The Reference One - Two

Reference Model One - Two

Model One~Two features a fourth generation Uni-Q twin driver array consisting of KEF's incredibly smooth, natural-sounding 25mm (1") ferrofluid-cooled soft dome tweeter at the centre of a 160mm (6.5") polypropylene cone mid-range driver.

Low - frequency extension is even more generous than you would expect, because the 160mm (6.5") bass driver is mounted inside the cabinet in its own dedicated 32-litre chamber, firing into the room via a large port in the mineral-filled baffle – subtly contoured, like the cabinet edges themselves, to minimise diffraction effects.

Of course there are still manufacturers who think people are impressed merely by the number of drivers on the front of the cabinet. But at KEF, we’ve learned over four decades that innovative engineering and impeccable craftsmanship are the way to deliver genuinely outstanding performance.
