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.
