Tannoy Prestige SuperTweeter ST200 Manual - Fine Tuning
Fine Tuning
Once the SuperTweeter is fully run in, you are in a position to fine tune the system.
The settings chosen for SENSITIVITY and CROSSOVER FREQUENCY are those
recommended by Tannoy as being optimum for your loudspeakers. However listening
room acoustics and personal taste may dictate some adjustment. Remember that like a
subwoofer, the SuperTweeter should not draw attention to itself, but should offer a
natural enhancement to the upper frequencies.
The effect of the SENSITIVITY adjustment screw is to increase or decrease the
output over the full frequency operating range of the SuperTweeter, in 1.5dB steps.
The CROSSOVER FREQUENCY control offers 3 positions for the SuperTweeter
energy to be rolled in (Fig. 4).
The position of the SuperTweeter has been determined in Table 1 to correspond to the
acoustic centre of your Tannoy Dual Concentric model. However the user is free to
experiment with the positioning. For example, in difficult listening room acoustics,
the SuperTweeter may be brought further forward.
The SuperTweeter has a protective mesh grille which can be removed for optimum
performance. It is simply held in place by the magnetic field from its own magnet.
Carefully remove by gently holding the mesh on the edges and pulling forward. Take
care not to touch the fragile dome.
