Company History
Since 1972, Monitor Audio’s near fanatical commitment to quality in every aspect of
loudspeaker design coupled with its willingness to innovate has inspired global recognition
and acclaim. Daring to challenge design orthodoxy has been its signature approach.
When Monitor Audio launched its R352MD loudspeaker – the rst model to incorporate
a metal dome tweeter - it caused quite a stir. Until that time, most metal domes were
single-metal types made from copper or titanium and virtually all sounded unconvincing.
The R352 used an aluminium-magnesium alloy dome and sounded signicantly better
and smoother than all of its single-metal rivals. It also incorporated ferro-uid damping/
cooling of the metal voice-coil former and a vented voice coil mechanism for better heat
dissipation. These radical design elements formed the basis for successive generations of
C-CAM® metal domes.
By consistently rening and applying the technology, Monitor Audio has become the
world’s foremost proponent of metal dome drivers. Monitor Audio designs and builds its
own cabinets and crossovers as well, so that it can optimise the incomparable blend of
virtues that makes Monitor Audio loudspeakers unique: clean, dynamic sound, superior
build quality and innovative design. And because they share a philosophy of excellence
and a consistency of quality and voicing, loudspeakers of different types: on-wall, in-wall,
oor and stand-mounting, may be used together to create the perfect blend of colour and
shape for any room.
In the strength and depth of Monitor Audio’s evolving product portfolio, the ideal of a
universal whole-house loudspeaker brand nds true expression. Decades of accumulated
expertise and knowledge have rened the rare mix of innovation, reliability and sheer
performance that has propelled the brand to global status and on which acionados of
music and movie sound have come to rely.

Platinum. The new Flagship of Monitor Audio
Platinum is Monitor Audio’s new agship range. It is the culmination of many years R&D
by the award winning design engineering team within Monitor Audio. The Platinum Series
is the result of ‘blue sky’ thinking in driver technology and cabinet construction, involving
radical new materials, processes and designs. Supremely esoteric in nature, the range sets
new standards of aesthetic quality and performance in its class.
Platinum’s innovatively shaped cabinets are nished in a rich piano black laquer,
exotic Santos Rosewood and Ebony natural wood veneers, which are hand selected and
veneered to the cabinet after construction to ensure a seamless nish. They are then
coated with eleven layers of clear gloss polyester lacquer. The front Bafes are hand
upholstered in Muirhead, Strathspey leather and tted with new custom developed drive
units including, in a departure from tradition, a C-CAM® ribbon high frequency transducer.

Muirhead History
The company’s history can be traced back to 1758. In the 18th century, John Muirhead was
exporting chamois and glove leather to America. After some years of economic depression,
John turned to making glue from the raw skins and this business prospered until about
1820. John’s son James took over the business in 1826 on his father’s death. James had
thirteen children, the youngest of which was Andrew.
Andrew had learnt much in his father’s skin and glue works and when the business was
transferred to him in 1840 he named it, “Andrew Muirhead & Co”. In 1870 the company
moved to its present site, Dalmarnock Works, formerly a ax and jute mill.
Since that time the company concentrated its production of upholstery leathers in
conjunction with case, bag and shoe leathers. Over time the company’s upholstery leather
achieved worldwide recognition and is presently exported to over 30 countries. Case, bag
and shoe leathers were phased out of production in the 1960’s to allow the company to
meet the demand for its high performance leathers.
Today the company is acknowledged as the largest supplier of quality upholstery
leathers to the airline industry, supplying over forty airline and aircraft manufacturers
globally. Upholstery leathers for quality contract and domestic seating and specialist
automotive application still remain the largest proportion of production with many
bespoke and specialist applications also being catered for.
Natural Leather Characteristics
Real leather is a natural product. It breathes, is warm and has individual characteristics,
which make each hide unique. Leather will always bear the marks of its natural origin
and these characteristics can show as healed scars, growth marks, areas of differing bre
density and hair pore structure. These hallmarks in no way detract from the wearing
qualities of the leather. They are signs discerning owners cherish when buying leather. With
the passing of time and use, it develops a patina which enhances its beauty.
Monitor Audio Ltd. therefore cannot guarantee that the leather on each speaker will be
identical in colour, texture or aging properties. We can only assure you that the very best
products have been selected and used.

