4. There are four clamps “dogs” which

hold each speaker in place. Rotate all
the dogs inward.

5. Insert the loudspeaker into the cutout in

the ceiling.

6. The dogs are tightened via four

front-baffle screws. Tighten the dogs
by turning the screws clockwise,
while pressing the loudspeaker against
the ceiling. NOTE: DO NOT OVER
. Over-
tightening the screws may make the grille
difficult to install.

8. Install the grille into the speaker.
9. Repeat this procedure for the next


Removing the Grilles:
To remove the grille from the LSC-BG, obtain

a small paper clip (size #1, common) and

bend the last quarter inch of it into an “L”

shape. Holding the paper clip with a pair of

pliers, insert the end with the “L” into a hole

near the edge of the grille. Remove the grille

by pulling the paper clip towards you.
Painting the Speakers:
The speakers must be masked prior to

painting them. The inside circular portion

of the hole template can be used as a

paint mask. Remove the outside portion

of the template by gently pulling along the

perforation. Affix the mask to the front of the

speaker using a piece of tape. Fold the tape

onto itself to form a double-sided loop. Affix

the tape to the tweeter and place the mask

onto the speaker.
Painting the Grilles:
The LSC-BG grilles should be painted

before they are installed on the speakers.

The best results will be obtained by using a

spray gun or airless sprayer. Thin the paint,

and then apply several light coats. This

technique helps prevent clogging of grille

holes. Paint both sides of the grille to cover

all the white paint.

Listening at Higher Volumes
It requires more power to achieve a

reasonable volume of sound in a large

room than it does in a small room. It is

possible 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 immediately! You are

much less likely to damage a speaker with

a large amplifier because it will be more

difficult to produce clipping distortion.
