Kef Ci100QR Ceiling Speakers - Designed to smoothly integrate and architecturally match with existing downlighting sharing the same size bezel, 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 (4in.), the Ci100QR is as satisfyingly musical to hear as it is neat in appearance.

The 15cm deep detachable back-can supplied with the product, provides a sealed enclosure of 0.7 litres volume for optimum low frequency reproduction. Sprung fixing clips give flexibility of installation in ceilings and walls varying in thickness from 6mm to 30mm.

Kef Ci100QR Ceiling Speakers Key Features:
Purpose built for flush mounting into walls and ceilings.
Provides a compact solution to the problem of Hi-Fi quality sound from an in-wall/ceiling speaker,
Ci100QR consists of a polypropylene cone LF driver with the HF unit mounted at the acoustic centre of the LF unit. The bezel and grill can be painted to match the interior décor.
