• Proper selection of mounting
hardware and installation of
the wall brackets are the
responsibility of the customer. 

• This product is not intended
for ceiling mounting.

Two Number 8 round-head or
pan-head screws should be
used for each loudspeaker.
The screw head should be
between 5/16 inch (8mm) and
1/4 inch (6.3mm) in diameter,
and the screw should be at
least 2 inches (50mm) in
length.

When installing screws in any
wall, it is always preferable to
screw them into a wall stud. If
none is available, it is
important to always use
properly selected wall
anchors. 

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,
appropriately sized for the
specific self-tapping screw or
wall anchor that you will be
using. A template is included

with your loudspeaker that
indicates the proper locations
for the pilot holes. In the event
that the template is missing,
refer to this chart:

L810

152mm (6") 

L820

216mm (8-1/2") 

LC2

368mm (14-1/2") 

See Figure 1. The holes
should be 57mm 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 screw head
is about 1/8" (3mm) from the
wall. See Figure 2. 

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. In case 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 measurements
may not work. In that case, it
is recommended that you
contact a professional custom
installer, who can determine
the correct locations for the
pilot holes. Install the
loudspeaker by slowly moving
the cabinet toward the
screws so that the screw
heads clear the larger
circular portion of the two
keyholes. Once both screw
heads have entered the
keyholes, the loudspeaker
should gently be lowered onto
the screw shafts. Check that
the loudspeaker is firmly
locked onto the screws by
gently pulling the speaker
down and forward.

CAUTION: Floorstanding
(tower) loudspeakers have a
high center of gravity and may
become unstable and tip over
during earthquakes, or if
rocked, tipped or improperly

positioned. If this is a concern,
these speakers should be
anchored to the wall behind
them, using the same
procedures and hardware
customary for anchoring

bookcases and wall units. The
customer is responsible for
proper installation and proper
selection of hardware.