Care and Maintenance of Cabinets and Leather
The high gloss nish of the cabinet can be maintained by regular dusting using a soft cloth
or micro bre cloth. Should you feel the need to use a polish we would recommend an
abrasive free polish such as a good quality furniture polish. Always apply the polish to
the cloth and use sparingly to avoid contaminating the leather or drive units. The drive
units should only be cleaned with a damp cloth if more than normal dusting is required.
Cleaning of leather is perhaps something that is given too much emphasis. Leather
furniture in a normal domestic environment should require little attention and any cleaning
should be done only when necessary. It is not essential to the life of leather that it should
be cleaned regularly, but at the same time an accumulation of dirt and grease over a long
period is undesirable and obviously, the longer it is left the more difcult it will be to
remove. Dirt is abrasive and over a period of time in extreme circumstances will cause the
removal of the protective coating. Cleaning as described below is advisable.
Cleaning of Finished Leather
Use a cloth soaked in a mild soap/water solution (not detergent) and wring it out until
damp. Apply the cloth to the surface of the leather in a light circular motion, turning the
cloth regularly. Avoid an aggressive rubbing action. Repeat with a damp cloth rinsed in
clean warm water. To improve the life of the leather, follow these few helpful hints.
• Allow to dry and then lightly polish using a clean, dry soft cloth.
• Don’t use cleaning uids and preparations.
• Don’t over clean - leather really doesn’t take much looking after.
• Don’t use wax/spray polishes - upholstery leather is not the same as shoe leather.
Wax polishes and furniture spray often contain silicone which will, in time,
produce an unpleasant sticky feel to the leather.
• Don’t feed - modern leathers do not require ‘feeding’. Despite this, there is much
encouragement to use so-called hide foods, care kits, saddle soaps and waxes
- avoid them all.

TECHNOLOGIES
Ceramic Coated Aluminium/Magnesium (C-CAM®)
All the radiating surfaces of the Platinum drivers are formed from C-CAM, a material
originally developed by the aerospace industry for engine components. Its properties
make it ideal for loudspeaker cones: extremely rigid, yet light enough to yield high overall
efciency. In manufacture, the aluminium/magnesium alloy undergoes stress-relieving
processes to remove surface deformation and molecular weakness. Once formed, the
alloy cone undergoes a high temperature anodic coating process, in which a layer of
pure ceramic (alumina) is deposited onto its surfaces to give a completely rigid exterior.
Conventional cone materials are liable to ex (break-up) in operation, producing a
signicant level of audible distortion. C-CAM cones have a much higher resistance to
bending stress and therefore exhibit much greater delity.

RDT® (Rigid Diaphragm Technology) Mid-range and Bass Drivers
The bass and mid-range driver cones use RDT, a unique technology developed specically
by Monitor Audio’s engineers for the Platinum series loudspeakers.
Designed to reduce mass and increase cone stiffness, RDT applies ultra-thin skins of C-CAM
to a core of honeycomb Nomex material, creating a structure which is extremely light but
more rigid than a steel plate. At only 40μm thick, the C-CAM skins are half the thickness of
a human hair, yet when bonded to the hexagonal honeycomb core they form an RDT cone,
which is 150 times more rigid than a single layer of 200μm C-CAM alloy, but with a fraction
of the overall mass. These properties allow the cone to operate as a lightening-fast piston
for a clearer more natural sound. The cone’s new concave geometry has been rened by
FEA engineering to provide a smooth frequency response and eradicate break-up.
To optimise the performance of the RDT cone, Monitor Audio has developed motor
systems in which a focused magnetic gap and copper eddy rings work together to
produce a higher level of linearity and lower distortion than was previously possible.
Magnet plates and poles are CNC machined to very precise standards in order to provide
ultimate consistency.
The Platinum mid-range driver utilises an ‘under hung’ voice coil design to further
optimise linearity and reduce distortion. High energy NeFeB rare earth magnets are used to
provide high efciency and a large 2” (50mm) voice coil is specied to handle high power
input and dynamic impulses. Its RDT cone is directly driven by the voice coil to provide a
seamless mid-range and a natural integration with the bass and high frequency drivers.
The Platinum bass drivers use long-throw voice coil windings to provide large excursions
at high power levels. The 8” (200mm) bass drivers employ dual spider arrangements to
provide stability at high excursions. Their direct-drive RDT cones have no dust cap or joints
to interfere with the driver response over the working band.

