KEF Ci100QS In-Wall Speaker

KEF Ci100QS In-Wall Speaker with Uni-Q® Driver Array

The compact KEF Ci100QS is a premium high performance speaker designed for flush mount installations where a square shaped assembly is preferred. It’s a coincident point source design featuring KEF’s proprietary “sit-anywhere” Uni-Q® technology with a driver array that includes a 0.75” (19mm) high frequency aluminium dome tweeter mounted in the acoustic centre of the 4” (102mm) low frequency woofer. The tweeter features KEF’s Tangerine Waveguide engineered to enhance high frequency dispersion and when combined with the Uni-Q array, creates a speaker that delivers exceptionally smooth and consistent coverage across a wide listening area.

The KEF Ci100QS is constructed using weather resistant components and the Ultra-Thin Bezel and Grille are treated with a UV protective finish making this speaker ideal for hi-fidelity applications in premium commercial venues such as luxury hotels, conference centres, and restaurants.

KEF “Sit-Anywhere” Uni-Q® Technology

This proprietary driver array places the tweeter in the acoustic centre of the woofer delivering wide dispersion with consistent sound characteristics throughout the space. Because the high and low frequencies originate from the same point, acoustic lobbing problems common to other speaker designs are virtually eliminated allowing fewer speakers to deliver smooth coverage across a wide listening area.

Tangerine Waveguide

In addition to protecting the driver, the Tangerine Waveguide further enhances dispersion allowing for 150 degrees of coverage.

Weather Resistant

Manufactured using a proprietary plating and powder coating process, the KEF Ci100QS is UV protected and designed to withstand the harshest operating environments.

Ultra-Thin Bezel (UTB)

To maintain a premium aesthetic appearance, the ABS bezel was carefully engineered to be as thin as possible while maintaining the necessary structural rigidity.

Magnetic Grille

For security and ease of installation the grille attaches by a powerful magnetic circuit and can be painted to match any décor.

IP64 Certification

The speaker passed official IEC testing to ensure that splashing water would have no harmful effects on assembly components.

Our Review

The compact KEF Ci100QS may be small in size, but it delivers impressively rich, room-filling sound that belies its footprint. Designed for discreet flush-mount installations, it blends seamlessly into any space while delivering the kind of refined clarity KEF is known for. At its heart is KEF’s ingenious “sit-anywhere” Uni-Q® driver array, where the tweeter sits perfectly in the centre of the woofer for remarkably even sound dispersion and a beautifully natural tone no matter where you’re listening from. The Tangerine Waveguide further enhances high-frequency performance, creating smooth, detailed audio that feels effortlessly balanced. Built tough with weather-resistant materials, UV protection, and an ultra-thin magnetic grille, the Ci100QS is equally at home in luxury hotels, stylish restaurants, or high-end homes - an elegant blend of smart engineering and understated performance.
