Mezzo – An object lesson
in acoustic science
Mezzo is an entirely new family of loudspeakers which
offer staggering performance and earth-shattering
design techniques at incredible price points.
40 years of Mordaunt-Short
2007 sees the 40th anniversary of
Mordaunt-Short. orman Mordaunt and
Rodney Short went into partnership in
1967 to produce the world’s first
loudspeaker range. Models such as the
Festival, Pageant and Carnival were
received to rave reviews, something that
has continued with all the company’s
current ranges including Mezzo.
Mordaunt-Short has been responsible for
developing truly innovative and
legendary technologies such as
Continuous Profile Cone (CPC), V-Form
and Aspirated Tweeter Technology (ATT).
Throughout this period, the company
has built up the reputation as one of the
world’s most respected loudspeaker
manufacturers and one thing has been
a constant over the last four decades –
Mordaunt-Short’s absolute dedication
to producing affordable high quality
hi-fi for all.
In 2004, something of a evolution
took place at Mo daunt-Sho t. The
legenda y loudspeake manufactu e
p oduced the flagship Pe fo mance
model which e-w ote the ule book
and used some t uly g oundb eaking
technologies neve befo e seen in the
hi-fi wo ld. Pe fo mance has since
won countless awa ds a ound the
globe and is conside ed to be a
mode n classic.
Many of Pe fo mance’s most
significant featu es have now t ickled
down to the company’s new ange –
Mezzo. All this means that t ue hi-fi
bliss is available to a wide audience.
Consisting of a full loudspeake
se ies and a blend of scintillating
sound and t uly g aceful aesthetics,
Mezzo affo ds you the oppo tunity to
expe ience music and movies t uly as
those involved intended, and what can
be bette than that?
Mezzo

Technology
Core technology Mordaunt-Short’s flagship Performance challenged the
status quo when it was launched and embraced some
truly remarkable design innovations, many of which have
disseminated down into Mezzo.
Un que Br t sh des gn
All key technologies are designed at
Mordaunt-Short’s research and
development headquarters in London,
England. This means that each tweeter,
drive unit and cabinet is created for a
specific purpose – to integrate
seamlessly to produce an astonishing
sound for your music and video
collection. Mordaunt-Short is proud of
its attention to detail and desire to use
the very best material throughout its
ranges while delivering value for money.
To this end, the finish on each cabinet is
selected to mirror the designs of the
finest contemporary furniture.

ATT Aspirated Tweeter
CPC alum n um cone technology
Continuous Profile Cone (CPC)
technology produces predictable driver
performance by ensuring controlled
piston-like movement at low
frequencies and minimal break up at
higher frequencies. Lightweight yet
rigid anodised aluminium cones are
used for faithful dynamics. This
advanced technology ensures
stunningly realistic sound.
D g tal Sound Process ng (DSP)
The Mezzo 9 subwoofer features a
powerful DSP engine which can be
tailored to your exact set-up and room
acoustics.
otch filters allow response
anomalies (room modes) to be equalised
out and a Phase Compensation Filter
(PCF) enables accurate step-by-step
phase adjustment at the crossover point
rather than the usual basic phase
inversion switch on lesser products. The
crossover point is fully adjustable and
the roll-off rate selectable. A special test
CD and combined Sound Pressure Level
(SPL) meter/remote control are supplied
making set-up surprisingly simple.
In use the DSP’s engine is able to
implement ‘ ight’ modes and other
dynamic processing so that for instance
low level sounds are made louder whilst
at the same time explosions appear
quieter, ideal for late-night listening. All
these features can be easily controlled
from the intuitive display panel and this
kind of technology once again puts
Mordaunt-Short at the forefront of home
cinema entertainment.
Asp rated Tweeter Technology (ATT)
Mezzo uses patent pending proprietary
Aspirated Tweeter Technology (ATT) – a
truly groundbreaking design that was first
seen in the now legendary Performance
series. Using state-of-the-art injection
moulding, the elongated unit whose form
is defined by complex acoustic
principles – floats freely in a discrete
enclosure. Along its length are
strategically positioned vents eliminating
the colouration which plagues traditional
closed-back designs. This unusual
venting system means Mezzo’s high
frequency drivers literally ‘breathe’,
resulting in an open yet detailed sound.
Mordaunt-Short uses an advanced
aluminium dome tweeter which the
company has been perfecting for over 20
years. The ultra thin diaphragm and
compression moulded surround is
mounted on a low resonance chassis.
The tweeter utilises a high temperature
voice coil with liquid cooling and damping
to ensure controlled high frequency
performance with excellent detail.
Crossover
The components used in the crossover
were critically selected for their signal
path integrity including high quality
polypropylene capacitors in Dual Value
Parallel (DVP) configuration which
produce outstanding treble. Coiled
inductors with low current saturation
characteristics greatly reduce non-
linear distortion artefacts for an
extremely clean and detailed sound.
The crossover itself is isolate mounted
further reducing vibration and
unwanted resonance.
V-Form technology
An innovative driver cone connection
that creates a bigger, purer soundstage
and helps maintain assembly rigidity.
The surround thickness varies, aiding
accurate pistonic operation and
allowing the dish to operate freely,
delivering benefits in timing
performance.
Sound deadened dr ver baskets and
curved cab net des gn
The drive units are mounted on a
unique, critically profiled sound
deadened driver basket chassis with
elastomer damping which completely
eliminates unwanted resonance effects.
Most loudspeaker cabinets are
cuboid which generate standing waves
that affect performance. Mezzo
speakers employ a curved cabinet
design which minimises unwanted
internal reflections produced by parallel
planes. The cabinets themselves are
carefully folded and pressed to form an
extremely dense environment in which
to house the drive units which again
reduces distortion and resonance. Each
panel is made up of differing thickness
to aid dispersion and reflection of
standing waves. The curves also offer
an aesthetic boon as they give the
appearance of a far smaller cabinet but
in actual fact provide a bigger
enclosure for a more commanding
sound. Critical bracing is then used to
strengthen key areas of the cabinet to
ensure a superb sound.

