Tannoy Prestige SuperTweeter ST200 Manual - Initial Positioning

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. 

Firstly, with reference to Fig. 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.
