Ci160.2QR Description

The Ci Series Ci 160.2QR is high-fidelity flush-mount loudspeaker utilising a fourth generation Uni-Q® driver array.

The driver array is mounted into a moulded ABS baffle and along with KEF's simple and ingenious screw down clamping system - with moisture-resistant fixings - allows placement even in the harshest environments such as bathrooms or even under eaves.

The bezel and stainless steel grille can be painted to specification or covered by fabric to suit the style of the room. The 2-way Ci 160.2QR combines 80W power handling and 89dB sensitivity, with a frequency response (±3dB) of 60Hz - 20kHz and a maximum output of 108dB.

Features and Benefits

Applications

The Ci Series Ci 160.2QR is best suited for high quality music and
