Information Sheet

KEF has taken a new style direction in custom installation with the Ci400 and the Ci400T.

Developed from the proven multi-awardwinning KHT2005, the innovative and stylish cast aluminium loudspeakers offer many advantages and benefits to the professional installer.

Using high-gradecrossover components in conjunction with theUni-Q® array contributes tohi-fisound quality across the full frequency range, making the product ideal for both foreground and background music.

Choose the Ci400 with its adjustable ball joint and you have flexibility in positioning. Use it on its own base, mounted horizontally or vertically on walls, on ceilings or, using the heavy duty mounting bracket, attached to poles.

Decide on the Ci400T and you have the additional transformer mounted within the base, providing an option for use with 70/100v line systems.

Commercial installations requiring hi-fiperformance will benefit from these stylish speakers.

Features and Benefits:

The 2-wayCi400 combines 50W power handling and 88dB sensitivity, for a maximum output of 104dB.
