Each ‘path’ in the structure is a certain size and length and ‘tuned’ to absorb a specific range of frequencies. The application here takes the form of a round piece of plastic with a maze-like structure placed behind the tweeter. MAT helps to absorb soundwaves that radiate from the back of the tweeter dome so that they don’t interfere with the unit’s forward output. We first saw this MAT technology used on the KEF LS50 Meta passive speakers before it was introduced on the LS50 Wireless II. The tweeter also uses KEF’s Metamaterial Absorption Technology (MAT), a clever piece of engineering that we crowned 2020's Innovation of the Year at that year's What Hi-Fi? Awards. For this latest iteration of Uni-Q, KEF has added a tweeter gap damper and a new Z-Flex surround to aid dispersion and reduce distortion. It is in fact the smallest Uni-Q driver the company has ever designed and combines a 10cm aluminium cone for the midrange with a 19mm vented aluminium dome tweeter. It’s been designed specifically for the LS60 Wireless to cope with that change in width.