Platinum C-CAM® High Frequency Ribbon Transducer.
A pure ribbon tweeter is highly regarded in the world of high-end audio as being the best
way to reproduce ultra-high frequencies and provide the most life-like transient response.
While this belief is well supported by fundamental physics, one listen will tell you that this
driver is very special indeed.
Platinum’s ribbon tweeter design uses an ultra-thin sandwich of C-CAM alloy suspended
in a powerful transverse magnetic eld of high energy NeFeB rare earth magnets. The
ribbon serves as both voice coil and radiating diaphragm, with every part of the ribbon
driven directly and simultaneously without energy storage. Having a mass of just 18mg, its
diaphragm is able to start and stop in an instant, producing a transient response capable
of dening the leading edges and expressing the natural decay of complex musical sounds
and all their harmonics. Specied to reach ultra-high frequencies up to an elusive 100 kHz,
Platinum’s magical ribbon tweeter will reproduce with ease every last nuance and detail
from high resolution audio formats such as DVD-A and SACD, together with the wider band-
width of HD-DVD™* and Blu-Ray™**.

ARC® (Anti-Resonance Composite) Bafes, Plinths and Mid-Range Driver Housings
The front bafes, plinths and mid-range driver housings for the Platinum series
loudspeakers are cast from hi-tech ARC material, a thermo-set polymer loaded with
minerals to provide extremely inert, optimally-damped components. Rened for
Platinum by Monitor Audio’s engineers, this type of material is used in high-tech automotive
applications and is ideal for acoustic design, where a high degree of structural rigidity and
vibration damping is required. The ARC material is cast to form a Tapered Line Enclosure
(TLE) for Platinum’s mid-range drivers. The TLE is a tapered enclosure, designed to prevent
the propagation of standing waves and modal resonances.
HiVe® II High Velocity Reex Port
Platinum employs a new type of port technology, which uses a straight ried design to
accelerate air ow and reduce turbulence. HiVe II technology has the ability to move air
in and out of the cabinet more quickly than a conventional port, bringing powerful bass
coupled with a superior transient response.
11
Cabinet Construction
The cabinets are constructed using exquisite real wood veneers* applied to MDF-ply
laminates shaped to form a rigid one piece shell. Internally, the sides are non-regular,
preventing the formation of standing waves. Monitor Audio has developed a uniquely
engineered ‘pin-hole’ internal bracing structure for the Platinum series, positioned to
provide rigidity and integrity with minimum air movement resistance. Cabinet bracing is
further enhanced by high tensile steel bolts that tie front and back panels to the ‘pin-hole’
brace which are tightened to a specic torque in order to tune out un-desirable resonances.
Bitumastic damping material is applied to all internal cabinet walls to provide a further
level of resonance damping.
Every Last Detail
WBT Platinum Signature contact terminals are considered to be of the highest
quality available. Precision-machined and plated with pure platinum, they provide very low
contact resistance and the best possible reliability. They feature accurate ne-pitch
adjustment and are suitable for heavy duty cables with spade, 4mm plug or bare
wire connection.
To provide secure, yet minimal contact with the oor, adjustable spiked feet are used.
Machined to the nest tolerances from high-grade alloy and anodized to the most
exacting standards, the feet accept ‘bullet’ spikes of high tensile steel, chrome-plated to
a mirror nish. A non-slip rubber pad is integrated within the foot design, when sited on
hard or solid wood ooring.
*Except for the Piano Black Lacquer nish.

