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
TIGHTEN THESE SCREWS. 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
speaker.
Directing the Tweeter:
The tweeter is directed by gently pushing
on the outside edge of the tweeter grille. It
will move 20° in any direction. For critical
listening, point the tweeter to the user’s
favorite listening position, minimizing
reflections from the side walls. For surround
sound or low volume background listening
create more reflections and thus more
ambience by directing the tweeter towards
the side walls.
Removing the Grilles:
To remove the grille from the LSC-8, 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-8 grille 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.
OPERATION
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.
