KEF Ci100QR Stereo

KEF manufactures high performance speakers for home cinema, hi-fi and installation applications.

Purpose-built for flush mounting, the Ci Series delivers KEF audio quality as unobtrusively as possible - and since all models are designed to withstand harsh environments such as bathrooms or even outside (under the eaves), there's virtually no limit to the design possibilities they open up.

Many models employ KEF’s exclusive Uni-Q technology to provide consistent sound coverage throughout the room that will greatly enhance your enjoyment of music or home cinema.

And with KEF's simple and ingenious mounting system, you'll also find them amazingly easy and rapid to install.

Purpose built for flush mounting into ceilings, the Ci100QR is the latest addition to the KEF UNI-Q® Installation speaker series.

Providing a compact solution to the problem of Hi-Fi quality sound from an in-ceiling speaker, the Ci100QR consists of a 100mm white polypropylene cone bass driver with a 19mm high frequency unit mounted at the acoustic centre of the bass driver.

The UNI-Q® drive unit is well renowned for its excellent dispersion characteristics, making the Ci100QR 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 varying in thickness from 6mm to 30mm.

To conform to architectural specifications, the bezel and grill can be painted to match the interior décor.

The Ci Series Ci 100QR consist of:
1 x 19mm aluminium dome tweeter
1 x 100mm white polypropylene cone with double neo compound magnet system

Please note that the mounting depth within our database indicates the minimum amount of space required for fitting, without using the supplied removable back-box. With the back-box in place, the minimum mounting depth of the Ci100QR is 145mm.

The bass response indicated is quoted as used with the back-box. Without the back-box the speaker will reach 80Hz.
