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 (Connection) Possibilities
You can even receive internet radio stations and keep up with 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, so you can configure the LS50 Wireless II to your personal taste.
TECHNICAL DETAILS
As for physical technology, the LS50 Wireless II takes its lead from KEF's passive LS50 Meta speakers. Metamaterial Absorption Technology1 (MAT), a truly revolutionary tool 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 rear of the tweeter, eliminating the resulting distortion, and enabling a purer, more natural sound.
MAT & 13th Generation Uni-Q
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 rear of the driver to achieve a clean and pure sound.
Music Integrity Engine
The performance of the LS50 Wireless II is supported by KEF's bespoke Music Integrity Engine, an innovative collection of custom-designed digital signal processing algorithms optimized for the new Uni-Q with MAT driver array, enabling it to deliver perfectly tuned performance for better imaging and a tighter, untainted sound.
Amplifier Development
The LS50 Wireless II also offers plenty of power at the touch of a button. 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 meticulous amplifier development was carried out in-house by KEF to maintain full control over the quality of the performance delivered.
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 immersive.
The LS50 Wireless II is available in three matte finishes: Carbon Black, Titanium Grey, Mineral White, as well as 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 atop the new KEF S2 stands, which also feature integrated cable management and a stable pillar. The stands are color-matched to your desired LS50 Wireless II finish.
