An innovative blend of beautiful styling
and groundbreaking technical
achievement – sound and science in
perfect harmony.
A DESIGN CLASSIC
Tremendous dynamic range, agile, accurate and punchy bass,
with remarkable extension, fluid, open midrange and spacious,
airy high frequency, all combine to produce a performance on
a grand scale.
The compact design of the TD8 belies the effortless
ease with which it produces an enormous performance.
At the heart of Dimension is the famous Tannoy Dual
Concentric™ drive unit.
Featuring a cone material manufactured from a
composite of several different fibres and twin roll
surround, the system delivers enhanced midrange
performance and tight, fast bass with tremendous low
frequency extension.
A SUPERB LISTENING EXPERIENCE
The mix of fibres within the driver cone has been carefully
chosen to obtain a light but very stiff structure providing
chosen to obtain a light but very stiff structure providing
exceptional grip and control of bass transients.
Centrally mounted behind the Tulip Waveguide™, the driver’s
high frequency unit combines transparent, fluid performance
with true point source symmetrical dispersion properties.
While less imposing in size, the TD10 offers

performance of immense scale.
With stunning dynamics and seductive musicality. In common
with all models in the range the sheer presence and sound
staging ability of this speaker is captivating; the ideal choice
for listening rooms of more modest proportions.

A Tannoy SuperTweeter is incorporated into
the design of all Dimension models, not only
to resolve fine detail of high frequency
information but also to effectively enhance
the listening experience even at lower
frequencies. Creating an increased immediacy,
airiness and impact, the SuperTweeter makes
music more natural and true to life.
The low diffraction rounded edge of the baffle
combined with acoustically inert material
SUPERTWEETER
surrounding the SuperTweeter ensures that
high frequency output is not re-radiated,
resulting in superior imaging.
A hugely powerful, stunningly natural,
centre channel speaker.
Precisely tonally balanced to the other models in the Dimension
range. Voicing characteristics matched with such precision are an
essential part of achieving a home theatre system capable of
exceptional multi-channel imaging.

This loudspeaker is the award winning
flagship model of the Dimension range.
“I was won over by this highly musical and articulate speaker,
which provides the kind of dynamics and expressive realism
associated with higher prices.”
“Involving, entertaining, revealing and generous in scale,
the Dimension 12 reproduces any kind of music with pace,
life and rhythm.”

BI-WIREABLE TERMINAL PANEL
An innovative bi-wireable terminal panel
has been designed to simplify the
connection of even the largest diameter
audiophile loudspeaker cables. In addition
to the high quality gold plated speaker
cable connections there is an 'earth' or
'ground' terminal that is connected to the
chassis of the drive units.
Within any loudspeaker system the voice
coil will pick up radio frequency
interference that contributes to noise and
distortion when fed back to the amplifier.
The Dimension system of driver chassis
earthing optimises the performance of the
amplifier by reducing these effects.
Technical brilliance -
perfect music reproduction.
The TD-SUB underpins a Dimension
home theatre system with truly remarkable
low frequency performance.
Massively constructed around a 15” (380mm) drive unit, this
subwoofer uses a sophisticated, flexible and extremely potent
8
amplifier design to ensure the integrity of the powerful, deep
and controlled bass.

DIMENSION RANGE
Electrical filtering via the crossover is kept to a minimum
because the drive unit performance has been optimised
to form a near-natural transition throughout the
frequency range. The design is precisely customised to
our own engineers’ special demands utilising premium
quality non-standard components. This total system
view of crossover design ensures a far more natural
presentation of music to the listener.
The multi-faceted trapezoidal design of the immensely
strong cabinet reduces internal standing waves, further
minimising colouration. The cabinet, which is constructed
using birch ply for the primary panel components,
is comprehensively internally braced to improve rigidity
and further reduce the amplitude of panel resonance.
Heavyweight solid aluminium cones and floor- coupling spikes
ensure any residual cabinet energy is efficiently dissipated.

WIDEBAND TECHNOLOGY
™
BREAKING SOUND BARRIERS.
Modern programme material and sources (e.g. SACD / DVDA) have driven the requirement for
loudspeakers with extended frequency bandwidth performance. Always at the forefront of audio
evolution, Tannoy has been developing just such wide bandwidth loudspeaker technology over
many years.
Music contains transient information and rich harmonics beyond the range of human hearing for
pure tones. Even bass notes have leading edge transients reaching 30kHz. Operating between the
roll-off point of the Dual Concentric™ high frequency unit and 54kHz, the Dimension SuperTweeter
will accurately reproduce the leading edge of individual notes allowing the listener to experience
the entire bandwidth information of instruments.
In addition, by extending the frequency response by two octaves corrects time and phase response
within the bandwidth of normal human hearing. Taking these acoustical phase anomalies beyond
the range of human hearing adds realism to the soundstage by improving imaging and placement
of instruments.
SCIENTIFIC RESEARCH.
Musical instruments have energy up to and beyond 100kHz, but can we perceive it?
Researchers monitoring brainwave activity on subjects exposed to wide bandwidth material to
60kHz have conducted controlled experiments. By careful monitoring and noting subjective scores
under blind conditions, it was discovered that the listeners were indeed responding to the ultrasonic
components in the music.
Further experiments have deduced that profoundly deaf subjects rely on ultrasonic detection in
their discrimination of speech and tones. These tests concluded the mechanism was through bone
conduction, probably to a small organ in the inner ear called the saccule, which is effectively wired
to the cochlea, the organ responsible for hearing as we know it.
HOW DOES IT SOUND?
The proof as always is in the listening; whatever the source - whether vinyl, compact disc or the
latest SACD / DVDA technology. All of the technical features and attention to detail combine in
the Dimension models to provide discerning audiophiles with incredible wide band detail for the
ultimate musical experience.
The addition of a SuperTweeter, time aligned to the acoustic centre of the Dual Concentric, reduces
the high frequency phase error by moving the low pass roll off point much higher, typically –6dB @
54kHz, –18dB @ 100kHz. Research continues into the actual mechanism of the perception of sound
above 20kHz, but it can be clearly shown that the addition of a SuperTweeter will better preserve the
harmonic relationship between instruments. To illustrate this the trace below shows the phase error at
20kHz and 54kHz roll off points. There is clearly less phase error - not just at high frequencies, but
also as low as 5kHz.
