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 R90 in Piano Black Lacquer

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”