Two-channel Enjoy two-channel stereo bliss with the Mezzo 2 stand
mount and Mezzo 6 floorstander.
Mezzo 2 standmount speaker
Belying its compact size, Mezzo 2
embraces ATT to produce a remarkably
expansive sound and stereo image and
is the ideal two-channel stereo speaker.
After a lengthy research process,
Mordaunt-Short has rewritten the rule
book and taken its legendary CPC™
(Continuous Profile Cone) bass drivers
to the next level. These combine with a
sound deadened driver basket for a
superb all round listening experience.
The cabinet’s curved shape
discourages the build up of standing
waves for a cleaner and more realistic
sound. Indeed it is unusual to get this
level of performance from such a small
speaker. Relax, sit back, close your
eyes and you’ll think you’re sitting before
your favourite orchestra or rock group.
Mezzo 6 floorstander
For the richest, most dramatic
soundstage, the Mezzo 6 floorstander is
unbeatable. Using twin 6½” CPC
mid/bass drivers but with the added
bass extension that only an elongated
cabinet can produce, this 2½ way
speaker produces a commanding
performance. A hand-picked wood
composite is laminated and pressed for
consistent reproduction of every
frequency. Once again, the incredible
ATT tweeter takes care of the high notes
delivering highly detailed yet controlled
treble to your ears. Let Mezzo 6 release
your music collection..

Mezzo 5 centre
The Mezzo 5 is a dedicated centre in
woofer-tweeter-woofer configuration
designed to deal with the demands of
dialogue in movies. Its ATT tweeter
integrates fantastically with the rest of
the range to produce awesome vocals.
The cabinet is a closed box design
while the infinite front baffle guarantees
consistent dispersion characteristics
and performance. In short, your movie
collection will burst into your living room!
Mezzo 1 rear effects/bookshelf
The Mezzo 1 proves that Mordaunt-
Short’s trademark sound can be
delivered from the smallest of cabinets
and offers a taste of genuine high-end
hi-fi at a more than attainable price. The
ATT tweeter is featured in its most
compact cabinet to date and coupled
with a 5¼" driver, this petite bookshelf
speaker offers a deep and rich
performance as well as an impressively
large sound stage. Mezzo 1 was
designed with two specific purposes in
mind; to act as a satellite or rear effect
speaker in a home theatre system or
as a sublime stereo bookshelf speaker
for smaller environments with
audiophile reproduction requirements.
Either way, these beautiful speakers fit
perfectly anywhere.
Mezzo 9 subwoofer
The Mezzo 9 is the result of an
exhaustive research and development
process with one aim – to produce the
ultimate sub at an affordable price. The
results are truly mind-blowing. Using dual
opposed 8" CPC ultra long throw woofers
in a force cancelling configuration for
ultra stability and minimal vibration, the
sub metes out a thumping 375 Watts of
power. All this comes from an incredibly
compact cabinet which integrates
perfectly into any listening environment.
The Mezzo 9 is designed to be used
in any combination from 2.1 right through
to 7.2 set-ups and uses a Class D digital
amplifier for efficient cool running.
It is also extremely user friendly and
lets you take control via an ergonomic
Sound Pressure Level (SPL) meter and
remote control in one handset.
Music/Movie/Game modes allow the sub
to be tailored for specific uses which can
be quickly switched between thanks to
presets.
Mezzo’s home cinema set-up will put you at the heart of
the action and let you experience every cinematic nuance.
The Mezzo1 and 5 produce a consistent and dynamic
sound stage while the Mezzo 9 subwoofer provides low-end
frequencies for maximum impact.
With Mordaunt-Short’s new Mezzo system you’ll be
selling popcorn at the front door as your friends flock to
enjoy your home cinema experience.
