KEF Reference 3 Floorstanding Speakers



KEF Reference 3 Floorstanding Speakers

Mid-sized three-way floorstander

Reference 3 has the uncanny ability to generate an intricate, emotionally compelling three-dimensional soundstage that places you right at the heart of the original performance.

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.
