KEF’s original LS50 Wireless speaker system made waves in the audio world and was a huge hit with our customers, offering impressive sonic fidelity in a convenient, self-powered package. The new LS50 Wireless II retains the sleek looks while making some important tweaks for even better performance. For starters, KEF has increased the built-in power, with 280 watts for each woofer and 100 watts for each tweeter.
Revolutionary sound absorption This speaker benefits from KEF’s new and innovative Metamaterial Absorption Technology (MAT). It’s a highly complex, mazelike structure that’s tuned to absorb unwanted sound coming from the rear of the tweeter. The resulting sound is clear, purer, and more detailed.
Wireless music streaming options These speakers are equipped with built-in dual-band Wi-Fi® and Bluetooth® 4.2 for easy music streaming. The free KEF Connect app offers access to popular music streaming apps, including Spotify® (via Spotify Connect), Tidal, Amazon Music, Qobuz, and Deezer. And internet radio and podcast listening is on tap as well.
