OWNER’S MANUAL
LSB3
3-Channel Passive Soundbar

2
Congratulations and thank you for purchasing our Proficient Protege LSB3 Three-Channel Passive Soundbar!
This soundbar is designed to be used for the front left, center and right channels of a home theater system and
should be connected to the left, center and right channels of an A/V receiver or a multi-channel home theater
amplifier.
The LSB3 has three speaker enclosures within the soundbar. The Left and Right chambers are vented
enclosures and the Center chamber is a highly damped sealed enclosure. Because the Center Channel in a
home theater system gets nearly 70% of the audio, including most of the dialog, it needs to be particularly
accurate and intelligible. For this reason, Proficient chose to use a sealed box design for the LSB3’s Center
chamber for its lower group delay and more controlled excursion, which is engineering speak for enhanced
controlled woofers. The result is Center Channel dialog that is easier to understand with better clarity and
detail in the music.
Woofers and Tweeters
The LSB3 incorporates six injection molded graphite woofers and three silk dome tweeters. The woofers use a
special formulation of graphite, polypropylene and carbon fiber materials combined them using an injection
molded process. The qualities of these different materials work together to deliver exceptionally clear mid-
range as well as the stiffness and strength required to produce strong low frequencies that blend well with
any subwoofer.
The one-inch silk dome tweeters provide excellent off-axis response by nature of their dome shape, comple-
menting the dispersion of the woofers. The material properties of the IMG woofer cones and silk dome tweet-
ers work together to provide a seamless sound quality and a spacious, open sound that seems more like it’s
coming from three separate speakers instead of a soundbar.
Crossover Networks
The LSB3’s three internal crossover circuits (one per channel) are carefully tuned and thru our listening tests,
we believe that we have come up with a system that will deliver outstanding dispersion. That means all fre-
quencies of sound spread evenly around the room and the system has spacious, natural sound.
Surface Placement
The LSB3 soundbar can be placed on top of an AV rack, centered directly under the TV. Or, it can be placed on
a shelf that the TV sits on. Adhere the included feet to the bottom four corners to keep the LSB3 from vibrat-
ing on the surface it is placed on. The feet will also keep the soundbar from “walking” on the surface that it is
sitting on.
Wall Mounting
An included Proficient-designed mount makes it easy and quick to attach the LSB3 to a wall. It is designed to
screw into wall studs mounted 16 inches on-center, and allows you to slide the LSB3 horizontally so it lines up
perfectly with the center of the TV.
Bass
The graphite woofers deliver outstanding bass for their size, but the LSB3 isn’t designed to deliver true full-
range sound on its own. To get full-range sound, we recommend you combine the LSB3 with a Proficient floor
standing subwoofer when the budget and space permits.
Cabinet
Our cabinet is made from thick MDF panels to prevent unwanted vibration so the sound you hear comes
from just the drivers, not the cabinet. The black polymer coating helps to acoustically seal and dampen the
enclosure.
To get the best possible performance from your LSB3, please read this manual carefully and follow all instruc-
tions for installation and setup.
INTRODUCTION

Determine the Ideal Listening Zone
The area where the user will most likely be sitting when listening to the speakers is the Ideal Listening
Zone, and the LSB3 should be placed to optimize the sound for this seat. Ideally, the LSB3 (and the video
screen) should be centered on the same axis with the Ideal Listening Zone—i.e., the LSB3’s center tweeter
should be directly in front of your favorite listening seat. (Diagram 1)
The LSB3 should be mounted directly under the video screen, as close as possible to the bottom of the
screen. The soundbar should be centered horizontally with the video screen.

Using the Included Wall-Mount Bracket
The included wall-mount bracket makes it easy to attach the LSB3 to a wall built with standard 16-inch-on-
center studs. To mount the bracket, use a stud nder to locate the two wall studs closest to the horizontal
center of the video screen. Use a pencil or market to mark a point between these two studs and 6 inches
below the bottom edge of the TV chassis or projection screen.
Make sure there are no electrical wires, conduits, pipes or vents behind the spot you’ve marked. Use a ¼"
bit to drill a hole in the wall. Drill only as deep as needed to penetrate the wall. Insert the included wall
anchor and tap it in very gently with a hammer. Align the center mounting hole on the included mount
with the wall anchor, and secure it with the screw provided.
Use a spirit (bubble) level to assure that the mount is perfectly leveled, then use the four included long
screws to attach the mount to the wall. (Diagram 2) Make sure the screws go into the wooden studs
behind the wallboard. (Diagram 3) Attach the speaker wires to the soundbar, then lift the soundbar onto
the wall mount so the mount mates with the bracket mounted on the back of the speaker. (Diagram 4)
Press down lightly on the soundbar to make sure it’s rmly seated on the bracket. (Diagram 5) Now slide
the soundbar horizontally so it is centered with the video screen. (Diagram 6)

1. Use 16AWG (min) 2-conductor stranded speaker wire for speaker connection.
2. Strip approximately 1/2 to 3/4 of an inch off the ends and twist the strands together so there are no
loose ends that can cause shorts.
3. Depress the LSB3 speaker terminals as shown
in Diagram 7 so there is enough room to insert
the stripped wire without damaging the strands.
Once about half an inch of the wire is inside the
terminal, let go to secure the wire.
4. Connect the marked conductor of the cable (it may have a red jacket, or a white or blue stripe down the
side) to the +/red terminal of the speaker. Make sure each channel from the receiver or amp (left, center
or right) is connected to the correct channel of the LSB3.
5. Connect the other conductor of the cable to the -/black terminal of the speaker.
6. Repeat this process for all three of the LSB3’s internal speakers (left, center and right).
7. Connect the speaker wires to the appropriate +/red and -/black terminals on the receiver/amplier.
8. Conrm connection, polarity and position. Be sure all + and - are correct and that left, right, center and
surround speakers are connected to the proper terminals and positioned correctly. Improper position-
ing of multi-channel speakers will adversely aect system performance. (Diagram 8)

The finish on the LSB3 is a polymer coating that, while durable, should be carefully maintained. Do not
place any hard object directly on the cabinet without first putting down a soft cloth or other nonabrasive
pad. Do not place any liquid containers including drinks, flower vases or plants directly on the cabinet to
avoid water marks.
To clean the cabinet, use a feather duster to remove dust. Dust can be abrasive and wiping dust with a rag
can cause scratches. If additional cleaning is required, use a soft damp cotton cloth to clean the cabinet
surface. Do not leave any residual moisture on the cabinet surface.
