Performance. Most Accurate, Immersive Sound.

LS50 Wireless II features KEF's 12th generation Uni-Q driver with Metamaterial Absorption Technology (MAT ™) for exceptional acoustic accuracy and a pure natural sound.

Music Integrity Engine

All aspects of the LS50 Wireless II’s performance is aided by KEF’s bespoke Music Integrity Engine. This collection of bespoke Digital Signal Processing algorithms is optimized for the Uni-Q driver, enabling it to deliver a perfectly timed performance, for better imaging and a tighter sound.

Plentiful Power

The built-in amplifiers have been developed in-house by KEF. Each tweeter is driven by a 100W class A/B amplifier that delivers a smooth, incredibly detailed treble performance. Dedicated 280W class D amplifiers power the mid/bass drivers, for room-filling, controlled sound up to 108db.

Every aspect of LS50 Wireless II has been considered for acoustic benefits and from a design perspective. The low-diffraction, curved baffle is precision modelled around the Uni-Q driver, while eye-catching heat sinks and color-matched ports are located on the well-equipped rear. The top-mounted control panel is designed to be stylish and functional.
