Performance
Most accurate, immersive sound
LS50 Wireless II melts away, leaving you to enjoy the music. Revolutionary Metamaterial Absorption Technology eliminates distortion for a purer, more natural sound, while our 12th generation Uni-Q with MAT driver array delivers three-dimensional, wonderfully revealing sound anywhere in the room.
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.
