KEF EG Ci50R Handbuch

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 downlighting. 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 your tastes

and décor. As visually discreet as a

speaker can possibly be, the Ci50R

delivers 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 unobtrusively as possible, and

with KEF's standard lighting style fitting,

you'll also find them amazingly easy and

rapid to install.

Loudspeaker installations don’t come

more discreet than the Ci50 Soundlight

System. A full bandwidth sound system

consisting of four satellite speakers and a

twin-ported subwoofer, the only visible

components are designed to be virtually

indistinguishable from a standard 50mm

low voltage light fitting once installed.

The subwoofer itself is hidden out of sight

in the ceiling void, 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

performs, though - by combining high

quality drivers with innovative KEF

engineering, response is fluid and accurate

across 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.

The quality of a speaker is no less

important just because it’s out of sight - in

fact, with ceiling-mounted units, it can be

more so. Designed to smoothly integrate

and architecturally match with existing

downlighting sharing the same size bezel,

KEF’s trademark Uni-Q®technology has a

decisive performance advantage in these

applications, because each point source

driver array evenly disperses the sound,

ensuring a smooth frequency response

over a large area to create a spacious

three-dimensional soundscape with

genuine texture and depth.

With a Uni-Q array of 80mm (3”), the

Ci80QR is as satisfyingly musical to hear

as it is neat in appearance.

Features and Benefits:

Purpose built for flush mounting into walls

and ceilings these are the latest addition to

the KEF Uni-Q Custom Installation series.

Providing a compact solution to the

problem of Hi-Fi quality sound from an

in-wall/ceiling speaker, the 80QR consists

of a polypropylene cone LF driver with the

HF unit mounted at the acoustic centre of

the LF unit.

The bezel and grill can be painted to match

the interior décor.

When partnering with others in the range

try the Ci130DS as the perfect companion

for creating a high performance built-in

home theatre.

A 2-way, 3 driver, flush-mount dipole

loudspeaker, it can be mounted in the walls

or ceiling allowing far greater flexibility in

positioning than any of the competition.

Housed in the enclosure to ensure

optimum 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 properties 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) formats.

The stainless steel bezel and grille can be

painted or covered by fabric to match the

interior décor.
