Tannoy SuperTweeter

The ST-200 Prestige SuperTweeter

Congratulations on choosing this precision hand-crafted component, to complement your Tannoy Dual Concentric loudspeaker system. Before removing from the flight case and installing, please take the time to read these instructions, in order to prevent possible damage.

The Prestige SuperTweeter is designed to provide the extended high frequency response demanded by modern programme material and sources. The Dual Concentric still provides the heart of the musical information as a coherent point source, but at extreme high frequencies is supplemented by the wideband SuperTweeter. Musical information contains transient information, beyond the range of human hearing for pure tones. For music to be accurately reproduced, we have found it essential to accurately preserve this information.

Although initially conceived to complement the Prestige HE range, from Stirling up to Westminster Royal, it 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 titanium dome to minimise effects of dome break-up and extend

frequency response.

• Copper clad aluminium voice coil on aluminium former for high power handling.

• Neodymium magnet system also extends frequency response by minimising eddy

current losses in voice coil.

• Provision for driver magnet system earthing (as in Prestige HE series), to avoid

interference and information masking caused by radio interference.

• High purity (99.999%) solid silver internal wiring, PTFE coated dielectric.

• Gold plated terminals, adjustment screws and circuit board for high signal

transparency.

• Radio Frequency quality inductors in crossover for good high frequency

characteristics.

• Non-Inductive Planar Thick Film resistors on ceramic substrates, avoid losses

associated with wirewound types.

• High quality polycarbonate film capacitors, selected for high frequency use.

• Unique Tannoy Performance Platform gives stable support and accurate variable

adjustment.

Unpacking Instructions

Caution:

The titanium dome on this SuperTweeter is very delicate. Although protected by a metal mesh, take care to avoid pressing on this during unpacking and installation, in case damage results.

Each flight case contains the following:

• SuperTweeter units x 2

• Performance Platform x 2

• Adapter plugs x 4

• Adjustment screws x 4

• Felt mat x 2

• Alignment gauge x 1

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. If appropriate, remove the two plastic blanking plugs in the terminals. Ensure your amplifier is switched off, and the volume control turned fully down before beginning. Typical wiring configurations are shown in Fig. 1:

A. Typical single-wired installation. The SuperTweeter is simply connected

B. Bi-wiring installation. The SuperTweeter is connected across the HF

C. Where appropriate, when using 4mm plugs for your connections, use the

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. For optimum results, our high purity silver SuperLinks are recommended, which are electrically screened and provide an integral earth wire.

across your speaker terminals. On optional earth cable can be taken back to your amplifier chassis or ground.

terminals on your loudspeaker. Again, an earth cable may be taken back to your amplifier, or to the earth terminal on Prestige HE models (shown).

supplied adapter plug as shown.

Two lengths are available from your authorised Tannoy Dealer:

STL-075 0.75m STL-175 1.75m

STL-075 is suitable for most models, while STL-175 is mainly for large horn loaded enclosures, such as Westminster, Westminster Royal, Autograph and GRF. Please check the length required for your speakers, should you require cable.
