PERFORMANCE, TECHNICAL EXCELLENCE, INNOVATION,
SUPERIOR AESTHETIC DESIGN

MAKING SPACE FOR MUSIC & MOVIES
THE RADIUS CONCEPT
Many style-orientated speaker systems adopt a “high-
tech” look with interesting shapes and plastic casings.
With the Radius range however, Monitor Audio has
aimed for altogether more exceptional results, both
visually and sonically.
In developing Radius, we’ve remained true to the
principles that make Monitor Audio speakers so
sought after across the globe. There are no gimmicks,
no shortcuts, no fads - just a commitment to quality in
all its respects.
Combining advanced driver technology from our
acclaimed reference models with superlative build
quality and finish, Radius elevates traditional sat/sub
performance to a level which will astound lovers of
music, movies and design in equal measure.

BESPOKE WALL BRACKETS
AND STANDS
Position Radius speakers anywhere using the
high quality metal wall bracket supplied with the
satellites. Alternatively, use the super-chic
optional floor-stands for Radius 45, 90 and 180, and
the optional desktop stand for the Radius
225 and 250.
WIDE CHOICE OF FINISHES
Luxurious white and piano black lacquer finishes
join video silver and a selection of real wood veneers
to make décor-matching easy. With each Radius
speaker, perforated metal grilles are supplied
in black and silver to fine-tune the décor match.
25MM GOLD C-CAM® TWEETERS
Ceramic coated aluminium/magnesium was
originally developed by the aerospace industry for
use as blades in jet engines. It exhibits ideal qualities
for use as a tweeter dome, avoiding the ‘break-up’ or
bending distortions produced by more conventional
materials.
MMP® MK 2 BASS-MID DRIVERS
Monitor Audio’s second generation metal matrix
polymer cone material now uses a high-pressure
injection moulding process to achieve
different thicknesses at desired points of the cone
geometry. Greater cone stiffness and consistency
provide improved bass and clearer midrange
frequencies.
PERFORMANCE & VERSATILITY
Radius R90 in Walnut Veneer

RADIUS 45
The smallest speaker Monitor Audio has ever made.
Inspired by decades of design excellence, the Radius 45
represents Monitor Audio innovation at its most
concentrated.
With the R45 you’re assured the quality and
craftsmanship of our reference loudspeakers with
the versatility that comes with the Radius range.
The diminutive Radius 45 is a speaker with a
size-defying performance. Its secret is a rear-
firing gold C-CAM® tweeter, which spreads and
magnifies the sound around the room to create an
impressive effect. Designed to dovetail with the
Radius 360 subwoofer and available in the Radius
range of real-wood veneer, lacquer and grille colour
options, the super-compact R45 will blend with your
décor in any room you choose. Installing the R45 is easy
with the pivoting die-cast metal wall bracket supplied or
via an elegant stand-mount option.
If you love big sound but cherish your living space,
use the Radius 45 in an ultra-discreet stereo or
multi-channel A/V system and be surrounded by sound
not speakers.

RADIUS 90
Radius 90 is a high-class mini monitor. In contrast to the
stark metal appearance of most A/V satellites, it has the
same sumptuous real wood veneer and lacquer finishes
that grace Monitor Audio’s reference speakers. It offers
the same engineering standards and attention to detail
as well, right down to the radius-edged corners of the
cabinet and high-quality, gold-plated cable terminals.
Unprecedented enclosure rigidity and leading edge drive
unit technology combine to produce clarity, dynamics
and imaging abilities that are unparalleled in a speaker
of this size.
Use the R90 as a stereo speaker or blend R90s with the
R180 or R225 in the centre channel position. Underpin
the system with the rich deep bass of the R360 or R720
for stunning stereo and surround sound.
“The obvious prowess of this tiny speaker was frankly
a surprise; the sound is extremely animated, enjoyable
and engaging, yet excellent in conventional hi-fi respects
too, such as tonality, high and low frequency extension
and imaging.”

RADIUS 180
The slightly larger Radius 180 adds more bass to the
R90’s irresistible blend of virtues. It can be installed
vertically as a main, side or rear speaker, or horizontally
as a centre channel speaker in a multi-channel music
or movie system.
Its enhanced bass performance makes it the
perfect choice as a standalone speaker where a
subwoofer isn’t required. When combined with a
Radius subwoofer however, the R180 forms part of a
formidably powerful stereo or multi-channel home
cinema system.
As with the R90, the R180 is supplied with a high
quality die-cast metal wall bracket and a choice of black
and silver grilles. The elegant and optional Radius floor-
stand provides further positional flexibility.
“You feel the impact of every crash and gunshot
without it making your ears bleed. The 180 is finely
matched, and the whole package produces a cohesive
portrayal of surround steering effects”

