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.

Operation

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.