PL100
A compact two-way loudspeaker featuring one 6.5” (165mm) RDT bass-mid
driver and C-CAM ribbon transducer. The PL100 has the superior bass denition and
articulate mid-range of the most accurate studio monitors, and its ability to generate the
deepest bass frequencies will redene expectations of a small speaker. Tonally, the PL100 is
supremely accurate, communicating a lifelike neutrality across its astonishingly wide
frequency range. A rigid cabinet construction, coupled with proprietary bracing techniques
and damping technologies provide the optimum environment for its ultra-low distortion
drivers, providing a sound which is remarkably transparent and rich in natural
expression. The PL100’s C-CAM ribbon tweeter extends its response way beyond the
auditory threshold to capture the ultra-high harmonic frequencies that are part of the
natural spectrum of sounds, preserving the entire micro-dynamic character of every
performance. It’s lightening-fast RDT bass driver will reproduce the power and scale
of dramatic passages with a transient response to match the ribbon tweeter, ensuring
consistent phase and breathtaking delity throughout the frequency band. The PL100 is a
truly compact, wideband speaker capable of reproducing accurately the most demanding
of music and lm scores.
The PL100 comes with a pressed, open mesh grille. This is invisibly held in place by high
strength neo-dynium magnets embedded within the, ARC bafe to give a clean nish to
the front. The grille is generally self-aligning when placed on the bafe, however, some ne
adjustment may be required.
For speaker positioning and connection options, please refer to page 23 - 26
Using the PL100’s Without the Monitor Audio Stand
Within the packaging of the PL100 you will nd 8 self
adhesive rubber disks. These are designed to be used
when the PL100 is positioned either on a bookshelf or
a stand by an alternative manufacturer. They isolate the
speaker and help to prevent it from moving along the
surface due to the externally mounted inserts.
Place them around the insert as illustrated to the right >

PL300
Standing at nearly 1.2m tall, the PL300 is a
With grille in place
majestic three-way oor-standing loudspeaker
comprising of two 8” (200mm) RDT bass driv-
ers, one 4” (100mm) RDT mid-range driver and
a C-CAM high frequency ribbon transducer. It
possesses the ability to generate the power
and scale required to ll a larger room with
awe-inspiring sound. Jaw-dropping dynamics,
combined with class leading agility give the
PL300 the power to paint the widest and most
detailed of sonic pictures. Through the application of advanced technologies, sound
balance is neutral, lifelike and totally rened. The PL300 is a true wide-bandwidth
speaker system whose range from 28Hz-100KHz is unrivalled in its class. Between
550Hz and 4KHz, the PL300’s ultra-light and rigid RDT mid-range driver operates with
lightening-fast precision to provide a remarkable transient response, aided by its dedicated,
proprietary Tapered Line Enclosure (TLE). Precision cast from ARC material, the TLE provides
a very inert, well damped chamber, whose shape is designed to prevent the formation of
standing waves, which impair the operation of the driver. To further reduce colouration by
preventing the release of residual energy to the main cabinet, the TLE chamber is decoupled
from the main cabinet housing by rubber isolation materials. The twin RDT bass drivers are
engineered to produce high excursions with extremely low signal distortion. Even at high
power outputs the PL300 will remain composed and free from any sign of distortion or
fatigue.
Further evidence of Platinum’s no-compromise design philosophy is revealed by the
‘outboard’ location of the PL300’s crossover, which is mounted in the cast ARC plinth to
eliminate magnetic interference and provide acoustic de-coupling from the speaker itself.
The ARC plinth also houses the bi-wire WBT terminals and provides convenient oor level
access.
The PL300 comes with a pressed, open mesh grille. This is invisibly held in place by
high strength neo-dynium magnets embedded within the ARC bafe to give a clean
nish to the front. The grille is generally self aligning when placed on the bafe,
however, some ne adjustment may be required.

PLC350
PLC350 is a substantial three–way, four driver centre channel speaker with the same
driver complement as the PL300. Armed with drivers and Platinum series technologies
of such potency, the PLC350 is able to reproduce frequencies from 32Hz to 100 kHz -
arguably the widest bandwidth of any centre speaker available. The range virtues of an
utterly neutral tonal balance and low distortion and cabinet colouration make the
PLC350 perfect for reproducing crystal clear dialogue. Given that at least sixty per
cent of the information generated by a home theatre system is reproduced by the
centre-channel speaker, the value of having as accomplished a design as the PLC350
in the role cannot be overstated. For a seamless transition of audio within the front
soundstage of a Platinum home theatre system, the PLC350’s tonal character and
performance matches perfectly that of the PL300, to generate a truly immersive, dynamic
and enriching multi-channel experience.
The PLC350 comes with a pressed, open mesh grille. This is invisibly held in place by high
strength neo-dynium magnets embedded within the ARC bafe to give a clean
nish to the front. The grille is generally self aligning when placed on the bafe,
however, some ne adjustment may be required.