RADIUS 225
By virtue of its very shallow depth, the Radius
225 is ideal for use with slim video displays or
Plasma TVs, as a centre channel or main speaker. The
sheer quality of its design provides the wonderful
accuracy of Monitor Audio’s reference speakers,
but its impressive size-defying bass performance
can be further extended with the addition of a
Radius active subwoofer. Use the R225s with the
R360 or R720 to create a compact, perfectly matched
yet sonically exhilarating audio/video speaker system.
Supplied with full-length black or silver grilles, and in
the comprehensive Radius range of finishes, the Radius
225 can be customised to complement its environment
from wall-mounted positions, via the slim-profile bracket
supplied, or from the desktop using the optional stand.
“This is an extremely fast sounding system and every
transient is dealt with razor-sharp precision. These are
disappearing speakers, not just because of the narrow
profile. Instead, the speakers produce a sound that
makes them ‘disappear’.”

Radius R225 in Video Silver

RADIUS 250
The outstandingly elegant and slender Radius 250 has
been designed to be sited vertically or horizontally
with larger 42 or 50-inch plasma displays. Providing
bass right down to 50 Hz, it can be used as a centre,
main, side or rear speaker in a multi-channel music
or movie system. At just 95mm deep, its suitability
for plasma screen applications or where space is at a
premium is unequivocal.
The Radius 250 employs the R225’s driver
configuration in a larger cabinet. Its enhanced bass
performance makes it a desirable space-efficient
hi-fi satellite for any room. Add the R360 or R720
subwoofer for even deeper bass definition and
further R250s or R225s in surround sound positions to
capture all the dramatic impact of multi-channel
music and movie sound. Now you can enjoy the unity
of high definition picture and high definition sound
with a system that enhances the look of your room.

RADIUS 270
At just 12cm wide, the Radius 270 is a super-slim
floor-standing loudspeaker designed for genuine
full-range performance in a serious stereo or multi-
channel audio/video system. The R270 employs an
array of technical developments derived directly from
Monitor Audio’s award winning reference speaker
ranges. Excellent fidelity and an elegant profile
provide the opportunity to enjoy great sound and
discreet design all in one package. Real wood veneer
and lacquer finishes add a lustrous appeal, giving
the Radius 270 a tactile sense of quality that feels at
home anywhere.
Use the R270 as a stylish hi-fi speaker or with the R225
or R250 satellites and the R720 subwoofer as part of a
room-friendly, high performance multi-channel music
or A/V system.
Radius R270 in Piano Black Lacquer

RADIUS 360
By any standards, the Radius 360 is a remarkable
product. This super-compact subwoofer has the speed,
subtlety and pitch accuracy to enhance the highest
quality music reproduction. It can also deliver the power
and slam demanded by movie soundtracks by virtue of its
downward-firing 8-inch driver, controlled by a powerful
built-in 100 watt amplifier.
The Radius 360’s weight and solidity belie its svelte
dimensions, which are so vanishingly compact that the
R360 can remain unobtrusive wherever you place it.
“Pleasingly the Radius sub has the virtue of
responding well at average settings – the kind you might
begin with by default. When running properly, the bass is
well integrated, taut, tuneful with respectable
extension.”
Home Cinema Choice Magazine
Radius R360 in Video Silver

RADIUS 720
The Radius 720 subwoofer proves that diminutive
dimensions and dynamite performance are not mutually
exclusive.
An evolution of the super-compact R360
subwoofer, its twin downward-firing 8-inch drivers
and powerful 250 watt amplifier combine to underpin
music and movie sound with a deep bass presence
that adds definition and scale to every performance. It’s
agile enough to bring a sense of momentum to complex
fast moving bass lines, and ruggedly efficient in its
delivery of plummeting bass transients. Most
remarkable of all though is its ability to provide an
explosive bass charge with an ease and authority
unprecedented for its size.
Its versatile control settings, compact dimensions and a
choice of lacquer, video silver and wood veneer finishes
make it the perfect partner for all Radius loudspeakers.
In harmony with the Radius philosophy, its design will
blend beautifully with any environment.

RSW-12
The RSW-12 active subwoofer provides another
stunning dimension to the Radius sound. Its
12-inch (300mm) C-CAM® front-firing driver,
powered by a potent 500W (RMS) digital amplifier,
will extend the reach of all the Radius speakers
to add the deepest drama to movies and music.
The RSW-12’s lowest frequencies are controlled so
expertly that even subtle effects are better
defined, enhancing the Radius experience with
bass you can feel as well as hear.
