KEF Reference 4 Meta
KEF centre speaker with four woofers and 12th generation Uni-Q with MAT, for precise home cinema and consistent listening throughout the room.
Description
The Reference 4 Meta is a centre speaker designed by KEF for high-end home cinema installations. It can also be used as a left, centre or right speaker, giving it a degree of versatility within a multichannel system. It belongs to the Reference range, positioned by KEF as the culmination of its sound reproduction expertise.
This speaker features four woofers paired with a 12th generation Uni-Q array incorporating MAT (Metamaterial Absorption Technology). MAT is based on a complex internal structure, comparable to a labyrinth, which absorbs 99% of unwanted sound generated behind the driver. This absorption limits the distortion typically produced by these stray waves and allows for a purer, more natural sound reproduction.
The Uni-Q driver functions as a single point source, promoting more even sound dispersion throughout the listening room. In practical terms, this reduces the 'sweet spot' effect: listeners positioned in different parts of the room perceive comparable sound quality, without needing to sit in a precise spot to enjoy optimal listening.
This centre speaker is aimed at home cinema enthusiasts and audiophiles seeking precise vocal and sound reproduction for dialogue and central effects in a multichannel installation. Its high-end design and manufacturing expertise make it a sensible choice for those seeking tonal consistency with other models in the Reference range.

What to check before buying used
The surrounds of the four woofers deserve careful visual inspection, as sagging or hardened foam indicates an example that has seen heavy use. The Uni-Q dome, positioned centrally on the baffle, should be checked both visually and by touch to rule out any signs of impact or deformation. The cabinet, often finished in gloss on this Reference range, readily reveals micro-scratches and chips along the edges, particularly around the metal inserts.
