Introduction; Driver Technology - Tannoy Revolution XT Owner's Manual

INTRODUCTION

Thank you for selecting Tannoy loudspeakers developed in the UK by our dedicated team of design engineers.
They are the choice of discriminating music lovers the world over. Musical excellence is designed into our
loudspeakers from the start. Careful selection of the very best components combined with strict quality control
procedures in the production process ensures this level of excellence is maintained.
To gain maximum performance from your loudspeakers, please take time to read this owner's manual in full before
installation. Once you have set up your new loudspeakers please register them on our website - this does not limit
your legal rights.
Loudspeakers are electromechanical devices that 'run-in' through use; performance will therefore improve
after an initial period of 24 hrs use. Once they have been further run-in over a longer period, there will be clear
enhancement of the stereo imaging, mid-band quality and bass performance characteristics.
We are confident that you will continue to enjoy your new Tannoy Revolution XT loudspeakers for many
years to come.

DRIVER TECHNOLOGY

The Tannoy Dual Concentric™
Tannoy Dual Concentric drivers have been incorporated into the Revolution XT loudspeakers. Intensive research
and development has produced an all-new version of this proven technology that builds upon the legendary
performance of this exclusive Tannoy driver design. This new driver, offers enhanced dispersion – creating an
even more uniform spread of sound around the listening environment. At the same time the introduction of the
Omnimagnet™ configuration allows the high frequency unit to be placed even closer to the acoustic centre of the
low frequency unit further improving time alignment between the two drive units.
The time coherent, point source and constant directivity nature of the dispersion characteristics inherent in the
Dual Concentric makes 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 for two
channel stereo or multi-channel home cinema, is strictly controlled to accurately reflect the sound engineer's
artistry. In nature all sounds emanate from a single point in space.
The high frequency unit of the Dual Concentric, centrally mounted in the throat of the main mid/bass driver, is so
positioned as to acoustically replicate this single point source; delivering an exceptionally natural sound with an
incredibly wide imaging ʻsweet-spotʼ which is further enhanced by the newly developed Torus Ogive Waveguide™,
creating an expansive soundstage with remarkably focused placement of images.
Wideband™ Technology
Tannoy has incorporated its own WideBand technology into the design of these drivers. Not only does this
exceptional in-house technology resolve fine detail of high frequency information but it also effectively enhances
the listening experience throughout the whole frequency range. The WideBand high frequency system creates an
increased immediacy, airiness and impact, making music and movie sound more natural and true to life.
Sounds contain transient information and rich harmonics beyond the range of human hearing for pure tones.
Even low frequencies have leading edge transients reaching 30 kHz. Tannoy WideBand high frequency units
will accurately reproduce the leading edge of individual sounds allowing the listener to experience the entire
bandwidth, by extending the frequency response well beyond that of conventional loudspeakers.
In addition, the extension of the frequency response, by fully two octaves, corrects time and phase response within
the bandwidth of normal human hearing. Taking these acoustical phase anomalies beyond the audible range adds
realism to the soundstage through improvements in imaging and the placement of sounds.
