Description
LS50 Wireless II
The multi-award-winning LS50 Wireless music system set the bar high for high-quality wireless speakers, and in the same spirit of invention and innovation that created the first system, the LS50 Wireless II is much more than just a new generation.
The KEF LS50 Wireless II is a fully active Wi-Fi speaker system that delivers KEF's characteristic sound with intuitive ease of use and powerful streaming capabilities. Active electronics, digital signal processing, a new wireless streaming platform, and the new KEF Connect app work together to provide a first-class acoustic and user experience.
Absolute Freedom
New Wireless Platform
The new wireless platform, which forms the digital heart of the LS50 Wireless II, ensures that no matter how you want to listen to your music, you can do so with minimal effort and fantastic sound quality. With the LS50 Wireless II, you have direct access to your favorite music services, including Spotify (via Spotify Connect), Tidal, Amazon Music, Qobuz, and Deezer.
New (Connectivity) Options
You can even receive internet radio stations and get the latest podcasts via the KEF Connect app. AirPlay 2 and Google Chromecast seamlessly connect your compatible Apple or Android device and are even Roon-ready - ideal for multiroom music streaming throughout your home. Bluetooth further expands the options.
Via the HDMI, analog, optical, and coaxial inputs, there are also wired connections for your TV, turntable, CD player, and game console.
New App
The brand-new, standalone KEF Connect app guides you through system setup and control, including intuitive sound settings, allowing you to configure the LS50 Wireless II to your personal taste.
Technical Details
In terms of physical technology, the LS50 Wireless II takes its lead from KEF's passive LS50 Meta speakers. Metamaterial Absorption Technology1 (MAT), a truly revolutionary instrument in KEF's acoustic arsenal, is a highly complex labyrinthine structure where each of the intricate channels efficiently absorbs a specific frequency. When combined, the channels act like an acoustic black hole, absorbing 99% of the unwanted sound coming from the back of the tweeter, eliminating resulting distortions and allowing for a purer, more natural sound.
LS50 Wireless II uses a 13 cm Uni-Q driver array with Metamaterial Absorption Technology (MAT), which reduces 99% of the sound waves coming from the back of the driver for a clean and pure sound.
Music Integrity Engine
The performance of the LS50 Wireless II is supported by the bespoke KEF Music Integrity Engine, an innovative collection of custom digital signal processing algorithms optimized for the new Uni-Q with MAT driver array, allowing it to deliver perfectly timed performance for improved imaging and a tighter, uncolored sound.
Amplifier Development
The LS50 Wireless II also offers plenty of power at your fingertips. Each tweeter benefits from being driven by a new 100W Class A/B amplifier, delivering smooth, incredibly detailed high-frequency reproduction. Dedicated 280W Class D amplifiers drive the mid/woofers, providing room-filling, balanced sound. The careful amplifier development was carried out in-house by KEF to maintain full control over the quality of the performance offered.
DESIGN
The LS50 Wireless II features two subwoofer outputs, one on each speaker, for even more power and bass enhancement. In combination with KEF's KUBE series or the KF92 subwoofer, music and movies become even more impressive.
The LS50 Wireless II is available in three matte finishes: Carbon Black, Titanium Gray, Mineral White, and a Crimson Red Special Edition.
Matching Stands
On the underside of the LS50 Wireless II, each corner point has a threaded insert allowing the speaker to be secured on top of the new KEF S2 stands, which also feature integrated cable management and a sturdy column. The stands are perfectly color-matched to your desired LS50 Wireless II finish.
