FEATURES
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 inch) 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.
THE REFERENCE
The standard by which others are judged, and to which they aspire. The perfect reproduction of recorded sound is what KEF's legendary THE REFERENCE Series has always stood for. And after 40 years of continuous development, THE REFERENCE has earned its name as the yardstick of high-end acoustic engineering.
If you're a perfectionist when it comes to enjoying movies or music, it's the one name that towers above the rest. THE REFERENCE. It speaks for itself.
