The Kef Ci1002Qs is the latest edition to the Kef Uni-Q custom installation speaker family, purpose built for direct flush mounting into ceilings or walls. Designed to smoothly integrate and architecturally match with existing ceiling fixtures, KEF’s trademark Uni-Q technology has a decisive performance advantage in these applications, because each point source driver array evenly disperses the sound, ensuring a smooth frequency response over a large area to create a spacious three-dimensional soundscape with genuine texture and depth. With a two-way Uni-Q driver of 100mm (4”), the Ci100QS is as satisfyingly musical to hear as it is neat in appearance.
The Ci1002qs delivers Hi-Fi quality sound through a low frequency driver with a high frequency driver mounted at the acoustic centre of the LF drive unit. The bezel and grill can be painted to match the interior decor of the room.
