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 be used when  
installing into 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 loud-  
speaker perfect for moist environments.

PACKAGE CONTENTS  
If you are installing the speakers into a new  
ceiling follow the above recommendations and  
install a set of JobSite NCB-6 Ceiling Brackets,  
prior to the drywall being installed.  
Speakers x 2  
Speaker grilles x 2  
Speaker cutout template / paint mask x 1  
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.  
PREPARING FOR INSTALLATION  
If you are installing the LSC-BG 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.  
TOOLS REQUIRED  
Stud Locator (for existing construction)  
Drywall saw (for existing construction)  
Pencil (for existing construction)  
Cordless screwdriver with No2 Philips bit  
Wire stripper  
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,  
Wire labels  
or a light fixture.

9. Strip 1/4” of insulation from the end of  
each wire coming from the amplifier.  
INSTALLATION  
Installation Existing Construction:  
10. Tightly twist the end of each wire until no  
frayed ends remain.  
1. Use a stud locator to identify the location  
of the ceiling joists on each side of the  
proposed loudspeaker mounting location.  
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.  
2. Mark ceiling joists’ edges, using  
masking tape.  
3. Repeat this process for the other  
loudspeaker locations.  
12. There are four clamps “dogs” which  
hold each speaker in place. Rotate all  
the dogs inward.  
4. You may have to adjust the loudspeaker  
mounting locations based on how the  
ceiling joists line up with the proposed  
speaker mounting locations.  
13. Insert the loudspeaker into the cutout in  
the ceiling.  
5. Check for clearance using the following  
method:  
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.  
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.  
d. Poke the “L-shaped” wire into the pilot  
hole and turn it in a complete circle,  
checking for obstructions.  
15. Install the grille into the speaker.  
16. Repeat this procedure for the next  
speaker.  
e. Push it up into the ceiling cavity to  
make sure you have approximately  
4” of depth.  
New Construction Installation:  
Install the proper ceiling bracket for this  
loudspeaker (NCB-6) using the instructions  
supplied with the bracket. After the  
hole is cut in the drywall per the bracket  
instructions, perform the following steps:  
f. If the coat hanger’s movement is  
obstructed by anything, fill the hole(s)  
with spackle and try another location.  
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  
painting the frame of the loudspeaker.  
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.  
7. Use a pencil and hole template to trace  
the hole outline in the desired location on  
the ceiling.  
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.  
8. Use a drywall saw to cut along the  
penciled line.

holes. Paint both sides of the grille to cover  
all the white paint.  
OPERATION  
5. Insert the loudspeaker into the cutout in  
the ceiling.  
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.  
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.  
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.  
8. Install the grille into the speaker.  
9. Repeat this procedure for the next  
speaker.  
SPECIFICATIONS: LSC-BG  
Removing the Grilles:  
Power handing:  
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.  
5 – 75 watts  
Frequency response:  
55Hz-20kHz +/- 4dB  
Impedance:  
8 ohms  
Dimensions:  
9-1/4” outside frame diameter  
Painting the Speakers:  
8” diameter hole cutout  
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.  
2-3/4” deep when installed in 1/2” drywall  
Ceiling Bracket for New Construction:  
JobSite NCB-6 (sold separately)  
Warranty: 5 year limited  
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