PLW-15
Underpinning the drama and scintillating musical vitality of a Platinum multichannel
speaker system is the PLW-15, a range-matching sub-bass engine endowed with all
the quality, virtuosity and excellence that denes the marque. Capable of releasing the
deepest frequencies recorded on disc, the PLW-15 will drive performances of music and
lm with an utterly breathtaking authority. Its 15” (381mm) long-throw C-CAM driver is
triple-suspended in a rigid die-cast alloy chassis. A massive double-stack magnet
motor system with a 4” (101.6mm) voice coil provides the ultimate linearity and
control required to reproduce the clean seismic 16Hz tones that you feel more than
you hear. Powered by the staggering continuous force from the onboard Class D
amplier, the driver has the speed and integrity to complement the performance of its range
counterparts, creating the foundation for a seamless wideband sound eld, rich in
natural dynamism, texture and tonality.
With the convenience of remote control, the PLW-15’s subterranean potency can be
ne-tuned to the loudspeaker system using sophisticated digital lters, and to room
acoustics with a range of advanced DSP adjustments, including a ten band parametric EQ
and no fewer than four preset EQ positions. Its response can be optimised to meet the
specic demands of music and lm sound through individual input settings.
The PLW-15’s talent for room-matching is also expressed by the lustre of its beautifully
compact and curvaceous cabinet, resplendent in a choice of Platinum veneers and radially
braced and damped to enhance structural integrity.
Blending power and nesse with superb aesthetics, the PLW-15 introduces a sensational
new dimension to the experience of sound in the home, which celebrates the raw energy
and compelling quality of genuinely deep bass.

Positioning
The positioning for the Platinum Loudspeakers will be different for every single application.
This is due to the individual room’s acoustic properties and personal preference; every
room is different. We can advise you on ideal positioning as best as we can drawn from
years of loudspeaker experience.
None of the Platinum Series speakers are shielded. This means that if positioned too close
to a CRT television screen, distortion can occur. When positioning them next to a CRT
television be sure to site them far enough away to avoid distortion to the screen.
PL100
When the PL100 is used with the Monitor Audio bespoke stands, the height of the
speakers should be so that the tweeter is approximately ear height. If this cannot be
achieved, the listening angle can be adjusted to re them direct at the listening position.
This is achieved by adjusting the feet on the front and back of the stands. The same
applies when not using our stands, however, adjustment is limited to that of the
particular stand used.
When used in 2 channel, they should be positioned approximately the same distance
apart as you sit from them, approximetely 20 -50 cm from the rear wall and a minimum
of 50cm from side walls.
If you must have your speakers further apart than the ideal, ‘toeing’ them in a bit more to
a centre point can help to create the optimum central sweet spot.
For further positioning suggestions please refer to the images on page 25
PL300
When used in 2 channel they should be positioned approximately the same distance apart
as you sit from them, approximetely 0.5 - 1.5m from the rear wall and a minimum of 1m
from side walls.
If you must have your speakers further apart than the ideal, ‘toeing’ them in a bit more can
help to create the optimum central ‘sweet spot’.
For further positioning suggestions please refer to the images on page 25
PLC350
For those with acoustically invisible screens, the centre channel should be placed
behind it (in the middle), again ideally with the tweeter at ear height or no
more than 5°. The Monitor Audio PLC350 stand can be modied to tilt the loud
speaker upwards. This is achieved by swapping the front and back speaker supports to
provide a steeper angle. To do this, please refer to the stand assembly instructions.
If you are using another type of display system, place the centre channel directly below
(again in the middle) of the screen. Once again, the listening angle can be adjusted
accordingly by following the assembly instructions with the stand.

Fine Tuning
Fine tuning of your Platinum loudspeakers can be achieved in a number of ways, depending
on personal taste. Moving the loudspeakers further from rear and side walls will reduce
the bass, but add depth. The opposite will happen if you move them closer to rear or side
walls.
The slightest change to the position of the speaker, whether it is by moving it closer to a
wall or by toeing it in or out slightly, can effect the sound reproduction.
Soft furnishings within a room can have an effect on sound reproduction. Increasing the
number of soft furnishings can temper any apparent harshness. Conversely, if sound
appears dull, reducing the quantity will improve the sound.
Running-In
As with all loudspeakers, the Platinum Series Loudspeakers require a certain amount of
running-in time before the very best and optimum performance is achieved. A running-in
period of approximately 100 hours should be adequate. A gradual improvement will be
noticed throughout this period. The time required will depend on the conditions in which
they were originally stored (cold or warm), and general household conditions (again, cold
or warm).
During the running in period play them at approximately half of your normal listening level
so that the drive units are not overstressed.
