Product Features

The KEF Ci5160REF-THX is built to the same exacting standards as the KEF REFERENCE models. And like all REFERENCE speakers, the Ci5160REF-THX comes with the REFERENCE Build Certificate signed by the craftsman who built it.

KEF Ci5160REF-THX In-Wall Home Theater Speaker Uni-Q Driver Uni-Q Driver Array

At the heart of the Ci5160REF-THX is the 12th generation of the KEF’s signature innovation: the Uni-Q point source MF/HF driver array. With a 25mm vented aluminium dome tweeter at the exact acoustic centre of a 125mm mid-range driver, both act as a single source that floods the listening space evenly with a flawless natural sound field.
Bass Drivers

Like everything else about THE REFERENCE, the bespoke 165mm LF driver optimised for use in-wall, is a class apart. With a massive vented magnet assembly and a large aluminium wire voice coil driving an exceptionally light, stiff and strong alloy cone, the dynamics and power handling are superb.

KEF Ci5160REF-THX In-Wall Reference Home Theater Speaker Crossover Crossover

KEF engineers computer-modelled the ideal crossover networks before exhaustively auditioning every high-grade component to select those with the lowest distortion and the smoothest response. Perfectionism takes time, but the difference is clear. Nothing is overlooked – the HF and LF crossovers are even mounted on separate boards to minimise crosstalk.
