The Ci130QR In-Ceiling round thin bezel loudspeaker features KEF’s sophisticated ’sit anywhere’ Uni-Q driver array, which places the tweeter in the acoustic center of the bass/midrange cone. This allows both the tweeter and woofer to act as a single point source that disperses the sound widely and evenly throughout the room. Together with the discreet Ultra Thin Bezel (UTB) design, offering the slimmest possible visible rim around the speaker, the Ci130QR, part of our Q Series range of loudspeakers, gives you tremendous freedom to position the speakers where you please. The Ci130QR speaker features a 5.25in. Uni-Q Driver with 0.75in. aluminium dome tweeter.
