The more sophisticated that digital audio

formats become, the better your speakers

need to be. Which to choose, though?

Manufacturers come and go. Design trends

appear, then fade away. But with KEF,

you’re dealing with people who’ve been

consistently innovating since 1961.

The KEF Home Theatre (KHT) Series is a

good example. By bringing audiophile quality

sound to affordable home entertainment,

it’s been breaking new ground ever since it

was first introduced. As its many awards and

5-star ratings prove, the original outperformed

every conventional system in its class.

The latest KHT systems extend this

advantage even further,whatever your budget.

With the introduction of radically

innovative concepts like Acoustic Compliance

Enhancement (ACE), the latest refinements

of KEF’s trademark Uni-Q technology and

a new generation of powered subwoofers,

there’s a formidable line-up of options to

choose from.

KEF and the multi award-winning KHT story

They’re all designed to reproduce ever y last

detail encoded in the latest home

entertainment formats, and having identical

drivers for the satellite and centre speakers of

each system guarantees a perfect tonal match.

Naturally, they’re all magnetically shielded to

avoid interference with your other equipment.

Although each has its own distinctive look,

every system is engineered with acoustically

inert cast aluminium enclosures and

high-end components including metal dome

tweeters to create an accurate and

compellingly real 3D soundscape - and with

the ultra-wide dispersion characteristics of

KEF’s Uni-Q point source array, it’s enjoyed

with equal pleasure by everyone in the room.

Based on those developed for the legendary

Reference Series,the Uni-Q arrays in the KHT

range are the most sophisticated yet,

with metal dome HF drivers that reproduce

the human voice with breathtaking accuracy.

In purely practical terms, the larger sound

image gives you far greater flexibility in placing

your speakers where they look best.For home

theatre, it means that you experience even the

subtlest 3D soundtrack effects with the same

clarity and realism wherever you sit.

Uni-Q

Excellent dispersion characteristics common

with all Uni-Q based products showing wider

listening area.

Conventional loudspeaker dispersion showing

narrow ‘sweet spot’.

Technology

KEF’s patented Uni-Q driver configuration

disperses the sound image over a much larger

area than a conventional speaker, instead of

being restricted to a small ‘sweet spot’.

This outstanding off-axis response is made

possible by using aerospace materials to

engineer a high performance tweeter that’s

small enough to mount in the exact acoustic

centre of the bass/midrange cone so that both

act as a single point source - an ideal that,

so far,only KEF has achieved.

03

ACE

Effect of ACE on a 10 litre closed box loudspeaker

The holy grail of loudspeaker design has always

been to generate big bass from small boxes.

The trouble is, the laws of physics make this

almost impossible to achieve, as bass extension

relates directly to efficiency and cabinet size.

Continuing a 40-year tradition of genuine

design innovation, KEF engineers have now

developed a way of overcoming this apparently

insoluble limitation. It’s called Acoustic

Compliance Enhancement (ACE), and it works

like this. In conventional speakers, cone motion is

restricted by the acoustic pressure in the

enclosure as the air is alternately compressed

and expanded by the cone moving in and out.

The smaller the enclosure, the greater the

pressure that acts on the cone. By dramatically

reducing this pressure, ACE allows the cone to

move as freely as it would in a much larger

cabinet, generating bass extension out of all

proportion to its actual size.

This is achieved by introducing granules

of activated carbon into the enclosure

- a material containing millions of pores

ranging in size from visible fissures to

holes a few molecules across. One of its

characteristics is a capacity for physical

adsorption, the gravity-like molecular force in

which a substance (usually a gas) accumulates

in a thin film on the surface of a solid. In the

ACE loudspeaker when the cone moves

inwards the air pressure increases,

triggering adsorption of air molecules from

the free air into the carbon.This removal of air

molecules from the free air causes the internal

pressure to decrease.When the cone moves

outwards the opposite happens and the

carbon gives out air molecules. The ACE

material is constantly acting to reduce the

pressure variations in the enclosure in a

controlled and linear fashion.

It’s an innovation that makes an amazing

difference for the listener. By enhancing

compliance by anything from 150% to 300%,

ACE-enabled loudspeakers perform like units

up to three times their size. In trials of

identical Uni-Q arrays fitted to an ACE

enclosure 40% smaller than the test cabinet,

not only did the listeners agree that bass was

undiminished - they unanimously preferred

the bass attack of the ACE version. And that’s

the acid test of any radical breakthrough in

audio design: subjectively as well as objectively,

ACE enriches the listening experience.

They may look cute - but they sound

anything but. Experiencing a movie or favourite

album through KHT1005.2 is like seeing an old

friend after a makeover: fresh, involving,

more intense.The centre and satellite speakers

all have KEF’s stunning 75mm (3in.)

Uni-Q driver - the smallest ever made,

its 15mm (0.6in.) metal dome tweeter and

double neodymium magnets deliver the

extended bandwidth you normally get with

much larger units.

The curvy die-cast aluminium enclosures

eliminate the diffractions and internal resonances

that so often blur the output of conventional small

speakers, so the sound is cleaner and crisper.

The sound image is completed by the KUBE-1

subwoofer,its 150-Watt onboard power amp

driving a side-firing 200mm (8in.) long-throw

bass unit and 200mm (8in.) ABR.With output

fully adjustable for phase, frequency and level,

its attack is as forceful as it is accurate.

Whether you prefer shelf mounting,

wall brackets or optional floor stands with

internal cable management, the installation is

as discreet as can be - until you press ‘play’,

and the whole room fills with immaculate

three-dimensional sound. High gloss black and

matt silver finishes available.

Charismatic is the only word to describe it.

Like the multi-award-winning KHT2005

from which it evolved, the reflex-ported

KHT2005.3

* pushes the performance

envelope of midrange home theatre like no

other system.

The specification tells part of the story:

with parabolic enclosures computer optimised

to eliminate cabinet distortions, the full

range centre and satellites all feature KEF’s

100mm (4in.) Uni-Q array incorporating the

19mm (0.75in.) aluminium dome tweeter from

the acclaimed Q Series. Ferrofluid-cooled for

better power handling and driven by twin

neodymium magnets, HF reproduction is

startling - even whispered dialogue is pin-sharp.

But the real magic lies in the way all the system

components work together.

The tonal match is perfect, and transitions

are so smooth you simply can’t hear them.

Like all KHT Series subwoofers, the matching

new 200-Watt KUBE-2 has a selectable

‘Bass Boost’ switch for even more bass ‘slam’

with movie sound effects,and individual phase ,

frequency and level controls allow you

to fine tune the output to get the perfect

balance with the satellite speakers and

your room acoustics.

An ingenious multi-directional base makes it

easy to place each satellite wherever it suits

you:on a flat surface ,at an angle on walls, or on

the optional floor stands. It all adds up to

a chic, superbly engineered system that

delivers way beyond what you’d expect for the

price. Available in high gloss black or matt

silver finishes.
