PRODUCT OVERVIEW  
The illustration shows how a  
typical JobSite LSC loudspeaker  
mounts into a ceiling.  
Ceiling Bracket serves as a “hole saver”  
when drywall has not been applied.  
Cannot use when installing loudspeaker in  
existing ceilings.  
Knockout wire tie allows the wire to be  
secured to the bracket throughout the  
new construction process. It knocks out  
cleanly when the speaker is installed.  
Wings instantly snap into  
the bracket without screws.  
Dogs swivel 90°, then  
clamp the speaker frame  
to the drywall.  
Frames are molded with a  
slight texture to assure good  
paint adhesion.  
Wings are scored for easy  
size trimming.  
Mounting screws tighten the  
“dogs”, clamping the speaker to  
the drywall.  
Brackets and wings attach to  
the ceiling joists with nails or  
screws.  
Rust-proof aluminum grilles make the loudspeaker  
perfect for moist environments. (LSC-5 ONLY)

PREPARING FOR  
INSTALLATION  
2. Mark ceiling joists’ edges, using masking  
tape.  
If you are installing the LSC-5/LSC-5R into  
an existing ceiling, take time to consider  
any possible obstructions which may be  
hidden inside the ceiling: ceiling joists,  
electrical wiring, telephone wiring,  
plumbing, AC or heating conduit and  
ductwork.  
3. Repeat this process for the other  
loudspeaker locations.  
4. You may have to adjust the loudspeaker  
mounting locations based on how the  
ceiling joists line up with the proposed  
speaker mounting locations.  
Determine the best mounting locations  
based on the room layout. Before cutting  
any holes, make sure the area behind both  
speakers is clear for installation. Speakers  
provide the best coverage, when centered  
in the room. Line up the speakers with a  
permanently mounted ceiling fixture such  
as can lights, or a light fixture.  
5. Check for clearance using the following  
method:  
a. Drill a 1/4” pilot hole in the center of the  
intended speaker location.  
b. Cut a foot-long piece of coat hanger.  
c. Bend the wire, creating a right angle,  
leaving 4-1/4” at one end.  
If you are installing the speakers into a new  
ceiling follow the above recommendations  
and install a set of JobSite NCB-5 Ceiling  
Brackets, prior to drywall installation.  
d. Poke the “L-shaped” wire into the pilot  
hole and turn it in a complete circle,  
checking for obstructions.  
e. Push it up into the ceiling cavity to  
make sure you have approximately  
4” of depth.  
Run speaker wire from each location to the  
amplifier location. Label the speakers wires  
at the amplifier end, so you know which  
wire goes to each speaker.  
f. If the coat hanger’s movement is  
obstructed by anything, fill the hole(s)  
with spackle and try another location.  
TOOLS REQUIRED  
6. Locate the hole template and remove the  
inside portion of it. The inside portion can  
be used as a paint mask, if you are

the ceiling.

9. Strip 1/4" of insulation from the end of  
each wire coming from the amplifier.  
3. Attach the speaker wires to the speaker  
terminal connectors. Connect the  
negative output from the amplifier to the  
black terminal and the positive output  
from the amplifier to the red terminal.  
10. Tightly twist the end of each wire until  
no frayed ends remain.  
11. Attach the speaker wires to the speaker  
terminal connectors. Connect the  
negative output from the amplifier to the  
black terminal and the positive output to  
the red terminal.  
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.  
12. There are four clamps “dogs” which  
hold each speaker in place. Rotate all  
the dogs inward.  
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.  
13. Insert the loudspeaker into the cutout in  
the ceiling.  
14. 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.  
7. Install the grille into the speaker.  
8. Repeat this procedure for the next  
speaker.  
Removing the Grilles:  
15. Install the grille into the speaker.  
To remove the grille from the LSC-5, 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.  
16. Repeat this procedure for the next  
speaker.  
Installation New Construction:  
Install the proper ceiling bracket for this  
loudspeaker (NCB-5) using the instructions  
supplied with the bracket. After the hole is  
cut in the drywall per the bracket  
For the LSC-5R, press your fingers against  
the inside of the grille’s white collar.  
While pressing against the collar, pull it  
towards you.  
instructions, perform the following steps:  
1. Strip 1/4" of insulation from the end of  
each wire coming from the amplifier.  
2. Tightly twist the end of each wire until no  
frayed ends remain.

Painting the Speakers:  
OPERATION  
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.  
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 very  
loud indeed before it produces any  
clipping distortion.  
Painting the Grilles:  
The LSC-5/5R 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.
