KEF CI200QL Ceiling Architectural Loudspeaker
Product Overview
The KEF Ci200QL is a premium high-performance speaker designed for in-ceiling and flush mount installations where a rectangular-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 25mm high frequency aluminium dome tweeter mounted in the acoustic centre of the 200mm 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 Ci200QL 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.
Key Features
- 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 lobing 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 115 degrees of coverage
- Weather Resistant – Manufactured using a proprietary plating and powder coating process, the KEF Ci200QL 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.

Frequently Asked Questions
One of the best suppliers of British hi-fi, KEF has a prestigious history dating back more than 50 years. Although there have been some ups and downs since then, it hasn’t lost its knack for creating elegant speakers with excellent sound.
95 percent of speakers are made to be listened to directly. A large dispersion reduces the necessity, although it is typically still the best option. If the speaker is bright, it is acceptable to forego toe-in, although doing so will degrade the imaging because each speaker’s hand-off will be more off-axis (the amount of degradation is speaker dependent).
You may connect the speaker system to your TV using the HDMI ARC on the KEF LSX II. The KEF LSX II can now be used as high-resolution TV speakers: Simply connect a wire from the HDMI ARC port on your TV to the LSX II’s newly installed HDMI ARC input.
We are a KEF service centre with authorization. When available, we fix KEF speakers using replacement parts straight from the manufacturer. When original parts are no longer readily available, we can still perform the majority of vintage repairs. For warranty and non-warranty repairs, we carry parts.
An array of high-end audio devices, including HiFi speakers, subwoofers, architecture speakers, wireless speakers, and headphones, are designed and manufactured by the British business KEF. It was established in 1961 by BBC engineer Raymond Cooke OBE in Maidstone, Kent (1925–1995).
As a result, for the best stereo sound, your speakers should be placed between six and twelve feet apart, with your preferred listening position being situated an equilateral triangle’s width away from the speakers.
The speakers can be turned ON or OFF using either the physical remote control or the KEF Control mobile app. To switch between ON and OFF on the physical remote control, push the power button once. Press the desired source on the KEF Control app in Standby to turn ON the speaker.
KEF Bluetooth wireless speakers let you enjoy HiFi sound wherever you are. These exquisitely designed speakers produce full-bandwidth audio, whether you’re looking for a small, portable speaker or want to improve the sound on your TV or PC.
However, since the majority of the crucial capabilities (TIDAL, Spotify Connect, and the KEF Control/Stream applications) depend on these, it is strongly advised that you connect the LSX to a home network with an active internet connection.
Unlike the passive KEF LS50, they are active powered speakers, which means each speaker has a built-in power amplifier. However, each LS50 Wireless speaker features a dedicated DAC (up to 24-bit/192kHz), DSP, and two amplifiers, one for the tweeter and one for the woofer.
In 1961, Raymond Cooke established KEF. He was an engineer with BBC training who later spent five years working for Gilbert Briggs at Wharfedale before going out on his own. The business has its headquarters in Tovil, Maidstone, and goes by the name Kent Engineering and Foundry.
RESET resets the LSX system to factory settings, removing network data included. The reset indication is above the reset button, which is located beneath it. Up until the RESET INDICATOR flashes, press and hold the RESET button. When the light stops blinking, the reset is finished.
The noises of a neighbouring speaker can be inconvenient and distracting if you live in an apartment or record in a noisy area. You can reduce the sound by muffleing your speaker with acoustic or polyurethane foam. Rags, cushions, tape, and plush animals can all be used.
A faulty audio connection connecting to the amplifier is one of the two main reasons of a constant humming or buzzing, or. Through an audio wire and into the amplifier, electrical noise is being sent.
Your speakers may be buzzing for a variety of reasons. The most frequent cause is when the bass or volume are pushed up too much, which puts a lot of strain on the speaker. Your speakers may begin to buzz as a result of a possible sound loop.
