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 abso- lutely flush appearance when it is properly installed.

Removal of Speaker and Grille

Removing The Speaker

If the grille is already installed, remove it by using a bent paper clip or the tip of a cork- screw and pulling it away from the frame.

Utilizing two small screwdrivers or two needle nose pliers, release the snaps that hold the speaker to the frame. Insert the screwdrivers into the holes in the snaps and exert force straight down (towards the woofer) until the snaps release. Once the snaps release, the speaker can be tilted away from the frame to be removed. Do not attempt to use the frame for leverage, as this may damage the surface of the frame (See Figure 21).

Operation

Listening at Higher Volumes

It requires more power to achieve a reason- able volume of sound in a large room than it does in a small room. It is possible (even

if you are not a teenager) to turn the volume so high that the amplifier runs out of power.

This creates “clipping” distortion.

Clipping distortion makes treble sound very harsh and unmusical. When you hear harsh sounding treble from any good speaker, turn the volume down immedi- ately! Those harsh sounds are masking some much more powerful ultra-high-fre- quency sound spikes which will quickly damage any fine loudspeaker. You are much less likely to damage a speaker with a large amplifier because it will be very loud indeed before it produces any clip- ping distortion.

Cleaning

You can clean the speaker with a damp- ened soft cloth or paper towel. If the speaker is mounted high up on a wall or ceiling, use a broom to gently brush it off.
