analog inputs for external devices
- Subwoofer output for system expansion
High-resolution playback is supported up to 24-bit/384 kHz PCM and DSD 256, meaning it’s ready for both casual streaming and critical Hi-Res listening.
KEF Connect App — Smart Control and Customization
Setup and control are handled through the KEF Connect app, which makes the process intuitive even for non-technical users. Once connected to Wi-Fi, you can stream music directly from Spotify, Tidal, Qobuz, Deezer, or local network storage.
The app also provides DSP-based adjustments for room placement and listening preferences. You can select whether the speakers are placed near walls or in open space, tailor bass extension, and fine-tune treble for your environment.
For serious listeners, this control over acoustic behavior is invaluable—it lets you shape your sound with precision without needing additional hardware or software.
Sound Performance — Immersive, Detailed, and Effortlessly Natural
The LS50 Wireless II’s sound signature is neutral, open, and incredibly detailed. These speakers project a wide, three-dimensional soundstage where every instrument and vocal sits in its own distinct space.
Bass and Dynamics
For their compact size, the low-end output is astonishingly tight and articulate. The powered woofers dig deep into the sub-50 Hz range, delivering punch and presence without muddying the mids. When paired with a subwoofer, the extension becomes cinema-grade—but even on their own, the bass feels clean, controlled, and musical.
Midrange and Vocals
KEF’s Uni-Q driver really shines in the midrange. Vocals sound warm and lifelike, acoustic instruments retain body and texture, and complex recordings maintain separation. The imaging precision means you can “see” the performers positioned in front of you.
Highs and Clarity
The tweeter’s integration with MAT delivers a silky, grain-free treble response. Cymbals shimmer naturally, strings glide smoothly, and subtle spatial cues become vivid. There’s no harshness—just refined, extended highs that make long listening sessions effortless.
Across Genres
Whether it’s jazz, EDM, classical, or cinematic soundtracks, the LS50 Wireless II adjusts gracefully. It’s revealing enough for audiophile recordings yet forgiving enough to make everyday listening enjoyable.
Movies, Gaming, and TV Use
With HDMI ARC, you can connect the LS50 Wireless II directly to your television for stunning two-channel sound. Dialogue clarity surpasses most soundbars, and the stereo imaging brings a new sense of realism to movies and shows.
Gamers benefit too—the low latency and precise directional cues make this setup excellent for immersive gameplay. It’s a versatile system that doubles as a premium entertainment hub while retaining its core identity as a world-class stereo system.
Everyday Usability — Streamlined and Reliable
The beauty of the LS50 Wireless II is in how seamlessly it fits into your routine. Once set up, you can play music instantly via your phone, TV, or voice-controlled assistants through AirPlay 2 and Chromecast.
Automatic source switching, volume memory, and firmware updates keep everything smooth and up to date. These quality-of-life details make it feel truly modern—no tinkering, just listening.
