Adjusting the Tweeter, Installing the Grille

Installation of the Speaker and Grille in New or Existing Construction

Adjusting the Tweeter

The tweeter is housed in a precision adjust- ment mechanism which enables precise aiming of the directional high frequencies to provide optimum performance. To adjust the tweeter:

1.Carefully grasp the tweeter housing by placing your thumb and forefinger in the indentations provided.

2.Rotate the tweeter housing either clock- wise or counter clockwise as required. The mechanism is indexed at equal intervals so that both speakers in a pair can be adjusted equally. Simply count the number of “clicks” as the first tweet- er is adjusted. Repeat the process for the second speaker, rotating the tweeter the same number of “clicks” in the opposite direction (See Figure 19).

3.Pivot the tweeter on both speakers equally by depressing the housing at the arrows until the desired angle is achieved (See Figure 20).

Installing the Grille

Carefully fit the grille into its recess so that it is barely in place. Starting with one corner, go around the speaker, pushing the grille in a little bit each time. You should be gentle, the aluminum grille can be easily bent out of shape. The speaker will have an absolute- ly flush appearance when it is properly installed.
