KEF EG Ci50R, Ci50R Information Sheet

Imagine a speaker that’s no more
obtrusive than a standard 50mm (2”) low
voltage downlighter, yet powerful enough
to flood a sizeable space with high
definition sound and designed to smoothly
integrate and architecturally match with
existing do

wnlighting. Impressively vocal
and superbly balanced, the Ci50R is a
masterpiece of intelligent miniaturisation ­and thanks to the design and specification

of the drive unit, a deceptively
accomplished performer in real rooms.
It is available with White, Chrome, Brass
or Brushed Steel bezels to suit y

our tastes
and décor. As visually discreet as a
speaker can possibly be, the Ci50R
deliv

ers the listening pleasure to match its
outstanding value for all but the most
demanding installations.
Small is beautiful.

Features and Benefits:

Purpose-built for flush mounting into walls
and ceilings, the Ci50R delivers KEF audio
quality as unobtrusiv

ely as possible, and
with KEF's standard lighting style fitting,
you'll also find them amazingly easy and
ra

pid to install.

Loudspeaker installations don’t come
more discreet than the Ci50 Soundlight
System. A full bandwidth sound system
consisting of f

our satellite speakers and a
twin-ported subwoofer, the only visible
components are designed to be virtually
indistinguishable fr

om a standard 50mm
low voltage light fitting once installed.
The subwoofer itself is hidden out of sight
in the ceiling v

oid, with a 100mm (4”) dual

coil bass driver pumping sound into the
room via two ingenious flexible ports.
There’s nothing discreet about the way it
perf

orms, though - by combining high
quality drivers with innovative KEF
engineering, response is fluid and accurate
acr

oss the frequency range and the sound
image has astonishing clarity and power
for the speaker size.

Features and Benefits:

The Ci50 Soundlight System combines
10-100W per channel power handling and
88dB sensitivity

, for a maximum in-room

SPL of 92dB.

The Ci50 Soundlight System
is purpose-built for flush mounting into
walls and ceilings.

The Ci50R speakers are

mounted with

KEF's standard lighting style

fitting

. It is

available in White, Chrome,
Brass or Brushed Steel bezels.
The Ci50SW subwoofer is ceiling mounted
by using the joist or suspended ceiling
brackets included.

When partnering with others in the range
try the Ci130DS as the perfect companion
for creating a high performance built-in
home theatr

e.
A 2-way, 3 driver, flush-mount dipole
loudspeaker, it can be mounted in the walls
or ceiling allo

wing far greater flexibility in
positioning than any of the competition.
Housed in the enclosure to ensure
optim

um performance regardless of the

volume of cavity placement, the pair of

mid/HF units are angled 80° apart - to
obtain a dipolar radiation pattern - with
the bass unit firing on-axis to the listening
position.

The driver configuration is set
into a moulded baffle with smooth
contours to improve dispersion. With its
unique pr

operties such as switchable
bipole/dipole radiation pattern the
Ci130DS makes a versatile partner with
others in the range such as the Ci200.2QT

.

Features and Benefits:

Ci130DS combines 60W power handling
and 88dB sensitivity for a maximum output
of 106dB.
The 3-driver configuration has a mounting
depth of just 88mm (31⁄2”).
Best suited to high quality Music
Surround and Home Theatre applications,
for all the usual surround sound (including
digital) f

ormats.
The stainless steel bezel and grille can be
painted or covered by fabric to match the
interior décor.
