Tannoy Dimension Brochure

BREAKING SOUND BARRIERS.
Modern programme material and sources (e.g. SACD / DVD A) 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 - 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 DIMENSION RANGE

TD12

TANNOY DIMENSION. SOUND SCIENCE

The new Tannoy Dimension range.
Loudspeakers with the natural ability to
generate the scale, the excitement and impact
of recordings and film sound tracks.

Two heavyweight solid aluminium cones and rear floor-coupling spikes
ensure any residual cabinet energy is efficiently dissipated. The acoustically
transparent grille guarantees that there is no musical blurring.

The Tannoy Dimension series incorporates the
very latest wide bandwidth technology in an
acoustically optimised cabinet. An innovative
blend of beautiful styling and ground-breaking
technical achievement - sound and science
in perfect harmony.

A design classic.

At the heart of the TD12 is a 12" Tannoy Dual Concentric™ drive unit featuring a new cone material and twin-roll surround
providing enhanced midrange performance and tight, fast bass with tremendous low frequency extension.
is manufactured from a composite of several different fibres. The mix of fibres has been carefully chosen to obtain a light
but very stiff structure providing exceptional grip and control of bass transients.

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. The SuperTweeter
creates an increased immediacy, airiness and impact making music sound more natural and true to life.

The low diffraction rounded edge of the baffle combined with acoustically inert material
surrounding the SuperTweeter ensures that high frequency output is not re-radiated, resulting
in superior imaging.

The cone material

An innovative new 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.

System improvements are apparent using conventional high quality
cable and a separate earth lead to the amplifier ground. Further
optimisation is possible with the use of a screened loudspeaker cable.

Technical brilliance - perfect music reproduction.

A superb

Electrical filtering via the system’s 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 crossover is then precisely customised
to our own engineers’ special demands utilising non-standard
component values specified to an accuracy of two decimal
places. This total system view of crossover design ensures
a far more natural presentation of music to the listener.

Cabinet material and construction is a vital ingredient of loudspeaker design. Solidity and
neutrality are the key elements sought by Tannoy's acoustic engineers when optimising
performance levels. The Dimension cabinet utilises birch ply for the primary panel components.
Due to the anisotropic nature of this laminated solid wood material, the effects of cabinet
colouration, which would otherwise impair musical accuracy, are greatly diminished.

The multi-faceted trapezoidal design of the cabinet reduces internal standing waves, further
minimising colouration. The cabinet is comprehensively internally braced to improve rigidity
and further reduce the amplitude of panel resonance.
