KEF Audio Loudspeaker User Manual

FULL LINE CATALOGUE
People who know sound,know KEF. It’s a name that commands such respect because we’ve never been a ‘me too’ manufacturer. Ever since the early days of hi-fi, our approach has been driven by a passionate belief in the power of new materials, new technologies and design ingenuity to heighten the enjoyment of recorded sound. This is as true today as it was back in ’61,when KEF was founded by Raymond Cooke, which is why KEF speakers have ranked among the finest in the world in every decade since. In that time, KEF has pioneered many landmark innovations. New diaphragm materials. Neoprene damping. The use of computer modelling in research and quality control. Digital testing to unprecedented tolerances. Total system design methods. Conjugate load network techniques. And arguably the greatest breakthrough of all: the UNI-Q
®
array,
based on technology originally developed for the NASA space programme and protected by world wide patents. No other manufacturer has done more to advance the principles of loudspeaker engineering,and none is better placed to exploit the potential of the latest digital formats.
Separating out the mid-range and high frequency drivers into their own pods has long been a KEF tradition dating all the way back to 1977 with the worlds first speaker
to do this, the Model 105. This technology lives on today in the Model 207 flagship.
KEF - THE FACTS AND THE FEELING

POD TECHNOLOGY
The continuing evolution of KEF’s legendary Reference Series has always been based on the concept of benchmark precision. Every time a new generation of models is developed to incorporate more sophisticated technologies,w e build pr ototypes that are as close to perfection as possible.These then become the ‘Reference’ to which every single production version must conform,each set assembled by a skilled craftsman who matches their performance to a tolerance of just 0.5dB. As the latest incarnation of this approach, the Reference Series is a quantum leap forward in audiophile quality sound. In fact, its performance envelope extends well beyond the range of human hearing. This is not as futile as it may at first sound - whereas con ventional CDs carry no audio information beyond 20kHz, extended bandwidth formats such as SACD and DVD Audio contain signals up to 40kHz and more. Consider the analogy that even though no-one drives at 200 mph, cars that are engineered to do so are inherently better performers at lower speeds.
That’s why all new Reference series models come
with a state of the art 19mm (
3
/4”) titanium
dome Hypertweeter
TM
for massively extended HF performance. Mounted in low diffraction, chrome-plated steel enclosures
time aligned with the main array,they deliv er
flat response to 55kHz and useful energy up to
80kHz.What you hear is a sweeter,more natural sound.
Radical new UNI-Q
®
driver arrays - the ultimate r efinement of KEF’s trademark technology - where the tweeter is mounted at the acoustic centre of the midrange cone ­provide an immaculate single point source, the Holy Grail of loudspeaker design. With the midrange cone and surround integrated into a single Uni-Form moulding, there are no discontinuities to distort the HF energy from the 25mm (1”) elliptical profile titanium dome tweeter. With only midrange frequencies to handle, movement of the UNI-Q cone is so modest that virtually no distortion is caused by intermodulation with the tweeter. Like the bass drivers, an open chassis design - minimises acoustic reflection behind the cone.
The result is an even more spacious, better defined sound stage over a very large area,with exceptional off-axis r esponse and none of the ‘sweet spot’ limitations of conventional speakers. Bass extension is equally stunning, thanks to ultra-low distortion motor systems and high tech reinforced diaphragms. And with each bass driver radiating directly from its own separate internal enclosure to avoid the distorting effects of vertical standing wa v es that tall cabinets usually suffer from, you experience noticeably clearer,more open bass. As you would expect from a handmade KEF product,
build quality is as outstanding as the
specification of each individual component.
Carefully graded and soldered by hand,
KEF’s own oxygen-free copper cable
ensures the best possible signal
transmission, with terminals machined
from solid brass and plated in gold. High order crossovers with advanced air-cored inductors and polypropylene capacitors ensure faultlessly smooth integration. For optimum performance in real rooms, all models accommodate tri-wiring and are fitted with a boundary control device to adjust bass response according to speaker positioning and the acoustics of the listening area. Magnetic shielding ensures trouble-free positioning in home theatre applications.
Engineered from laminated birch ply using KEF’s own internal bracing system, the new curved section cabinets are elegantly profiled to minimise coloration and finished in a choice of hand-matched hardwood veneers. More than ever before, these are very special speakers indeed.

