Features KEF’s patented Uni-Q driver array

The standards of architectural speakers have been reset forever. We introduce the in-wall KEF Ci5160REF-THX - the newest addition to THE REFERENCE family, meeting KEF’s standards for Extreme Theatre as well as THX Ultra Certification.

*Hand built to order, 2-3 week order time


The Ci5160REF-THX is engineered with a massive aluminium baffle to eliminate vibration and is the perfect platform for the 125mm (5 inch) MF/HF Uni-Q driver array with 25mm (1 inch) vented aluminium dome tweeter and four 160mm woofers.

Uni-Q driver array

At the heart of the Ci5160REF-THX is the 11th 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 160mm 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 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.
