UNPACKING AND VISUAL CHECKS
To remove the speakers from the carton without damage, open the box in the upright position and fold back the four flaps.
Remove the top foam packaging and power cable then lift the unit out by gripping the cabinet, not the tweeter pod. Place the
speaker on a stable surface and inspect for signs of transit damage - please note that nothing on, or in, your speakers should
rattle. In the unlikely event of transit damage inform the carrier and supplier; keep all the damaged packaging, as this will show
evidence of any careless handling.

PRELIMINARY RECOMMENDATION
A word of warning on high sound levels - these speakers are capable of generating high output levels over sustained periods
of time and such levels, over 95dBspl for 8 hours per day, can eventually cause permanent hearing loss. Since Tannoy monitors
have a natural-sounding flat frequency response and low distortion, it's possible not to be aware just how high the sound level
is high while working with them.
For continuous exposure we recommend the occasional use of a sound level meter. This should be capable of integrating the
sound level over a period of exposure according to noise control standards and used just to check that noise levels are always
within safety limits. It is usually accepted that 80dBspl is a safe level for continuous exposure.
CABINET
Along with drive units, the enclosure design plays a major role in the acoustic performance of the monitoring system. A wide
variety of shapes, techniques, and materials were researched, to arrive at the elegant, functional and eye-catching elliptical
cabinet design. The form of the Tannoy Ellipse is significant. Conventional rectangular, sharp cornered boxes tend to suffer from
diffraction and reflection problems caused by the cabinet boundaries - the often overlooked cause of many irregularities heard,
and emitted sound field degradation measured, in the higher frequency areas.
With Ellipse however, these side diffraction anomalies have been minimised, and the SuperTweeter™ housing shape and position
facilitate consistent, wide dispersion and accurate time-alignment, both on and off axis. The overall cabinet design concept is
so effective at minimising diffraction effects because the distance from the centre of the driver to the smoothly rounded edge of
the cab is constantly changing, as is the angle of the diffracting edge, so these unwanted diffraction products are diffused in
both time and direction.
The laminated birch construction, with its massive MDF front and rear baffle panels, is inherently stiff. This results in an enclosure
that is non-resonant, both acoustically and mechanically, while providing the optimum volume for the Dual Concentric™ drive
unit for accurate low frequency reproduction.
AMPLIFIER MODULE
Given the increased accuracy and flexibility of active crossover and equalisation circuits, meaning that flatter frequency responses
and better phase alignments are possible, it's understandable the integrated active type of speaker system has become the
standard in near-field monitoring. This format is the basis of the Ellipse. ASP is employed to optimise frequency response and
phase / time alignment, and provide extensive user equalisation to compensate for a range of installations and applications.
Premium grade components lie at the heart of the amp module, with 350 discrete components and 28 integrated circuits mounted
on a compact surface mount technology PCB. The power amplifiers incorporated are compact, reliable and high quality, tailored
to their drive units, with high dynamic damping of diaphragm overshoot and ringing.
