REFERENCE 4c

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”) MF/HF Uni-Q driver array between four 165mm (6.5 inch) bass drivers, the Reference 4c reproduces every last detail exactly as the director or the artist intended - spatially precise, stunningly clear and with a dynamic range that takes rapid transitions in its stride. For movie buffs looking for total immersion, it’s the perfect centre.
