Technology & Innovation

The LS50 Wireless II isn’t just another set of powered speakers; it’s a complete high-resolution streaming system. At its heart lies KEF’s 12th-generation Uni-Q driver array, where the tweeter is positioned in the center of the mid-bass cone. This ensures that all frequencies originate from a single point, resulting in perfect phase alignment and remarkably lifelike imaging.

Behind the tweeter, KEF employs its Metamaterial Absorption Technology (MAT) — a revolutionary design that absorbs 99% of unwanted sound from the rear of the driver. The result is a cleaner, more detailed soundstage with incredible precision and reduced distortion.

Each speaker features two dedicated amplifiers — one for the tweeter and one for the mid-bass driver — delivering a combined power output of 380 watts per pair. This dual-amp configuration ensures dynamic headroom, fast transient response, and effortless control even at high volumes.

Connectivity & Smart Features

The LS50 Wireless II are designed for modern listeners who value convenience without compromise. They come equipped with HDMI eARC, optical and coaxial digital inputs, 3.5mm analogue input, and Wi-Fi/Bluetooth 5.0 for seamless wireless streaming.

You can stream music directly from Spotify Connect, Tidal, Qobuz, or Deezer, or use AirPlay 2, Chromecast built-in, and Roon Ready integration for high-resolution playback. The speakers also support up to 24-bit/384 kHz PCM and DSD256, ensuring uncompromised audio fidelity.

Everything is controlled via the KEF Connect App, which provides easy access to EQ settings, placement modes, and streaming options. You can adjust bass, treble, and subwoofer integration depending on your room acoustics — and once set, the system remembers your preferences automatically.

Voice-assistant compatibility adds another layer of ease, working seamlessly with Google Assistant, Alexa, and Apple HomeKit.

Performance & Sound Quality

When you press play, the LS50 Wireless II immediately justify their premium status. The sound signature is balanced, immersive, and breathtakingly clear. The Uni-Q driver ensures pinpoint imaging, so instruments and vocals appear precisely where they should — almost as if the performers are in the room.

The mid-range is where these speakers truly shine. Vocals sound rich, warm, and lifelike. Acoustic tracks have texture and emotion, while jazz and classical pieces reveal layers of subtle detail that lesser speakers simply miss.

The treble is crisp yet never harsh, delivering sparkle and air without fatigue. The MAT technology ensures that high frequencies stay clean and distortion-free, even during complex passages.

The bass is tight and controlled — impressive for the speaker’s size. While they won’t shake the walls like a floor-standing tower, the low-end response is deep and tuneful, reaching around 45 Hz with confidence. For most users, it’s more than enough; for those craving even deeper extension, adding KEF’s KC62 subwoofer integrates beautifully.

Overall, the sound is refined, open, and natural. The LS50 Wireless II handle everything — from delicate acoustic music to cinematic soundtracks — with authority and elegance.
