KEF Reference 4c Centre Channel Speaker



KEF Reference 4c Centre Channel Speaker

Three-way centre channel speaker

For movie lovers looking for total immersion, Reference 4c is the paradigm. For clarity, detail and emotional depth, it's a revelation.

Sound

As the main source of dialogue and vocals, the centre channel is critical to your enjoyment of what's on screen. With KEF's superlative new 125mm (5 inch) MF/HF Uni-Q driver array and four 165mm (6.5 inch) bass drivers, the Reference 4c reproduces every last detail exactly as the director or the artist intended.

A Class Apart

The Reference is the physical embodiment of KEF's Total System Design philosophy. Every component is optimised both within itself and as part of the whole, while every drive unit is given the chance to perform to the best of its considerable ability. The result is a loudspeaker that performs far beyond the sum of its parts.

Sound

Two 165mm (6.5 inch) bass drivers positioned above and below KEF's latest 125mm (5 inch) MF/HF Uni-Q driver array means that fidelity across the midrange and treble is outstanding. Everyone in the room can enjoy the same rich, spatially precise imagery and it puts them right at the heart of the original performance. 

Two drivers, a single point

At the heart of The Reference is the Uni-Q™ point source driver array. A state-of-the-art vented aluminium dome tweeter at the exact acoustic centre of a highly sophisticated midrange driver that delivers flawless natural sound across a wider listening area.
