Seamless Smart Home Integration
The LS50 Wireless II is designed to enhance everyday life as much as deliver exceptional sound. Seamlessly integrate it into your smart home system to browse and play music, select sources, or use playback controls such as play, pause and volume adjustment directly via your smart home app or control interface — with compatibility for Elan, RTi, Crestron Home, Savant, Control4 and URC home automation systems.
Effortless Setup with the KEF Connect App
Beyond its flawless musical performance, the LS50 Wireless II is a breeze to set up thanks to the dedicated KEF Connect app. Intuitive to use with any source in your home, the app also enables simple over-the-air firmware updates that bring new and improved features with minimum fuss, alongside intuitive sound settings so you can tune the sound to your own personal taste. You can even select your favourite source to wake the LS50 Wireless II whenever it powers on, providing immediate access to the best sound without any extra steps.
Wired or Wireless Operation
You can choose to operate the LS50 Wireless II completely wirelessly at 24-bit/96kHz resolution for a completely clutter-free setup, or connect the two speakers using the supplied interspeaker cable for 24-bit/192kHz resolution sound — giving you the flexibility to choose between ultimate convenience and the highest possible resolution depending on your priorities.
Simple Multiroom System
When using the LS50 Wireless II with AirPlay 2, Google Cast or Roon, you can stream to multiple speakers around your home simultaneously. By using multiple pairs of LS50 Wireless II speakers throughout your home, you can build a simple yet genuinely high-performance multiroom system.
Metamaterial Absorption Technology & 12th Generation Uni-Q
At the heart of the LS50 Wireless II's exceptional sound is Metamaterial Absorption Technology (MAT) — a highly complex, maze-like structure that absorbs 99% of the unwanted sound radiating from the rear of the driver, eliminating the resulting distortion for a purer, more natural sound. Combined with the 12th generation Uni-Q driver array, the LS50 Wireless II delivers three-dimensional, wonderfully revealing sound from any position in the room — every spot truly becomes the sweet spot.
Music Integrity Engine
Every aspect of the LS50 Wireless II's performance is aided by KEF's bespoke Music Integrity Engine — a collection of DSP algorithms optimised specifically for the Uni-Q driver array, enabling a perfectly timed performance for better imaging and a tighter, more cohesive sound.
Plentiful Built-In Power
The LS50 Wireless II's amplification has been developed entirely in-house by KEF. Each tweeter is driven by a 100W Class AB amplifier delivering smooth, incredibly detailed treble performance, whilst dedicated 280W Class D amplifiers power the mid/bass drivers for room-filling, controlled sound up to 108dB maximum SPL.
Design
Every aspect of the LS50 Wireless II has been considered for both acoustic benefit and visual design. The low-diffraction curved baffle is precision modelled around the Uni-Q driver array, whilst eye-catching heat sinks and colour-matched ports feature on the well-equipped rear panel. A top-mounted control panel is both stylish and functional. The LS50 Wireless II is available in four matte finishes — Carbon Black, Mineral White, Sand Shell and Moss Green — with the colour mirrored across both the drive units and the rear-facing port for a cohesive, considered design throughout.
