SUPERTWEETER-GO/ST300MG-SI
Introduction
Congratulations on choosing this precision hand-crafted component, to complement your Tannoy Dual Concentric loudspeaker system.
Before removing from the packaging and installing, please take the time to read these instructions, in order to prevent possible damage.
The PRESTIGE GR and ST-300Mg SuperTweeters are designed to provide the extended high frequency response demanded by modern
programme material and sources. Musical information contains transient information, beyond the range of human hearing for pure
tones. For music to be accurately reproduced, we find it essential to accurately preserve this information.
Even with conventional CD sources, the addition of a SuperTweeter reduces phase error and improves transient performance significantly
below 20 kHz. This leads to increased tonal accuracy at all frequencies, as the harmonics of instruments are not distorted in time.
This benefits any high quality loudspeaker, but especially the Dual Concentric, with its superior time alignment in the first place.
It should be noted though, that even with the addition of a SuperTweeter, the Dual Concentric still acts effectively as a coincident point
source, as it is still responsible for generating the vast majority of musical information. Further clear benefits result from improved high
frequency dispersion.
Although initially conceived to complement our modern Dual Concentric loudspeakers, these SuperTweeters will equally find application
with any of our earlier classic designs, be they previous PRESTIGE models, HPD, Monitor Gold or Monitor Silver for example. Adjustments
are provided for crossover frequency and level to enable accurate matching.
Features
• • High stiffness magnesium alloy dome to minimise effects of dome break-up and extend frequency response.
• • Neodymium magnet system also extends frequency response by minimising eddy current losses in the voice coil.
• • Provision for driver magnet system earthing to avoid interference and information masking caused by radio interference.
• • Very high purity silver plated matched crystal OFC internal wiring, PTFE coated dielectric.
• • Plated terminals and adjustment screws for high signal transparency.
• • Air core inductors in crossover for good high frequency characteristics.
• • Non-inductive metal oxide film resistors on ceramic substrates, avoid losses associated with wirewound types.
• • High quality polypropylene film capacitors, selected for high frequency use.
Unpacking Instructions
Caution: The magnesium dome on this SuperTweeter is very delicate. Although protected by a metal guard, take care to avoid pressing
on this during unpacking and installation, in case damage results.
Always keep the packaging for future use.
Environmental Considerations
Do not install the SuperTweeter in the following conditions:
• • Very warm or humid areas (such as near swimming pools, kitchens or bathrooms).
• • Near to a fire or heating appliance.
• • In direct sunlight.
Wiring
The SuperTweeter should be connected across your main speakers, positive (red) to positive and negative (black) to negative. Ensure your
amplifier is switched off, and the volume control turned fully down before beginning.
Single wired installation: The SuperTweeter is simply connected across your speaker terminals. An optional earth cable can be taken back
to your amplifier chassis or ground. (See Fig 1)
Bi-wiring installation: The SuperTweeter is connected across the HF terminals on your loudspeaker. Again, an earth cable may be taken
back to your amplifier, or to the earth terminal on Tannoy loudspeakers that have this provision. (Shown in Fig 2)
For optimum performance, the central earth connection on the SuperTweeter should be taken back to the amplifier chassis
or ground point. This screening effect can give an improvement in detail and clarity, depending on the amplifier used, by reducing radio
frequency interference.
It is important to use a high quality cable between the SuperTweeter and the main loudspeakers. A thick and heavy cable is not needed
for good performance due to the small signal currents involved and could pull the SuperTweeter off your loudspeaker causing damage.
