User manual TANNOY ST-200

[. . . ] 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. [. . . ] 1 Initial Positioning With a Tannoy Dual Concentric loudspeaker system, the low and high frequency radiation is generated on the same axis. This is done by mounting the high frequency unit behind the low frequency one, and coupling it to the low frequency radiator via a carefully optimised waveguide through the centre of the drive unit. Low and high frequencies are thus fully integrated at source, to give the most accurate reproduction. The sound will therefore appear to emanate from a point source a little behind the front of the speaker cabinet. The SuperTweeter then needs to be positioned to coincide with this point for best results. For this reason, an alignment gauge, covering our current and past models is included. 2, position the felt mat centrally on the loudspeaker enclosure, then the alignment gauge such that it is flush with the front of the cabinet. Use of the felt mat is optional, but does aid performance by preventing unwanted reflections from the cabinet top. Next, using Table 1, place the Performance Platform in the correct position for your loudspeakers. The distance shown is from the front edge of the cabinet, and refers to the letter coded marking on the alignment gauge. Note that due to the large distance involved, the alignment gauge is unsuitable for the Autograph- please use a tape measure in this case. Finally, withdraw the alignment gauge from under the Performance Platform, ensuring it does not move. The SuperTweeter is then positioned on the Performance Platform, making sure the front two cones engage the two indents in the SuperTweeter housing.

If possible, adjust so that the SuperTweeter is pointing at ear height when seated. After double checking the wiring, you are now ready to switch your amplifier on. [. . . ] The walnut enclosure has been hand waxed before dispatch from our finishing workshop. To maintain the natural wood appearance, it is important that only a wax of similar formulation is used. A jar of specially formulated wax is available from your authorised Tannoy dealer. This should be applied carefully (to avoid brass adjustment panel and terminals) and sparingly, with a soft lint-free cloth, such as muslin. [. . . ]
