SPEAKER BREAK-IN
In the same way that a new car requires a break-in period before it can be safely operated
at high engine RPMs, speakers require a break-in period before they can be safely operated
at maximum volume levels. Proper break-in ensures that the moving parts of the speaker
(the cone and cone suspension) are allowed to flex and soften, losing the initial stiffness
and allowing the speaker to move through its full intended range. After the break-in
period, the speakers will produce richer and fatter sounding lows, warmer and smoother
sounding mids, and cleaner and more accurate highs, without any hint of distortion.
The best way to break-in speakers is simply to play normal music or watch movies at
moderate volume levels. The amount of time required for speaker break-in varies based on
the operating environment, but is typically in the area of 50~80 hours. It will take a bit
longer in a cold or dry environment and a little less time in a warm or humid environment.
Note that the break-in period does not have to be continuous.

SPEAKER WIRE PREPARATION
Before attempting to make any connections it is best to look at the situation, get all the
necessary materials together, and then make all the connections at once.
First, look at the back of your amplifier or receiver to determine what options it offers for
making connections. Amplifiers and receivers typically employ either 5-way binding posts,
spring-loaded terminals, or push terminals for the speaker connections.
A 5-way binding post can accept bare speaker wire, spade plugs, pin plugs, and banana
plugs, while spring-loaded terminals and push terminals can accept either bare speaker
wire or pin plugs. Refer to the documentation that came with your amplifier or receiver to
determine the maximum size/gauge speaker wire the speaker terminals can accept.
This speaker features spring-loaded terminals, which can accept pin plugs or bare wire up
to 14AWG. If your amplifier can accept it, you should use 14AWG speaker wire. Using pin
plugs is highly recommended for several reasons. Plugs are easier to connect, don't run the
risk of stray wire strands shorting the connections, allow for use of heavier gauge speaker
wire in most cases, and it is much easier to identify the polarity from a color coded ring on
a plug then from a subtle marking along the length of a wire.
Because the speaker wire will necessarily be run through your walls, you must use in-wall
rated wire. This is required by fire safety codes and ensures that the wire jacket will not act
as an accelerant in the event of a fire.
Rather than using a fixed length speaker wire, it is best to get a roll and cut the wire to the
length you need. This ensures that there is a minimum amount of excess wire.
Before making the actual connections, cut a length of wire to size. Note the markings on
the wire that differentiate between each conductor. Sometimes the marking clearly
identifies a positive and negative side. Some common clearly positive and negative
markings or identifiers are:
Positive
Negative
Red
Black
Copper
Silver
╋╋╋
━━━

In many cases, the mark is a single stripe on the jacket of one of the connectors. In this
case the side with the stripe is generally
considered the positive side, but it really does not
matter as long as you are consistent and always
using the stripe as positive or always using it as
negative.
When you are ready to prepare your speaker wire,
first separate about 4" of wire, then strip about
1/4" (6mm) insulation from the end and twist it to prevent stray strands. If you plan to use
banana or pin plugs (highly recommended), install the plugs on the wire.
PAINTING
The grille and frame can be painted to match your walls, making the speaker even less
noticeable. Perform the following steps to safely paint it without damaging the speaker.
1. Remove the center portion of the cardboard installation template/paint mask. The
central portion is the paint mask, while the outer portion is the installation
template.
2. Completely remove the grille by inserting a paper clip or the included grille removal
tool into one of the holes and pulling to lift it off the frame.
3. Remove the foam insert and set it aside.
4. Insert the paint mask, covering the
speaker while leaving the frame
exposed.
5. Paint the speaker frame and grille. It is
best to use spray paint to avoid paint
clogging the holes in the grille.
6. Allow the paint to completely dry before proceeding with installation. Ensure that
the holes in the grille are not blocked by paint.

INSTALLATION
Perform the following steps to install the speaker in the wall.
1. Determine where you will be installing the speaker. Use a stud finder to ensure that
there is sufficient space between the desired location and the adjacent studs. Be
sure and check for horizontal framing members, as well. Use a pencil to mark the
edges of the adjacent studs.
2. If you have not already done so, remove the center
portion of the cardboard installation template/paint
mask and set it aside. The central portion is the paint
mask, while the outer portion is the installation
template.
3. Position the installation template against the wall at
the installation location.
4. Use a carpenter's level to ensure that the template is
level.
5. Use a pencil to mark the cut line on the wall.
6. Remove the template from the wall and set it aside.
7. Use the level again to check the cut lines to ensure that they are level. Repeat steps
3-6 as necessary until the cut lines are level.
8. Drill a small hole in the middle of the cutout area. If the proposed installation
location is not clear, you can more easily repair the small hole than if you cut
without checking and find one or more obstructions.
9. Take a stiff piece of wire, such as a hanger, and bend it 90° about 8" from the end.
Insert the wire past the bend, then rotate the wire 360° to check for hidden
obstructions behind the wall. Push it in to ensure that there is sufficient clearance
behind the wall or ceiling.
10. Once you know your installation location is clear, use a drywall or keyhole saw to
cut along the cut lines.

11. If you have not already done so, prepare your speaker wire in accordance with the
guidelines in the Speaker Wire Preparation section above.
Important! Because the speaker wire will necessarily be routed through your walls,
you must use in-wall rated speaker wire.
12. Route your speaker wire from the back of your amplifier, through the wall, to the
installation location.
13. Connect the plastic spacers to the metal ring (flat
side) by lining up the protruding plastic with the holes
on the metal ring.
14. Remove the grille with the grille removal tool.
15. Place the metal ring around the back of the speaker
with the flat part of the metal ring facing the speaker.
The metal ring will only fit a certain way.
16. Thread the screws through the front of the
speaker and slightly into the metal bracket. At
this point, the screws should be flush and not
protruding through the threads in the bracket.
17. Connect one end of the speaker wire to the
speaker terminals.
18. Give a gentle tug on each lead to ensure that
they are securely connected to the terminals.
19. With the terminals at the bottom of the
speaker, slide the top part of the mounting
bracket into the opening and up, then slide the bottom of the metal bracket into
the opening
20. With the speaker flush against the wall, tighten the screws in an X pattern in
increments until they are all tight.
21. Replace the speaker grille.

22. Connect the other end of the speaker wire to your amplifier's speaker terminals,
taking care to match the polarity.
23. Plug in and power on your amplifier. Start audio playback and verify that the
speaker is operating properly.
Congratulations, your speaker is installed and ready for use!
