Introduction
Thank you for purchasing this KEF Ci series custom installation loudspeaker.
These products have been designed for dry-lined, stud partition walls and

sound quality.
Warning
Installation should be performed by an installer who is skilled in the
proper use of hand and power tools, knowledge of local building and fire
codes, and who is familiar with the environment behind the wall or ceiling
where the speaker is being installed. No attempt should be made to install
these loudspeakers unless you are sure you will not be cutting through
electric cables, water or gas pipes, or supporting joists. Ensure the loading
on the wall or ceiling will support the weight of these assemblies.
