But making great loudspeakers is an art as much as a science, and these innovations are all designed to enrich that emotional experience by achieving the clearest, purest sound. Welcome to the world of KEF Reference Series. VISIONARY...

In a world where everything is relative, KEF Reference Series has always stood for absolute standards. The design approach has always been consistent: to give some of the world’s most gifted acoustics engineers the freedom to set a new performance yardstick.

As KEF’s signature technology, the Uni-Q concept is renowned for its uncannily natural sound and stable imaging. In the Uni-Q configuration the tweeter is mounted at the centre of the midrange cone so that their acoustic centres are at the same point in space.

Interesting things can happen when you push beyond normal limits. Senior Acoustics Engineer, Dr. Andrew Watson and the Reference Series design team set out to build the most natural sounding loudspeakers possible, irrespective of cost or practical constraints. The ‘Austin’ concept was the result – a technological tour de force standing two metres high and weighing more than 120 kilos apiece.

The new Reference Series responds even more musically than its acclaimed predecessors by combining design innovation with an exceptionally rigorous approach to the specification of each component. The crossovers, for example, are computer-modelled to optimise amplitude and phase behaviour for the smoothest possible integration.

KEF Reference Series cabinets are works of art in themselves, quite apart from all the high-end technology they enclose. It’s not just the sumptuous choice of finishes (although the silky pale Satin Sycamore and the sheer depth of the High Gloss Cherry, American Walnut and Piano Black finishes do admittedly hint at the uncompromised build quality).
Page 8
The exceptional finish speaks for itself, but the same obsessive attention to detail applies to the parts you never see. KEF’s own graded OFC (Oxygen Free Copper) cable is soldered by hand and the drivers are magnetically shielded to prevent interference with your TV.

In a word, bliss. As KEF’s flagship loudspeaker, every inch of Model 207/2 is designed to make what you hear sound totally real. This is where all the latest KEF technology breakthroughs find their finest expression; sound quality, bandwidth and dynamics are second to none.

In any acoustically correct listening environment, audio monitor fidelity is paramount. And after auditioning major high-end brands,Trutone found that KEF Reference Model 207 consistently reproduced the most faithful sound. According to chief mastering engineer Carl Rowatti, “Sound quality is our business, so our audio systems have to perform equally well across every type of music from hip hop to classical.

A giant among full bandwidth floorstanders. Whether you prefer Stradivarius or Stratocaster, Model 205/2 is a sublimely musical performer when it comes to conveying the nuances of recorded sound. The new Uni-Q array is so perfectly attuned to reproducing the human voice that vocals acquire previously unheard-of definition.
Page 13
Of course they’re continually seeking efficiency gains to control cost without compromising quality. But above all, it’s their talent that sets KEF apart – that, and taking the trouble to find out exactly what our customers want.

The three-way bass reflex Model 203/2 shares the technical virtuosity that makes the larger floorstanders great, but in a more compact package – the same new generation KEF technologies, the same carefully chosen high quality components and the same unrivalled build quality.

Like the movement of a precision chronometer, Model 201/2 proves that engineering excellence has nothing to do with size. A three-way bass reflex design, Model 201/2 packs all the benefits of the latest Reference Series technology into an elegantly compact cabinet. The same sensational new Uni-Q array, with its lightweight neodymium magnet assembly, braced compound tweeter dome and...

Ezaki and his team duly set about remastering for KEF a 2001 performance of the Bach Toccata and Fugue in D minor by the celebrated Czech organist Ales Bárta. The result is a five-channel SACD (Super Audio Compact Disc) direct stream digital recording of breathtaking clarity and finesse.

Movie stars don’t come more charismatic than this; expansive, engrossing and disarmingly natural. Together with breathtaking sonic accuracy and spatial precision, these are the qualities a great centre channel loudspeaker aspires to – and the pleasingly slim Model 204/2c has them all. No wonder.

The same enhanced point source effect. The same broad, even dispersion characteristics. The same essential truthfulness. The three-way bass reflex Model 202/2c has all the acoustic virtuosity of the 204/2c, but with a single 165mm (6.5in.) bass driver on each side of the mechanically decoupled Uni-Q array.

Dolby-certified dubbing theatres fully equipped for modern digital post production. Their studio midfield loudspeaker of choice? KEF Reference Series, naturally. “Anvil has always sought to push the envelope of audio convention,” says Rupert Scrivener of Technicolor, “and that means insisting on the best technology.

For creating cinema-quality surround sound effects, there’s no substitute for the right high-end dipole loudspeaker. And with the new 165mm (6.5in.) Uni-Q point source drivers alongside KEF’s ultra-low distortion 200mm (8in.) bass driver, the three-way closed box Model 206/2ds is just that.
Page 24
(18in.) cone of the new Model 209 drive unit has a linear excursion of no less than 60mm. This is only possible by combining KEF’s ingenious double suspension system and critically designed large roll surround with a new double radial array of neodymium magnets powerful enough to create a constant 80mm long magnetic field.
