Tannoy Dimension Sales Brochure

In nature all sounds emanate from a single point in space. The high frequency unit of the Dual, centrally mounted in the throat of the main mid/bass driver, is so positioned as to acoustically replicate this single point source; delivering an involving and natural sound with an incredibly wide imaging 'sweet spot', which serves to create an expansive soundstage with remarkably focussed placement of vocals and instrumentation.

Tannoy's Dimension SuperTweeter™

25mm (1.00") 25 micron titanium dome, with neodymium magnet system.

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.

With The Beautiful TD-12 Loudspeaker Grills Fitted.

Tannoy Dimension Dual Concentric™

300mm (12.00") paper pulp cone with a twin roll impregnated fabric surround

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.

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.

Tannoy's Dimension Bi-Wireable Terminal Panel

At the heart of the TD12 is a 300mm (12.00") 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. The cone material 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.

The multi-faceted trapezoidal design of the cabinet, with it's sloping top and bottom panels, reduces internal standing waves to minimise colouration. The birch ply enclosure is comprehensively internally braced to improve rigidity and further reduce the amplitude of panel resonance.

The finish is a stunning combination of real cherry veneer and polished alloy trim. The matching SuperTweeter™, machined out of a solid block of alloy, sits on a cushion of black velvet so as not to re-radiate high frequency energy off the cabinet top panel. The acoustically inert velvet and the low diffraction rounded edge of the baffle ensure superior imaging. Two heavyweight solid aluminium cones and rear floor-coupling spikes ensure any residual cabinet energy is efficiently dissipated.
 

FEATURES:

The Tannoy Dual Concentric™ drive unit features a fibre composite cone material, carefully chosen to obtain a light but very stiff structure providing exceptional grip and control of bass transients, and twin-roll surround providing enhanced midrange performance and tight, fast bass with tremendous low frequency extension.

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 tremendous bandwidth of the Dimension models allows the listener to experience far wider bandwidth information of instruments than with conventional loudspeakers. This extended bandwidth benefit is not only restricted to SACD / DVDA technology however, these acoustic improvements are immediately apparent even when using a 'red book standard' CD player with a 20kHz upper frequency. The SuperTweeter™ provides an increased immediacy, airiness and impact making music sound more natural and true to life.

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 bi-wired, hard-wired passive, low loss, true 6th order Linkwitz Riley crossover is precisely customised to Tannoy's engineers' special demands, utilising non-standard component values specified to an accuracy of 2 decimal places. This total system view of crossover design ensures a far more natural presentation of music to the listener.

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 unit. 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.


The Dimension range is an innovative blend of beautiful styling and ground-breaking technical achievement - sound and science in perfect harmony.

 

DRIVE UNIT:

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. The mix of fibres within the driver cone has been carefully chosen to obtain a light but very stiff structure providing exceptional grip and control of bass transients.

In nature all sounds emanate from a single point in space. The high frequency unit of the Dual, centrally mounted in the throat of the main mid/bass driver, is so positioned as to acoustically replicate this single point source; delivering an involving and natural sound with an incredibly wide imaging 'sweet spot', which serves to create an expansive soundstage with remarkably focussed placement of vocals and instrumentation.

The time coherent, point source and constant directivity nature of the dispersion characteristics inherent in the Dual make it an accepted industry standard in studio monitoring. By exceeding the rigorous demands of the recording and mastering environment Tannoy can ensure that playback performance in the home, whether in two channel stereo or multi channel home cinema mode, is strictly controlled to accurately reflect the sound engineers artistry.

WIDEBAND:

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.

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.

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.
