INSTALLATION
PREPARING FOR
INSTALLATION
Installation Existing
Construction:
If you are installing LST speakers into an
existing wall, take time to consider any
possible obstructions, which may be hidden
inside the wall: studs, electrical wiring,
telephone wiring, plumbing, AC or heating
conduit and ductwork.
1. Using your stud locator, identify the
location of the studs on each side of the
proposed speaker mounting location.
2. Mark their edges, using masking tape.
3. Repeat this process for the other
speakers.
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 wall. Choose a suitable mounting
height, and then line up both speakers
approximately the same distance from the
sidewall and ceiling boundaries.
4. You may have to adjust the speaker
mounting locations based on how
symmetrical the studs are located, in the
wall space.
5. Check for clearance using the following
method.
a. Drill a 1/4” pilot hole in the center of the
intended speaker location.
If you are installing the speakers into a new
construction wall, follow the above
recommendations and install the new
construction speaker bracket.
b. Cut a foot-long piece of coat hanger.
c. Bend the wire, creating a right angle,
leaving 4-1/4” at one end.
Label the speakers wires at the
amplifier location.
d. Poke the “L-shaped” wire into the pilot
hole and turn it in a complete circle,
checking for obstructions.
e. Push it into the wall cavity to make
sure you have approximately 4” of
depth.
f. If the coat hanger movement is
obstructed by anything, fill the hole(s)
with spackle and try another location
2
6. Locate the cutout template.
13. Tightly twist the end of each wire until
no frayed ends remain.
7. Use a pencil and the cutout template to
trace the speaker outline in the desired
locations on the wall.
14. Attach the speaker wires to the speaker
terminal connectors. Connect the
negative output from the amplifier to the
black terminal. Connect the positive
output from the amplifier to the red
terminal.
8. Use a drywall saw to cut along the
penciled line.
9. Slip the mounting bracket through the
opening and pull it toward you so that its
front edge slides into the hole and stops
in place.
15. Set the speaker configuration switches
on the rear of the speaker (see Setting
the Speaker Configuration Settings).
10. Attach the frame to the bracket by
screwing the frame to the bracket using
the supplied screws. NOTE: Do not over
tighten the screws, this will distort the
frame and the grille will not fit.
16. Install the speaker in the frame. Screw
the enclosed self-tapping screws into
the dimples of the speaker baffle as
shown in Figure 2.
17. Repeat steps 1-16 for each speaker
being installed.
11. The screws should pull the frame and
bracket together (sandwiching the
drywall) so that the frame is flush with
the wall surface.
18. After making tonal adjustments on all
speakers (see Setting the Speaker
Configuration Settings), install the grill
into the speaker.
12. Strip 1/4” of insulation from the end of
each wire.

Installation New Construction:
8. In unique situations where the bracket
must be located precisely next to a joist,
the bracket has “emergency” screw
holes located on its snap-on tabs. Break
away two of the outer mounting tabs on
the side you wish to affix, see Figure 3.
Notching the joist so the bracket lies
flush may be required.
The speaker brackets should be installed
prior to the drywall.
1. Attach the wings to the bracket by
snapping them into the sides of the
bracket. (See Figure 1). To shorten the
wings, break them along the scored lines.
2. The wings and brackets have centering
lines to simplify placement of the speaker.
9. Next, screw the bracket tab to the joist
using one of the supplied screws.
Important: Do not over-tighten the screw,
doing so could crack the bracket tab.
Level the bracket, then affix the other side
of the bracket assembly using the
supplied screws.
3. Use a tape measure to locate and center
the brackets in the ceiling.
4. Mark each speaker location with a
pencil.
5. Screw one side of the assembled bracket
with wings to the joist using one of the
supplied screws.
10. After the drywall is installed, cut a hole
in the drywall using the outside of the
circular bracket flange as a template.
6. Screw the other side of the bracket/wing
assembly to the joist. Two screws on
each side make for a very secure
installation.
11. Attach the frame to the bracket by
screwing the frame to the bracket using
the supplied screws. NOTE: Do not over
tighten the screws, this will distort the
frame and the grille will not fit.
7. Secure the wire to the bracket using the
bracket’s wire tie.

12. The screws should pull the frame and
bracket together (sandwiching the
drywall) so that the frame is flush with
the wall surface.
LST-RLS Main/Surround Switch
The crossover on the back of the LST-RLS
enables you to configure the speaker for
best performance as either a front “main”
speaker or rear “surround” speaker. When
the LST-RLS is used as a surround speaker,
set the switch to the “Surround” position to
provide a diffuse sound field which provides
a more convincing illusion of sound all
around the listener. When configured as a
surround speaker, the orientation of the
tweeter is no longer critical.
13. Strip 1/4” of insulation from the end of
each wire.
14. Tightly twist the end of each wire until
no frayed ends remain.
15. Attach the speaker wires to the speaker
terminal connectors. Connect the
negative output from the amplifier to the
black terminal. Connect the positive
output from the amplifier to the red
terminal.
Front Baffle Switches
LST-CTR Acoustic Fine Tuning
The front-mounted switches on the LST-CTR
enable the speaker to be optimized
regardless of positioning or room acoustics
by providing 3dB of Treble Cut and 3dB of
Dialog Enhancement. Start by listening to
the speaker in the normal mode (switch is in
the “out” position). If the sound seems to
have too much treble, depress the switch
labeled Treble Cut to reduce the amount of
high frequencies.
16. Set the speaker configuration switches
on the rear of the speaker (see Setting
the Speaker Configuration Settings).
17. Install the speaker in the frame. Screw
the enclosed self-tapping screws into
the dimples of the speaker baffle as
shown in Figure 2.
18. Repeat steps 1-17 for each speaker
being installed.
If you desire to make dialog more
pronounced, depress the switch labeled
Dialog Enhance.
19. After making tonal adjustments on all
speakers (see Setting the Speaker
Configuration Settings), install the grill
into the speaker.
LST-RLS Acoustic Fine Tuning
The front-mounted switches on the LST-RLS
also enable the speaker to be optimized
regardless of positioning or room acoustics.
They provide 3dB of Treble and Bass Cut
respectively. Start by listening to the
speaker in the normal mode (switch is in the
out position). If the sound seems to have too
much treble, depress the switch labeled
Treble Cut to reduce the amount of high
frequencies. If the sound has too much low
frequency output (because it is placed near
a corner perhaps) depress the switch
labeled Bass Cut.
SETTINGTHE SPEAKER
CONFIGURATION SETTINGS
Crossover Mounted Switches
LST-CTR OAC Switch
The crossover on the back of the LST-CTR
enables you to defeat the Off-Axis
Compensation (OAC) feature. Defeat OAC
when the speaker is mounted at ear level
directly in front of the primary listening
position, as would be the case when the
speaker is mounted behind a perforated
projection TV screen.

REMOVAL OF GRILLE
Removing the Grille
OPERATION
Listening at Higher Volumes:
Listening at Higher Volumes:
If the grille is already installed, remove it by
using a bent paper clip or the tip of a
corkscrew and pulling it away from the
frame. See Figure 4.
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
less likely to produce any clipping distortion.
Figure 4
PAINTINGTHE GRILLE
AND FRAME
Painting the Speaker Frame
The speakers must be removed prior to
painting the frames.
Painting the Grilles:
The 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.
