Immersive, Accurate Sound Performance

Metamaterial Absorption Technology (MAT™)

MAT™ absorbs 99% of unwanted sound from the rear of the driver, dramatically reducing distortion. The result is purer treble, improved clarity and more natural tonal balance.

12th Generation Uni-Q® with MAT™

The Uni-Q driver array positions the tweeter at the acoustic centre of the mid/bass cone, creating a true point-source design. This expands the sweet spot and delivers consistent, three-dimensional sound throughout the room.

Music Integrity Engine

KEF’s bespoke Music Integrity Engine uses advanced digital signal processing to optimise timing, phase and driver performance. The outcome is tighter bass, precise imaging and a rich, full-bodied soundstage.

Powerful Built-In Amplification

Each speaker features dedicated amplification designed in-house by KEF:

• 100W Class A/B amplifier for the tweeter

• 280W Class D amplifier for the mid/bass driver

• Maximum sound pressure level: 108dB

This configuration ensures controlled, room-filling performance with exceptional detail and dynamic range.

Smart, User-Centred Control

The KEF Connect app makes setup simple and intuitive. It provides:

• Personalised EQ and sound tuning

• Source selection preferences

• Room placement optimisation

• Over-the-air firmware updates

You can also integrate the LS50 Wireless II into your smart home system to control playback, adjust volume and switch sources directly from compatible apps or voice interfaces.

Simple Multiroom Audio

Using AirPlay 2, Google Cast or Roon, you can synchronise multiple compatible speakers throughout your home. Create a high-performance multiroom audio system with ease, whether using multiple LS50 Wireless II pairs or combining them with other compatible devices.

Every detail of the LS50 Wireless II cabinet is engineered for both performance and aesthetics:
