CERTIFIED SUBWOOFERS
Three KEF Architectural subwoofers models, when combined with the KASA500 Audio System Amplier,
deliver THX
®
cered bass performance. For THX
®
Cered Select (rooms up to 2000 cubic feet), one
KASA500 is used, whilst two KASA500 are needed for THX
®
Cered Ultra (rooms up to 3,000 cubic feet).
The diagrams below show the number of subwoofers required, as well as the wiring and KASA500 sengs.

UNI-Q BENEFITS
KEFs signature Uni-Q Driver Array is a point source that places the tweeter at the exact acousc centre of
the midrange driver. The unique benets of Uni-Q makes it the ideal soluon for custom installaon:
SIT ANYWHERE
Equal direcvity sound of up to 160° delivers pinpoint imaging and eortlessly natural performance across a
huge listening area, ensuring everybody shares the same experience.
IN-CEILING LCR
By installing a KEF ceiling speaker as close to the front wall as possible, all listeners will hear the sound as if
it is coming from the screen, rather than from above.
DOLBY ATMOS FOR ALL
The huge o-axis response ensures that everybody in the front row receives all the informaon from the
rear Atmos channels, and everybody in the back row experiences everything from the front Atmos channels.

RECOMMENDED HOME THEATRE
SPEAKER PLACEMENT
Due to the impressive o-axis response of Uni-Q, KEF recommends slightly dierent speaker placement for
home theatre, designed to cover the whole listening area rather than cater for one single posion (or provide
subpar sound for all posions).
Front speakers should be posioned as wide as the seang area (with clearance from the side walls). The rear,
as well as any Atmos channel speakers, should be posioned in line with the front speakers. Surround speakers
should be posioned in line with, or just behind the Main Listening Posion. Both Surround and Rear speakers
should be posioned above ear height to assist in diusing ambient sounds throughout the room.
For Dolby Atmos, it is important for the overhead speakers to be posioned correctly, so that they work with
the other speakers to faithfully deliver the sound eects. KEF recommends the following placement, measured
from the side prole of the Main Listening Posion, and sll in line with the Front speakers. Note the
conguraons for the number of overhead speakers being used. Measure directly overhead from the middle of
the listening area, front Atmos speakers from the front row, and rear Atmos speakers from the rear row.

SETUP AND WIRING EXAMPLES
The following examples show some of the ways that KEF Architectural products may be used in your
project. Included are wiring diagrams and the product sengs required for each example.
SUB/SAT AND SOUNDLIGHTS
These diagrams show examples of how KEF Architectural speakers may be ulised. Addional speaker pairs
may be added, as long as good pracces are observed in regards to nominal.
KASA500
KASA500 has DIP switches on the rear to adjust the line output (high pass lter) and the internal DSP (for
KEF Architectural subwoofers). Please contact KEF Technical Support, or consult the DIP switch chart for
advice on the best sengs for your parcular KEF speakers and subwoofers. Also note that KASA500 may
be used in place of any ‘generic’ stereo ampliers in these examples.
NOTE: When Ci200QSb-THX is used with KASA500, ensure the CROSSOVER mode is set to bypass. When powered by a standard amplier
that does not feature a crossover, set the CROSSOVER mode to ON.
PRODUCT SETTINGS
KASA500, as well as some Architectural subwoofers, have mode selecon switches. The modes required are
found with each example. For example, the following icon shows the switch when BYPASS is selected.

SINGLE SPEAKER SOLUTIONS
KEF has two ways of bringing phenomenal sound into situaons where space is at a premium and only a
single speaker will t.
DUAL STEREO
The Dual Stereo special applicaon loudspeakers feature two tweeters and a dual voice coil woofer. Stereo
soundstage is created by combining the dispersion eect of the Tangerine Waveguide with asymmetrical
tweeter placement, as illustrated below.
Stereo Power Amplifier
STEREO TO MONO TRANSFORMER (CiTR-SM)
The CiTR-SM converts a stereo amplier signal into mono, allowing any KEF Architectural loudspeaker to
deliver all the music from a single unit, with all the room lling benet of Uni-Q.

ACCESSORIES
Steel Rough-in Frames
(See table for product code)
Rough-in Frames (new
construcon brackets) are
used with in-wall and in-ceiling
speakers and are available
for most models. Installed
during the pre-wiring of a new
construcon installaon, they
allow the installer to reserve
the space in the wall or ceiling
and simplify cung the perfect
hole size.
Steel Rear Enclosures
(See table for product code)
Metal Rear Enclosures (back
boxes) are available for most
models of KEF architectural
speakers. Installed during
the pre-wiring of a new
construcon installaon they
provide a sealed enclosure for
the loudspeaker and reduce
sound transmission to the room
behind the speaker.
AMPLIFICATION
KASA500
KASA500 is a powerful 2x250W Class D stereo amplier. With powerful, bespoke DSP ulizing KEF’s
propriety iBX technology that extends the bass depth dynamically, KASA500 unlocks the full potenal
of the driver’s power at any listening level. Custom EQ sengs opmise the performance of KEF
subwoofers into any installaon, and limitless system conguraons are possible through the inclusion
of high-level speaker and line level inputs, plus signal pass-through with full range or adjustable high
pass operaon. Rackmount ears included.
AMPLIFIERS AND ACCESSORIES
CiTR-SM
Stereo to mono adaptor. Allows
any KEF Ci product to play two
channels (stereo) from a single
speaker. Can be mounted near
speaker or equipment.
UNI-Q
®
Uni-Q technology is the building block of KEF's signature
sound. Uni-Q technology places the tweeter precisely at
the acousc centre of the bass/midrange cone, so both act
together as a single point source to disperse sound evenly
throughout the room. The result is the eliminaon of the limited
‘sweet spot’, allowing everybody sing at dierent spots
in the room to experience and enjoy the same natural,
detailed sound.
CAVITY RADIATION CONTROL
(CRC)
Cavity Radiaon Control is a unique open-back midrange
with acouscally absorpve foam design that eliminates both
midrange dips and signicant levels of distoron that are
typically found in other coaxial three-way designs. CRC is
crical to delivering a full, detailed and engaging performance,
unprecedented in this format.
WEATHERPROOF
On the pao, by the pool, or on a yacht, the KEF Ventura
Series outdoor speakers let customers enjoy music without
compromise. Engineered to IP65 standards, these rugged,
hard-wearing speakers can withstand even the most extreme
weather condions. All KEF round and square architectural
models can also be used outside when installed under
protected areas of the home, thanks to their IP64 cercaon
and UV treated plascs.
EXTREMELY LOW PROFILE
KEF’s incredible Ci-T Series is designed for delivering the
highest quality sound when mounng depth is at an absolute
premium. Even with a mounng depth of only 36mm, the Ci-T
Series speakers sll deliver exceponal KEF sound quality.
DUAL STEREO
For areas with space for only one speaker, KEF’s Ci Series Dual
Stereo model plays le and right channels from a single unit
containing twin tweeters and a dual voice coil woofer.
METAMATERIAL ABSORPTION
TECHNOLOGY (MAT™)
A truly revoluonary tool in the KEF acousc armoury, MAT™
is a highly complex maze-like structure that absorbs 99% of
unwanted sound from the rear of the tweeter, eliminang the
resulng distoron and providing purer, more natural sound.
THX
®
CERTIFIED
KEF Extreme Home Theatre products are cered to various
THX
®
levels - Select, Ultra and the awe-inspiring Dominus
designaons. Any system craed from these loudspeakers de-
livers KEF's own jaw-dropping acousc capabilies, with all the
drama and emoonal intensity of true theatre sound quality.
ULTRA-THIN BEZEL
Designed to sit ght to the wall or ceiling with no visible gap,
KEF architectural speakers disappear for an incredibly discreet
installaon. The ultra-thin visible rim around the speaker casts
virtually no shadow, while the bayonet style construcon
ensures a ght t and seal, even when installed on an
uneven surface.
FLUSH MOUNT
KEF’s Flush Mount range blends premium sound with premium
aesthecs. Sing completely level with the wall or ceiling with
no bezel makes these loudspeakers both easy to install and
sasfyingly frameless when in place. In fact, the only hint that a
KEF speaker is present is the natural, room-lling sound.
SOUNDLIGHT
As discreet as LED downlights, KEF’s ny Soundlight gives you
big speaker performance with outstanding sound coverage,
thanks to Uni-Q’s exceponally wide dispersion.
