KEF C7 User Manual

C Series

An unrivalled pedigree

For decades audiophiles around the world have revered
KEF (Kent Engineering and Foundry) for its innovative,
high-performance loudspeakers. The company was
founded in 1961 by Raymond Cooke OBE (1925-1995),
a former BBC electrical engineer, widely acknowledged
in the audio industry as a leading authority in transducer
technology.

The pioneering inventiveness of KEF loudspeakers was
undeniable. During the 1960s and early 1970s, KEF’s
reputation was further enhanced by its outstanding
performance. From the mid 1960s, KEF collaborated
with the BBC in developing new materials for high-end
loudspeakers - the results being embodied in the classic
LS3/5a monitor which generated worldwide sales of
more than 100,000 systems.

KEF’s Uni-Q® technology was introduced in 1988 and
since then KEF has maintained its position at the
forefront of loudspeaker and home theatre systems.

The core values of KEF: innovation, quality and
performance have ensured that KEF has one of the
best international reputations for audio excellence.

Incredible performers – whatever your taste…

New C Series is the product of a multi award-winning heritage of daring design, brilliantly executed. The range is engineered
for a perfect tonal match between every model, so you can combine them however you please. 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 can be used with virtually any amplifier and whether used for music, movies or
games, the sheer quality of the sound they produce is equally captivating.

C Series technologies

Aluminium dome tweeter with ‘tangerine’ waveguide

The same 19mm (0.75in.) tweeter 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.

Ultra-rigid enclosures

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 front baffle system.

Gold-plated terminals

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.

Dual signal transmission

To optimize 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.

Forward-firing slot port

Bass response is enhanced by a frontal slot port carefully contoured to
minimise any unwanted turbulence that might otherwise colour the
well-defined output of the bass drivers.

Invisible keyhole wall mounting system

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.
