CompareREFERENCE 3
Same DNA, more modest dimensions – and the same uncanny ability to generate an intricate, totally natural-sounding 3D soundstage. The two 165mm (6.5 inch) bass drivers are positioned perfectly above and below KEF’s latest 125mm (5 inch) MF/HF Uni-Q driver array in a D’Appolito configuration. Fidelity across the midrange and treble is outstanding, and the transitions imperceptible. And with Uni-Q’s broad inclusive dispersion, everyone in the room can enjoy the same rich, spatially precise acoustic imagery without being restricted to a narrow sweet spot. As well as putting you right at the heart of the original performance, it gives you the soul.
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.
