TANNOY WideBand
™
SuperTweeter
™
Continuing the frequency response to 50kHz, the pod-mounted SuperTweeter
™
uses a specially developed dome with a
rare earth magnet. The SuperTweeter is time-aligned to the Dual Concentric
™
, over a wide horizontal dispersion using
custom DSP generated filters. The crossover frequency is very high at 20kHz, well away from the mid frequency band where
sensitive stereo location information is concentrated. Listening at 1 metre on axis with the high frequency horn, the precise
point where the signals synchronize, the SuperTweeter
™
is undetectable as a separate source.
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 minimized, 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 minimizing diffraction effects because the distance from the centre of the driver to the smoothly
rounded edge of the cabinet 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.
High efficiency compact Switched Mode Power Supply (SMPS)
For saving on power consumption and to insure optimal performance, disregarding the quality of mains voltage, the unit
is equipped with a high efficiency compact Switched Mode Power Supply (SMPS). Using switched technology both in amplifiers
and power supply can reduce the heatsink size to about one third the size it would be with a regular power supply and
class AB amplifiers.
Unpacking & 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.
