Over four decades of
innovation and a passion for
engineering excellence has
established KEF as one of the
most respected names in
high-end audio.
The ideal that inspired KEF’s founder Raymond Cooke in 1961 was to reproduce recordings so accurately
that they sounded indistinguishable from live performance, which is why so many professionals (including
the BBC) adopted his groundbreaking designs. This spirit of continual innovation in pursuit of perfection
is what has driven KEF engineers ever since. KEF speakers are like no others, and few manufacturers
have pioneered as many breakthroughs in loudspeaker design - from radical new cabinet designs,
cone materials and driver configurations to the use of aerospace technologies and advanced sonic
modelling techniques.
So the new C Series is the product of a multi award-winning heritage of daring design, brilliantly executed.
Today, it finds expression in revolutionary concepts like the KEF Muon (www.kef.com/products/muon),
where ultra-sophisticated driver arrays are shrouded in giant Ross Lovegrove-designed towers of
superformed aluminium. The same talented engineers created the speakers you see in these pages,
with just as much attention to detail and engineering integrity.

The same
19mm (0.75in.) tweeter from
the latest Q Series reproduces vocals
with spellbinding realism – the unique
‘tangerine’ waveguide disperses its sweet
natural clarity evenly throughout the room
and provides excellent protection from
straying fingers.
UUllttrraa--rrii gg iidd eenn ccll ooss uu rr eess
The sound
you hear is untainted by any
internal resonance from the sturdily
constructed cabinet, thanks to careful
internal bracing and a dense dual-layered
baffle system.
MMaaggnneettiicc sshhii eellddiinngg
Freedom of
positioning is virtually unrestricted
because every C Series speaker is
fully magnetically shielded to eliminate
any risk of interference with other
electronic devices in the room.
GG oo lldd--pp llaatteedd tteerrmmiinnaallss
The exceptional acoustic definition
you experience depends on the
recorded signal being perfectly
transmitted, so the twinned binding
posts of the C Series are gold-plated.
DD uuaall ss iiggnn aall ttrr aann ssmmiiss ssii oo nn
To optimise acoustic resolution,
there are dual sets of binding posts
to accommodate bi-wiring, or, for the
cleanest possible response right across
the frequency range, bi-amplification.
FF oo rr wwaa rr dd-- ffiirrii nn gg ssll oo tt pp oo rr tt
Bass response is further extended
by a frontal slot port carefully
contoured to maximise low frequency
dispersion and minimise any unwanted
turbulence that might otherwise colour the
well-defined output of the bass drivers.

With no ugly brackets to
spoil the clean lines, it couldn’t be
easier to secure your C Series satellites
(upright or horizontally) to any suitable
vertical surface using the ingeniously neat
keyhole mounting point built into the back
of each cabinet.

Incredible performers –

The range is engineered for a perfect tonal match between every model, so you can combine them
however you please. Using the ingenious and highly flexible C6LCR (left/centre/right) for all five main
speakers, for example, gives you a home theatre system of truly epic capabilities. Not only does it deliver
precise and engaging vocals but it is also adept at producing a rich and extensive performance enviable
of any satellite speaker.
Ease of use and flexibility have been engineered into all C Series models from front firing ports for closer
positioning to walls, to the discreet wall mounting brackets fitted to each of the bookshelf speakers.
Even the floorstanders are supplied with dedicated plinths to provide greater stability.
Acoustically the C Series provides the sort of clarity, definition and spatial precision normally associated
with speakers of a much higher price. Power handling is uniformly excellent, so they’re easy to drive with
virtually any amplifier and whether used for music, movies or games, the sheer quality of the sound they
produce is equally captivating.
Choose between classic Black Ash or fine-grained European Walnut finishes - whatever your taste,
we’re confident that the C Series will hugely exceed your expectations of audio enjoyment.
The C1 pairs the superbly accurate
19mm (0.75in.) tweeter and ‘tangerine’
waveguide from the latest Q Series with
a slot-ported 100mm (4in.) midrange/bass
cone. Both sit on a dense two-layer front
baffle system to deliver a complex,
profoundly realistic and spatially accurate
soundscape. With excellent power
handling and a carefully tuned crossover,
the C1 delivers a generously full
performance that belies its discreet
appearance and modest size.

Clear, confident and natural sounding,
the C3 boasts KEF’s 130mm (5.25in.)
bass driver for impressively extended
low frequency response to complement
the seductive realism of the sophisticated
19mm (0.75in.) tweeter and ‘tangerine’
waveguide. The resulting soundscape
is warm, rich in detail and compellingly
three-dimensional, whether you’re
enjoying a favourite track or watching
a movie.

A competent and compact floorstander,
the C5 combines the latest 19mm

waveguide with two 130mm (5.25in.) bass
drivers in a slim, internally braced cabinet.
Meticulously tuned crossovers ensure
seamless transitions and dual binding
posts allow bi-wiring or bi-amplification.
Whatever the genre, whatever the
medium, the resulting sonic picture is
open, fluent and involving.

If you’re serious about sound, you’ll find
the C7 an endlessly gratifying companion.
With KEF’s phenomenal 19mm (0.75in.)
tweeter and ‘tangerine’ waveguide,
complemented by a pair of large 165mm
(6.5in.) bass drivers, an intricate and
disarmingly naturalistic three dimensional
sound image floods the room. As with all
of the new C Series models, the highly
rigid cabinet is vented by a carefully
contoured front port to provide a wide
and extended bass.

The vital centre channel is at the heart of
any 5.1 surround sound set-up - except
that the remarkable C6LCR can also be
used as front and rear satellites.
The latest 19mm (0.75in.) aluminium
tweeter with ‘tangerine’ waveguide is
flanked by two 130mm (5.25in.) LF
drivers to produce both a centre speaker
with precise and captivating vocals and a
powerful satellite adding depth and

Unobtrusively handsome, yet powerful,
the new C4 subwoofer provides an
incredible bass output with immaculate
control. With a 200W on-board amplifier
driving a 200mm (8in.) front-firing bass

distortion as meticulously as the rest of
the range and adds effortless depth and
weight to any performance.
