KEF's Ci130CR In-Ceiling speaker includes a 130mm extended response bass driver and utilises a feature titled the "tangerine" waveguide, which has exceptionally wide dispersion characteristics and provides additional driver protection. The speaker's 'Tweeter' island offers a cleaner, more detailed and pure sound to as many listeners as possible - the tweeter island dramatically reduces diffraction and gives high-frequency response a large enhancement. 

KEF's vigorous research and development into a definitive and discrete Ci speaker have led to the production of the new Ultra Thin Bezel designs. These designs offer the slimmest visible rim around the speaker as is possible, to create a subtle and modern aesthetic. The speaker also utilises forward woofer mounting, which is another technology pioneered by KEF, that eradicates diffraction and make sure that the speaker performs to the same standard you'd expect of any KEF product, no matter where it's placed.
