The L820 loudspeakers are  
designed to be oriented hori-  
zontally, as shown in the illus-  
trations below. Although these  
loudspeakers are designed as  
a mirrored pair, the decision  
as to which one is left or right  
will depend on the amount of  
space left between them.

tions for the pilot holes. Install  
the loudspeaker by slowly  
moving the cabinet toward  
the screws so that the screw-  
heads clear the larger circu-  
lar portion of the two key-  
holes. Once both screwheads  
have entered the keyholes,  
the loudspeaker should gently  
be lowered onto the screw  
shafts. Check that the loud-  
speaker is firmly locked onto  
the screws by gently pulling the  
speaker down and forward.  
• Proper selection of mount-  
ing hardware and installation  
of the wall brackets are the  
responsibility of the customer.

• This product is not intended  
for ceiling mounting.  
See Figure 1. The holes  
should be 2-1/4" (57mm)  
Two Number 8 roundhead or  
panhead screws should be  
used for each loudspeaker.  
The screwhead should be  
between 5/16" (8mm) and 1/4"  
(6.3mm) in diameter, and the  
screw should be at least 2"  
(50mm) in length.  
below where you want the  
top of the enclosure to be  
positioned. Use a carpenter’s  
level to ensure that the holes  
are even and that the speaker  
will mount on the level.  
Install the two screws into  
either a wooden wall stud or  
anchor, and tighten them until  
the back of each screwhead  
is about 1/8" (3mm) from the  
wall. See Figure 2.  
Fig. 1  
Fig. 2  
When installing screws in any  
wall, it is always preferable to  
screw them into a wall stud. If  
none is available, it is impor-  
tant to always use properly  
selected wall anchors.

Models L810 and L820 may  
also be corner-mounted using  
the keyholes located on the  
bezeled corners. For corner  
mounting, fold the mounting  
template in half, place the  
fold in the corner at the  
desired height, and use the  
outer holes. If the template is  
missing, for corner mounting  
drill each pilot hole 7-3/4"  
(197mm) from the corner for  
model L810, or 9-11/16"  
(246mm) from the corner for  
model L820. However, if your  
corner is not precisely 90  
degrees, these measure-  
ments may not work. In that  
case, it is recommended that  
you contact a professional  
custom installer, who can  
determine the correct loca-  
Attach two of the four self-  
adhesive rubber pads that  
came with the loudspeaker to  
the back of the enclosure in  
the two bottom corners so  
that the cabinet is spaced  
evenly from the wall. Select a  
suitable mounting location on  
a wall. (The ceiling is not a  
suitable mounting location.)  
Drill two pilot holes, appropri-  
ately sized for the specific  
self-tapping screw or wall  
anchor that you will be using.  
A template is included with  
your loudspeaker that indi-  
cates the proper locations for  
the pilot holes. In the event  
that the template is missing,  
refer to this chart:

TROUBLESHOOTING  
If there is no sound from  
any of the speakers:  
• Check that receiver/ampli-  
fier is on and that a source is  
playing.  
• Review proper operation of  
your receiver/amplifier.  
If there is no sound  
coming from one  
If there is no sound from  
the surround speakers:  
• Check all wires and con-  
nections between receiver/  
amplifier and speakers.  
Make sure all wires are con-  
nected. Make sure none of  
the speaker wires are frayed,  
cut, punctured or touching  
each other.  
• Review proper operation of  
your receiver/amplifier and  
its surround sound features.  
• Make sure the movie or TV  
show you are watching is  
recorded in a surround  
sound mode. If it is not,  
check to see whether your  
receiver/amplifier has other  
surround modes you may  
use.  
• In Dolby Digital or DTS  
modes, make sure your  
receiver/processor is config-  
ured so that the surround  
speakers are enabled.  
• Review the operation of your  
DVD player and the jacket of  
your DVD to make sure that  
the DVD features the desired  
Dolby Digital or DTS mode,  
and that you have properly  
selected that mode using both  
the DVD player’s menu and the  
DVD’s menu.  
nel, the source of the prob-  
lem is most likely with your  
receiver or amplifier, and you  
should consult the owner’s  
manual for that product for  
further information. If the  
problem has followed the  
speaker, consult your dealer  
for further assistance or, if  
that is not possible, visit  
information.  
speaker:  
• Check the “Balance”  
control on your receiver/  
amplifier.  
• Check all wires and con-  
nections between receiver/  
amplifier and speakers.  
• Make sure no wires are  
touching other wires or  
terminals and creating a  
short circuit.  
If the system plays at  
low volumes but shuts  
off as volume is  
increased:  
• Check all wires and con-  
nections between receiver/  
amplifier and speakers.  
• Make sure all wires are  
connected. Make sure none  
of the speaker wires are  
frayed, cut or punctured.  
• If more than one pair of  
main speakers is being used,  
check the minimum imped-  
ance requirements of your  
receiver/amplifier.  
• Make sure all wires are  
connected. Make sure none  
of the speaker wires are  
frayed, cut or punctured.

• In Dolby Digital or DTS  
modes, make sure that the  
receiver/processor is config-  
ured so that the speaker in  
question is enabled.  
If there is no (or low)  
bass output:  
• Turn off all electronics and  
switch the speaker in ques-  
tion with one of the other  
speakers that is working cor-  
rectly. Turn everything back  
on, and determine whether  
the problem has followed the  
speakers, or has remained  
in the same channel. If the  
problem is in the same chan-  
• Make sure the polarities  
(+ and –) of the left and right  
“Speaker Inputs” are  
connected properly.  
• Consider adding a powered  
subwoofer to your system for  
use with digital “.1” surround  
formats.
