KEF LS50 Wireless II pair of active speakers
On display in the Helsinki store!
The perfect all-in-one wireless speaker system.
No matter how you stream your music, the LS50 Wireless II is your choice. You can stream directly from the native Spotify app with Spotify Connect. With the KEF Connect app, you can also stream Tidal, Amazon Music, Qobuz and Deezer, or tune into internet radio and podcasts. AirPlay 2 and Google Chromecast support ensure you can easily get your favourite music playing. HDMI eARC connectivity means you can easily use it with your TV - no more needing two remote controls for TV audio.
KEF hasn't forgotten about audiophiles. The LS50 Wireless II speakers support streaming of 24-bit/384kHz music files. MQA, DSD256 and Roon Ready support will leave hi-fi enthusiasts in awe of the speakers' exceptional features and performance. Revolutionary metamaterial absorption technology eliminates distortion for a purer and more natural sound, while the 12th generation Uni-Q MAT driver delivers three-dimensional, wonderfully revealing sound in any room. The built-in amplifiers have also been revamped. The tweeter is driven by a 100W Class A/B amplifier, which produces smooth, incredibly detailed reproduction. A separate 280W Class D amplifier drives the midrange/bass driver. The speaker fills the room with controlled sound and up to 108dB of sound pressure.
The LS50 Wireless II is easy to set up thanks to the new KEF Connect app. It’s intuitive to use with any audio source in your home and allows for simple over-the-air firmware updates, bringing you new and improved features with minimal effort. The KEF Connect app lets you adjust intuitive sound settings to fine-tune the sound to your own taste. Simply select your favourite source to wake up the LS50 Wireless II and you’re instantly ready to enjoy your favourite music.
When you use the LS50 Wireless II with Airplay 2, Chromecast, or Roon, you can stream to multiple speakers in your home at the same time, making it easy to create a multi-room system that's simple yet powerful.
Every aspect of the LS50 Wireless II has been designed with acoustic benefits and design in mind. The low-diffraction, curved front panel is precisely modeled around the Uni-Q driver, while the striking heatsinks and color-matched reflex ports are located at the rear of the speaker. The control panel on top of the speaker is designed to be both stylish and functional.
