Height  
Try to place the speakers so they are close to the same height as your ears when you are seated in the  
preferred listening area. Also be sure the speakers are high enough that the sound they produce will  
not be constrained by  
Separation  
Start at your preferred listening position with the speakers at the points of an equilateral triangle, aimed  
toward the listening position. (See diagram.) Experiment with moving the speakers closer together and  
varying the aiming angle until you get the stereo image you prefer.

Speaker orientation  
Stereo imaging is generally best when a speaker’s long axis is vertical, but horizontal placement is by  
no means ruled out. Try the speakers both ways to determine if the difference in sound is important  
to you.  
Any of the a/d/s/ mini-speakers can be placed on a shelf or other solid surface. If the speakers are placed  
on a shelf, put the supplied adhesive-backed felt pads on the bottom of the cabinets. The pads protect  
the surface under the speakers and reduce the possibility of rattles or buzzes. The L210 and L310 may  
also be used freestanding.  
mounting the speakers  
Before mounting the speakers in brackets, plan the mounting location and method very carefully. Follow  
the speaker placement guidelines described in the instruction manual and decide on the mounting  
locations. If you plan to hide the speaker wires behind the mounting surface, route the wires before you  
mount the brackets. See the following section for information on wiring.

How the brackets should be fastened to the mounting surface depends on the structure and material  
of the mounting surface. There are two typical situations. One is with the brackets attached to a  
conventional wall constructed with drywall material over wood studs. The other situation is with the  
brackets mounted to a wood cabinet or some other solid material. When the speakers are mounted on  
drywall the plastic screw anchors will be used in conjunction with the screws. When the speakers are  
mounted on a solid panel the screws anchors will not be needed. Driving the screws directly into the  
solid panel will provide a strong enough mounting.  
The L-series speaker system is supplied with brackets for horizontal or vertical mounting. Pick the  
correct bracket for your application, and set the bracket in the installation location. Be sure it is  
straight. Using the bracket as a template, mark the location of the two mounting screw holes. Set the  
bracket aside. If the plastic anchors will be used drill the holes for them with a 1/4" bit. If only the self  
tapping screws are used, drill pilot holes with a 1/8" bit. Push the plastic screw anchors, if they are  
being used, into the holes drilled for them. NOTE: If the speakers are being mounted horizontally the  
opening in the end of the mounting brackets should be oriented upward.

Drive the mounting screws through the bracket, into the holes, until they are firmly set. Connect the  
wire to the speakers (see wiring tips in following section). Set the speakers in the mounting brackets,  
placing a rubber washer between the speaker cabinet and the bracket on each side. Secure the cabinet  
to the brackets with the threaded knobs, placing a second rubber washer around the threaded part of  
each knob. Position the speaker as desired, and tighten the knobs.  
wiring  
Wire  
Use two-conductor stranded-type, insulated wire to connect the speakers to the amplifier. Lamp” wire  
or “zip cord” works well. If you are running wiring within the walls, make sure that it complies with  
your local building codes pertaining to low-voltage wiring. Use at least 16 gauge for runs of less than  
50 feet. Use 14 gauge or larger wire for longer runs. The resistance of 18 gauge or smaller wire can  
cause a bass response peak if used for more than a few feet.  
Preparing the wire  
Estimate the amount of wire needed. Allow enough extra wire so you can move the speakers if  
necessary. Separate the conductors of each wire pair a few inches in from the end. Strip about 3/8”  
insulation from each conductor. Be careful not to cut into the wire itself. Twist the strands of the  
conductor together to avoid fraying. For outdoor use, terminate the wire with gold-plated pin-type  
terminals and insulate the wire-to-pin connection with silicone filled heat-shrink tubing. Bare copper  
wire can corrode and cause unreliable connection over time.  
Polarity  
The polarity - the positive/negative orientation of the connections - for every speaker-to-wire and wire-  
to-amplifier connection must be the same so the speakers will be “in phase”. If the polarity of one  
connection is reversed, bass output is reduced and stereo imaging is degraded. All wire is marked so  
you can identify the two conductors. There may be ribs or a stripe on the insulation of one conductor.  
The wire may have clear insulation with different color conductors (copper and silver). Decide which  
conductor you will use for “positive” and which for “negative”. Then be consistent with every speaker-  
to-wire and wire-to-amplifier connection.  
Speaker input connectors  
The speakers have color coded push-to-connect input terminals that accept virtually all types of speaker  
wire. Push the back of the terminal to open the wire access hole. Put the stripped wire or pin terminal  
into the hole and release the terminal.  
Making the connections  
Connect the positive conductor of one wire to the red input connector of one speaker and to the red  
or “+” speaker output connector of the associated amplifier channel. Connect the negative conductor of  
the wire to the black terminal of the speaker and to the black or “-” connector of the associated  
amplifier channel. Repeat the procedure for the other channel. Be sure to follow exactly the same  
connection procedure for both channels.  
speaker protection  
The speakers have a solid-state, fully automatic tweeter protector. This device reduces the power to the  
tweeter when the speaker is operated at unsafe power levels. The protector resets itself when power  
is reduced to a safe operating level. If high power operation causes the tweeter to stop playing, turn  
down the volume control until normal sound resumes. Note: The tweeter protector provides a significant  
level of protection. However it does not guarantee that the tweeter cannot be damaged. Always be  
careful when operating the speakers at a high volume level.

maintenance  
The drivers require no routine maintenance. Do not let anything touch the drivers. Do not vacuum clean  
the drivers or front panels of the speakers. Some dust accumulation on the drivers is normal and does not  
affect the sound in any way. Heavy dirt buildup may be carefully removed with a soft paintbrush if  
necessary.  
The enclosures of your a/d/s/ speakers require no maintenance other than dusting. Dust the speakers  
with a dry or slightly damp cloth. To clean the grills, remove them from the speaker and vacuum them.  
Do not vacuum the grille while they are on the speakers.  
Most difficulties with high fidelity equipment result from loose or poor connections, bad  
connecting cables or switches in the wrong positions.  
No sound It is rare for a speaker to fail completely. When there is no sound, check all the speaker wire  
connections and the setting of the amplifier’s tape monitor or speaker selector switch.  
Dull or muted sound Operating the speakers at an unsafe power level activates the automatic tweeter  
protector. Turn down the amplifier volume control and the protector will automatically restore signal to  
the tweeter. Also check the amplifier’s tone controls or “high filter” switch.  
Distorted Sound Distortion at moderate levels can be caused by loose connections, or stray wire strands  
shorting out adjacent wires at the amplifier or speaker terminals. If you hear distortion or any type of  
buzzing or rattling sound from an individual driver, contact your a/d/s/ dealer. Distortion at high levels  
is the result of either reaching the power limit of the amplifier or of the speaker. Turn down the volume  
to prevent damage.  
Noise or Hum Continuous background noise or hum are always from the electronic equipment and not  
from the speakers.
