High Performance Home Theatre Speakers and In-Wall Subwoofers
Extreme home theatre from KEF
With unique design innovations such as our Soundlight and Motorised ceiling
speakers along with cosmetic advances like our ultra-thin bezel (UTB), KEF has
led the way for custom installed music solutions. Like other Ci Series models,
what all such innovations have in common is the use of advanced technology to
give best-in-class acoustic performance, appearance and ease of installation.
Combined with innovative engineering tailored to the practical requirements of
the installer, our latest suite of Q and R Series Ci home theatre speakers and
installed subwoofers sets yet another new benchmark: custom installed speaker
systems with the acoustic performance of audiophile quality freestanding hi-fi
speakers. Incorporating the latest KEF technology the new home theatre speaker
models utilise the innovative and multi-award winning Uni-Q driver array,
derived from KEF Blade. Situated in its own enclosure, optimised for the best
possible acoustic performance, the Uni-Q produces wide sound dispersion
characteristics, whilst delivering an exceptionally accurate, fast and clean
midrange response with excellent dynamics and power handling —perfect for
install applications where space is at a premium but performance is not.
In-Ceiling Home Theatre: Ci200RR-THX
Featuring a powerful ‘sit anywhere’ Uni-Q driver array from our floorstanding
speaker, together with a 38mm (I.5in) vented aluminium tweeter and ‘tangerine
waveguide’, in a 200mm (8in) aluminium bass/mid driver, the Ci200RR-THX
projects acoustically as if the sound originates from the screen. Performance
is to home theatre standards, and dispersion is so wide and even that everyone
in the room enjoys the same precisely defined sound imagery. Along with the
KEF’s unique Ultra-Thin Bezel (UTB) design offering the slimmest possible rim
around the speaker, Ci200RR-THX can be gracefully integrated into any setting
to achieve the minimum of visual intrusion on the interior space.
In-Wall Home Theatre: Ci4 1 00QL, Ci3 1 6ORL-THX, Ci5 1 6ORL-THX
The all new tall rectangular range is designed and specifically engineered for
serious music and home theatre system front left, centre, right and side
applications.The Ci4 I 00QL in-wall speaker boasts a 100mm (4in) Uni-Q array
with three MF drivers of the same size. For larger spaces, the R Series
Ci316ORL-THX is a high output music and home theatre speaker in which a 165mm
(6.5in) Uni-Q array is complemented by a pair of 165mm (6.5in) MF drivers. For
the ultimate in home theatre sound, the Ci516ORL-THX extreme output speaker is
built around the same sensational I 65mm (6.5in) Uni-Q flanked by no less than
four I 65mm (6.5in) MF drivers. Both Ci316ORL-THX and Ci516ORL-THX are housed
within a rigid aluminium front baffle (metal grille supplied — an optional
black or white cloth grille is also available) to offer exceptional music and
movie output.
In-Wall Subwoofers
As complete systems, the range includes two superlative in-wall subwoofers,
one with four compact 100mm (4in) extended response bass drivers (Ci4 I
00QLb), the other with three powerful aluminium I 65mm (6.5in) bass drivers
(Ci316ORLb-THX). Not only do these two subwoofers provide a perfect visual
match to our home theatre speakers, but they perfectly enhance the speakers’
sonic capabilities into a true high performance discreet theatre system.
Refined yet gutsy, up to two of these powerful subs can be driven by one of
KEF’s sophisticated 2 x 250WPC DSP controlled subwoofer amplifier, the
KASA500. With both speaker and line level inputs, as well as a pass through
that can be configured for full range or high pass output, this formidable
amplifier is specifically engineered for the purpose, with limitless
connection and integration flexibility. With these premium additions, KEF’s
pioneering Ci Series range now offers a high-end home theatre speaker system
for every application. All are timbre-matched for a perfectly consistent
sound, so whatever combination is specified, you enjoy accurate, spacious and
richly detailed 3D sound throughout the listening area. Fast, easy
installation has always been a strength of the Ci Series. KEF’s ingenious
design features allow Ci speakers to be fitted quickly in a few simple steps.
Second to none in custom installation
Of all British loudspeaker brands, only KEF has a 50-year record of
innovation, pioneering the use of advanced materials and techniques like
finite element analysis to redefine the state of the art. This technology
leadership has always been what sets KEF’s custom installed systems apart.
Discreet in appearance, simple to install and engineered to last, these
systems allow everyone in the room to enjoy the same flawlessly natural,
totally involving sound as an audiophile quality hi-fi system.
