This technology uses a labyrinth of channels to absorb 99% of unwanted high‑frequency energy from the back of the tweeter, delivering pure, natural treble. Combined with KEF’s 12th‑generation Uni‑Q driver array, it offers incredibly precise, three‑dimensional sound with a broad, evenly dispersed sweet spot.\u003c\/p\u003e \u003cp\u003eDesigned around a new platform, the LS50 Wireless II integrates powerful amplifiers—280 W Class D for the mid‑bass driver and 100 W Class A\/B for the tweeter—controlled by the Music Integrity Engine DSP for perfectly timed, controlled sound. Its new wireless architecture supports AirPlay 2, Google Chromecast, Roon Ready streaming and Bluetooth 4.2, while built‑in services let you access Spotify, Tidal, Amazon Music, Qobuz and more. With HDMI eARC, optical and coaxial digital inputs, analog auxiliary, Ethernet and RCA subwoofer output, it connects to everything from TVs to turntables.\u003c\/p\u003e \u003ch4\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eMetamaterial Absorption \u0026amp; Uni‑Q Driver\u003c\/strong\u003e: MAT technology absorbs 99% of unwanted high‑frequency sound from the rear of the tweeter, while the 12th‑generation Uni‑Q driver acts as a point source, delivering a detailed, immersive soundstage with reduced distortion.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePowerful Built‑in Amplification\u003c\/strong\u003e: Each speaker houses its own amplifiers: 280 W of Class D power driving the aluminium mid‑bass cone and a 100 W Class A\/B amplifier powering the vented aluminium dome tweeter, providing room‑filling dynamics with minimal distortion.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMusic Integrity Engine DSP\u003c\/strong\u003e: KEF’s bespoke Music Integrity Engine optimises the time alignment and frequency response of the drivers, ensuring tight, coherent bass, precise imaging and a seamless transition between the tweeter and mid‑bass driver.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eHigh‑Resolution Streaming \u0026amp; Services\u003c\/strong\u003e: Stream music up to 24‑bit\/384 kHz over your network, enjoy MQA and DSD playback and listen via AirPlay 2, Chromecast, Roon Ready, UPnP, Bluetooth 4.2 and built‑in services such as Spotify Connect, Tidal, Amazon Music, Qobuz and Deezer.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eComprehensive Connectivity\u003c\/strong\u003e: Inputs include HDMI eARC, TOSLINK optical, digital coaxial, 3.5 mm analog auxiliary, RJ45 Ethernet for network and interspeaker connection, plus subwoofer output.
