Product Description

KEF Ci100QS is a square ceiling speaker, featuring patented Uni-Q drivers with a design that makes it easy to install. Ci100QS provides a remarkable sound and integrates seamlessly with a wide variety of electronics.


Providing a compact solution to the problem of Hi-Fi quality sound from an in-wall/ceiling speaker, the Ci100QS consists of a 100mm polypropylene cone LF driver with the 19mm HF unit mounted at the acoustic centre of the LF unit. The bezel and grill can be painted to match the interior décor.

Trademark Uni-Q

Well renowned for exceptional sound distribution, Uni-Q makes the Ci100QS perfect for installation in non-uniform environments, without compromising the reproduction across the listening area. 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.

This gives a great advantage for in-ceiling mounting applications, because each point source evenly disperses the sound, ensuring a smooth frequency response over a large area for a broad 3D soundscape with genuine texture and depth.


The Ci Series Ci100QS is best suited for high-quality music and speech reinforcement applications requiring hi-fi performance such as:

- Multi Room systems.
- Home Theatre systems.
- Lounges, Bars, Boutiques.
- Boardrooms & Offices.
- Airports, Convention Centres, Hotels.
- Live Theatre/Concert Hall fill-in.
- Houses of Worship.
- Sports Arenas.