Model 207
A true five-way design, the 207 is instantly recognisable by the cast aluminium pod, which is shaped to damp the internal sound field of KEF’s new generation UNI-Q
®
upper midrange driver. Beneath the state-of-the-art elliptical profile titanium HypertweeterTM,a bonded Uni-Form cone/surround provides the optimum waveguide for the 25mm (1”) titanium dome HF unit leading to exceptional vocal clarity. The lower midrange driver is derived from the LF unit, KEF’s lightweight neodymium magnet assembly allowing it to
be effectively decoupled from the cabinet to improve imaging and integration while minimising coloration. Both long-throw 250mm (10”) bass drivers have their own dedicated enclosures, tuned to different frequencies for better performance in real rooms. With a combined cone area equivalent to a single 375mm (15”) cone, they deliver staggering bass extension of exceptional purity. Incredibly lucid over an expansive sound stage, with no discernible distortion - whatever sounds you’re into,this is a supremely musical performer.
Model 205
In all the other Reference Series models, the wide dispersion UNI-Q/Hypertweeter pod is faired into the cabinet itself. For the smoothest possible response, much attention has been paid to evening out flux profiles. Both MF and HF coils in the UNI-Q array share a compound twin neodymium magnet assembly, and the two ultra-low distortion 200mm (8”) bass drivers have balanced Faraday loops above and below the coil to ensure perfect symmetry.
The listening experience is spine-tingling, off-axis as well as on. Wherever you sit in the room, there’s a near perfect illusion of presence - exactly what you want for auditorium quality home theatre or to recapture that elusive live concert ‘feel’.
Model 203
The 203 shares all this technical virtuosity, only on a slightly smaller scale. Computer matched high order four-way crossovers assure fluid transitions between the five drivers. The Hypertweeter and the new UNI-Q coincident source array together provide seamless mids and highs while the two165mm (61/2
”) LF drivers with KEF’s high-tech motor systems and stiff, lightweight reinforced diaphragms, deliver deliciously open bass with incredibly low distortion even at high volume. Stereo imaging is superb,the detailing immaculate and the response so fluid you could almost drink it.
Model 201
All the latest Reference Series technology packed into a neat bookshelf package. There’s certainly no compromise on build quality either. Graded and hand soldered OFC wiring. Audiophile crossovers with air-cored inductors and polypropylene capacitors. Gold plated terminals. Like all Reference Series models, the 201 can be tri-wired and comes with a boundary control device to fine tune response to the acoustics of the room. And with full magnetic shielding and the inherently wide dispersion characteristics of KEF UNI-Q, you can place them more or less wherever you like. Smooth. Sweet sounding. Startlingly clear. The 201 is big in everything but size.
Model 206DS
Designed to partner the new Reference Series,the Model 206DS is a dedicated dipole rear surround for no nonsense KEF Reference multi-channel systems. Incorporating two of the radical new UNI-Q point source arrays as used in the Reference Series,partnered with two 19mm (
3
/4
”) titanium
dome Hypertweeters and twin 165mm (6
1
/2
”) low distortion bass drivers, the Model 206DS is perfectly timbre matched to the other Reference Series speakers. The four-way Model 206DS contains the technologies developed for the Reference Series; a Boundary Compensation Device, Reference matched drive units. The technologies combine to produce an incredibly lucid sound reproduction,to ensure your enjoyment is complete.
Model 204c
With around two-thirds of the average movie soundtrack playing through the centre channel, KEF’s extended bandwidth technology has been applied with particular care to the new Reference series centre speakers. Adding the Hypertweeter to the new UNI-Q driver array provides the extra bandwidth required to reproduce all the audio inf ormation encoded in the latest digital formats. The array is completed by audiophile quality 165mm (61/2
”) bass drivers on either side, with ultra-low distortion motor systems and reinforced lightweight diaphragms to recreate the full weight of frontal effects without sacrificing subtlety at lower volumes.
Model 202c
The recommended centre speaker to partner models 203 and 201, the 202c delivers all the listening benefits of the latest Reference Series technology. With the same Hypertweeter and an identical UNI-Q array incorporating KEF’s latest elliptical dome titanium tweeter and seamless Uni-Form cone/surround, the all-important vocals are reproduced with the same stunning realism. When flanked by a pair of KEF’s 165mm (61/2
”) ultra low distortion bass drivers, the combined effect is to immerse the viewer in a detailed soundscape that’s as lucid as it is involving.Irresistible.

The look of XQ - an evolution of the new Reference Series aesthetic - is about function,not fashion. From the chromed steel Hypertweeter
TM
pod to the curves of the cabinet, everything is calculated to produce a cleaner,purer sound. Admittedly, the finish is a bit of an extravagance. You can specify your XQ system in either a cool,Natural Maple veneer or one of four high gloss lacquer finishes: Silver and Graphite Metallic (to complement AV equipment),Pearlescent White or Maranello Red.The aluminium front baffles are anodised in Silver.
But hey - when the technology inside creates such beautiful sound, they deserve to look special. With all models magnetically shielded and identically voiced, the XQ Series fills the room with the kind of breathtaking auditorium quality 3D soundscape you normally only find with the world’s most expensive speakers.
XQ five
Tall, slim and assertive, XQ five is a genuine four-way floorstander with two 165mm (6
1
/2
”) bass drivers in
addition to the 165mm (61/2

array and KEF’s new titanium dome Hypertweeter. What you experience is a big, all-enveloping sound image, perfectly controlled. Exquisite detail, wherever you sit. Exceptional lucidity, whatever the volume ­uncannily so,with the latest digital formats. If you want sound that takes you out of yourself, take five.
XQ three
All the sophistication of XQ five in a chic stand-mount format. The look may be disarmingly simple, but there’s no mistaking the richness and complexity of the sound image XQ three can create. When you hear what you’ve been missing,you suddenly understand what SACD and DVD Audio are all about. All you have to do is choose which of the sumptuous contemporary finishes best complements your room: Natural Maple veneer, Silver, Graphite Metallic, Pearlescent White or Maranello Red.
XQ one
Irresistible - the compact three-way stand mount speaker that’s packed with Reference Series technology. Don’t be fooled by the relatively small size. Power handling is exceptional, and UNI-Q’s inherent wide dispersion characteristics fill any normal room with an expansive soundscape. Magnetically shielded like the rest of the range, it’s equally at home shelf-mounted or on the available dedicated stand. If you’re after true audiophile quality wideband response without breaking the bank,this is the one.
XQ two c
Serious technology - and rightly so. Watching movies, nowhere is acoustic accuracy more important than in the centre channel. The overall effect is so real it’s unreal - all the more so with digital media. The rustle of a breeze. Fingertips on frets. Distant thunder. Shoes creaking. Cicadas in the grass. The flautist’s intake of breath. You’re there,simple as that. You don’t even need to look - you need two c.
