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

g

ood example

.

By bringing audiophile quality

sound to affordable home entertainment,

it’

s been breaking ne

w 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.

But the latest KHT systems extend this

advantage even further,whatever your budget.

With the intr

oduction 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 KHT story

They’re all designed to reproduce every 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.

And although each has its own distinctive look,

e

v

er

y system is engineer

ed with acoustically

inert cast aluminium enclosures and high

end components including ne

w metal dome

tw

eeters 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 new

KHT range are the most sophisticated yet,

with new 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

r

elates directly to efficiency and cabinet size.

Contin

uing a 40-y

ear tradition of genuine

design innovation, KEF engineers have now

developed a way of overcoming this apparently

insoluble limitation. It’s called Acoustic

Compliance Enhancement (A

CE), and it works

like t his. In conventional speakers,cone motion is

restricted by the acoustic pressure in the

enclosure as the

air is alternately compr

essed

and expanded by the cone moving in and out.

The smaller the

enclosur

e

,

the greater the

pr

essur

e that acts on the cone. By dramatically

r

educing 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 achie

v

ed b

y intr

oducing 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 r

emoval of air

molecules from the free air causes the internal

pressure to decrease.When the cone moves

outwar

ds 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 inno

vation that mak

es an amazing

diff

er

ence for the listener. By enhancing

compliance b

y 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 agr

ee that bass was

undiminished - they unanimously preferred

the bass attack of the A

CE version.And that’s

the acid test of an

y 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 is like seeing an old

friend after a mak

eover: fresh, involving,

more intense.The centre and satellite speakers

all have KEF’s stunning new 75mm (3in.)

Uni-Q driver - the smallest ever made, its 15mm

(0.6in.) metal dome tweeter and double

neodymium magnets delivering the extended

bandwidth you normally get with much larger

units.

The curvy die-cast aluminium enclosures

eliminate the diffractions and internal r

esonances

that so often blur the output of conventional small

speakers, so the sound is cleaner and crisper.

The sound image is completed by

the slot-ported PSW1000.2 subwoofer

*, its

100-Watt onboard power amp driving

a 200mm (8in.) long-thro

w down-firing bass

unit. With output fully adjustable for phase,

frequency and level, a ground lift to prevent

hum and a cinema setting for even weightier

bass punch, its attack is as forceful as it

is accurate.

Whether you prefer shelf mounting,

optional wall brack

ets or floor stands with

internal cable management, the installation is

as discr

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

and the whole room fills with immaculate

three-dimensional sound. Matt silver finish.

Charismatic is the only word to describe it.

Like the multi-award-winning KHT2005 from

which it evolved, the reflex-ported

KHT2005.2 pushes the performance envelope

of midrange home theatre like no

other system.

The spec tells part of the stor

y:

tions, the full range centre and

eature KEF’s new 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

whisper

ed

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

250-Watt PSW2010 has a cinema setting for

even more bass ‘slam’ with movie sound

eff

ects, and individual phase, frequency and

level controls allow you to fine tune the

output to get the perf

ect balance with the

satellite speakers and your room acoustics.

An ingenious m

ulti-directional base makes it

easy to place each satellite wher

ever 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.
