The KEF Q4 Meta On-Wall Speaker is a high-performance, ultra-slim, two-way loudspeaker engineered to bring immersive, detailed sound into home cinema, stereo, or multi-channel setups without occupying valuable floor space. At its heart is KEF’s acclaimed 12th-generation Uni-Q driver array with Metamaterial Absorption Technology (MAT™), which positions the aluminium-dome tweeter within the mid/bass cone to act as a single coherent point source, significantly reducing distortion for pure and natural audio reproduction. Its slender on-wall enclosure, available in Satin Black, Satin White, or Walnut finishes, blends effortlessly with modern décor while offering versatile use as a left, centre, right, or surround speaker in home theatre systems. The precision-tuned bass reflex design and refined crossover network deliver clear dialogue, expansive soundstage, and controlled dynamics, making music, movies, and gaming sound more engaging and lifelike. With strong sensitivity, generous power handling, and wide frequency response, the Q4 Meta pairs seamlessly with quality amplifiers and other Q Series speakers to build a cohesive, high-fidelity audio experience.
