Ci4100QL-THX is an in-wall speaker. A deep understanding of the film making process and surround sound is at the very heart of this speaker system. Together with the discreet bezel design, offering a slim visible rim around the speaker, this series gives you tremendous freedom to position the speakers where you please. The results? Action sequences are powerful, and dialog-driven moments are natural and engaging.

The stylish Ci200QL's thin bezel and narrow rim allow for flawless integration into your wall or ceiling. This product features KEF's amazing driver, which spreads sound over a wider area enabling you to use less speakers. These two features alone combine to make the Ci200QL perfect for any space. KEF's Ci loudspeaker design makes them so quick and easy to install that once the wire is run and the hole is cut in your wall or ceiling you can be listening to music in no time.

The in wall speaker delivers realistic and immersive sound with breath-taking dynamics for the most discerning music and movie lovers.
