The sound & music are 50% of
the entertainment in a movie.

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 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.
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.
KEF's patented driver array, using aerospace materials to allow the tweeter to be mounted at
the acoustic centre of the midrange cone to create a single point source.This is what gives KEF
loudspeakers exceptionally wide dispersion characteristics, with everyone in the room
experiencing the same clear, accurate sound image.
A flat panel speaker configuration that reproduces sound with a wide directivity pattern
without restricting listeners to a particular 'sweet spot'.This diffuse radiation of sound waves
is ideal for reproducing ambient sound effects.
KEF's way of dramatically increasing the effective volume (and therefore output) of bass driver
enclosures by adding granules of activated carbon, whose adsorption characteristics reduce
resistance to each backward movement of the cone. ACE-enabled loudspeakers perform like
units up to three times their size, subjectively as well as objectively.
A patented KEF technology that effectively seals the gap between a moving mid-range cone
and tweeter, which has the effect of dramatically improving sound quality, particularly at
higher volumes.
Wireless transmission dispenses with running cables across the room to the rear speakers by
using radio waves from a discreet sender unit to transmit the audio signal to a receiver built in
to the speaker. KEF’s high performance wireless system ensures exceptional signal integrity
under even the most demanding conditions.
True to the ease of use that underpins the whole kit concept, Selecta-mount is KEF's ingenious
system of concealed brackets designed to simplify wall mounting.
Another KEF innovation, the Bass Extender is a hollow reflex-ported floor stand whose
additional volume helps to enhance bass extension.
Smart Bass allows optimum integration between subwoofer and satellite speakers in the
minimum time using a simple ‘plug & play’ architecture.

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
smallest Uni-Q delivering the extended
bandwidth you normally get with much
larger units.
The sound image is completed by the
KUBE-1 subwoofer. 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.
KHT1005.2
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.
With parabolic enclosures to eliminate
cabinet distortions, the full range centre and
satellites all feature KEF’s Uni-Q array for
better power handling and precise sound
quality - even whispered dialogue is pin-sharp.
Like all KHT Series subwoofers, the matching
new 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.
Available in high gloss black or matt
silver finishes.

Clearly an evolution of the award winning
3000 Series, the new KHT3005SE is the
latest version of the iconic‘egg’ home theatre
system, updated to provide an even stronger
audio performance with improved clarity
and detail yet maintaining the beauty and
style that helped make its predecessor a
reviewer’s favourite.
The revolutionary Uni-Q driver of the
satellite and centre speaker has been
enhanced by the addition of the ingenious
‘Tangerine’ waveguide, for improved
sensitivity and sound dispersion and have
been comprehensively engineered for an
even cleaner, smoother response.
The cast aluminium enclosures are shaped to
minimise internal resonance with KEF’s
Sealed Suspension Technology - SSTTM (patent
applied for) dramatically improves sound
quality and at higher volumes filling the room
with incredibly detailed 3D sound.
Carrying up to 60% of the sound, the centre
channel is vital in any home theatre system,
and the dedicated centre speaker is in a
class of its own providing an amazingly
clear dialogue in perfect timbre with the
satellite speakers.
Available in high gloss black and high gloss
silver finishes.
The cool minimalism of these slender cast
aluminium column speakers belies the
sophistication of the technology that makes
them sound so authoritative.
Flanked by a pair of long-throw bass drivers
with ultra-low distortion motor systems and
with KEF’s Uni-Q array the KHT5005.2
disperses a seamless sonic image evenly
throughout the listening area.
And what an image it is - richly textured and
spatially precise in every dimension.
Whether you’re watching a film or chilling
out to a few tracks, they sound as clean as
they look.
The sensational HTB2SE subwoofer pumps
out a genius distortion-free bass and with
the SmartBass TM ‘connect and go’ technology
compliments the perfect beat and
sophistication of the satellites.
The 5000 Series is also available with
Wireless technology for the two rear
satellites, providing freedom to locate almost
anywhere without the worry of hiding
lengthy speaker cables.
Available in high gloss black and matt
silver finishes.
