The KEF Q4 Meta On-Wall speaker is a versatile on-wall speaker that is ideal for left, centre, and right (LCR) speakers. Alternatively, use the wall-mount speaker as a surround for home cinema. Featuring a 5.25-inch 12th-generation Uni-Q driver array with MAT, the speaker delivers an immersive sound without using valuable floor space.
Metamaterial Absorption Technology (MAT)
The Q Series improves upon previous models by incorporating Metamaterial Absorption Technology (MAT). MAT is a highly complex maze-like structure that absorbs 99% of the unwanted noise from the driver’s rear, eliminating the resulting distortion and providing a purer, more natural sound.
Uni-Q Driver
The Q4 Meta On-wall speaker uses a 12th-generation Uni-Q driver array with MAT. Uni-Q acts as a single-point source to disperse sound evenly throughout the room. This allows everybody to enjoy the same natural, detailed sound for an immersive entertainment experience.
Refined Crossover
KEF designed a refined crossover for the Q4 Meta speaker, ensuring seamless integration of the speaker drivers. Over 1,000 specific measurements allow for a precise signal path and optimise the best possible performance.
One Speaker, Four Functions
Designed to be versatile, the Q4 Meta can be used in a left/centre/right (LCR) configuration or as a surround speaker.
Detail by Design
The Q Series speakers feature a contemporary minimalist design with a satin finish that offers a premium, subtle glow. Available in Satin Black, Satin White, and Walnut finishes, they blend effortlessly into any interior.
Magnetic Grilles
The speaker includes colour-matched grilles. The magnetic fixing provides a secure and precise fit, in keeping with the seamless styling of the Q4 Meta speaker.
