A compact, advanced and complete active hi-fi system
The KEF LS50 Wireless II are active wireless speakers intended for those who want a high-level all-in-one system, able to combine compact design, built-in electronics, high-resolution streaming and a precise, engaging sound. This stereo system packs all of KEF's experience in acoustic design into a bookshelf format, offering an elegant solution for modern homes, refined living rooms and listening positions where real quality is sought without having to build a traditional hi-fi chain.
Advanced KEF technology for high-fidelity listening
The heart of the system is the celebrated Uni-Q driver with a 130 mm woofer/midwoofer and a 25 mm vented tweeter, paired with Metamaterial Absorption Technology (MAT) for cleaner, more controlled reproduction of the high frequencies. The LS50 Wireless II also feature dedicated amplification with a Class D stage for the low section and Class AB for the high range, delivering energy, control and detail from a system already perfectly optimised at the factory.
Streaming, connections and ease of use in a single system
The KEF LS50 Wireless II support music streaming up to 24 bit / 384 kHz, with declared compatibility with services such as Spotify Connect, Tidal, Amazon Music, Qobuz, Deezer and Internet Radio, and support for Roon Ready, as well as formats such as DSD and MQA. As for connections, they offer an extremely complete set with HDMI eARC, optical, coaxial and analogue inputs, network connections and subwoofer outputs, making them ideal both for music and for integration with the TV in a refined, contemporary home system.
