8. Install the baffle

Now we need to connect the output wires from the crossover to the terminals on the drivers and place the baffle
into the cabinet. With the baffle leaning against the cabinet, make all driver connections, once again paying
attention to the polarity of the connections. The red wires will attach to the terminals that are marked with a red
color or with a + sign.

The baffle can now be installed into the cabinet, working carefully to make sure no wires are trapped between the
baffle and the cabinet. Once the baffle is fully installed, it can be secured via the included machine screws and
glued into place if desired. Using the 4 machine screws by themselves will have adequate holding power to
prevent leaks and vibrations of the baffle. However, for the utmost cabinet strength, the baffle should be glued
into place with polyurethane glue. Note: Once the baffle is glued into place, making any changes to the speaker
becomes very difficult. Please listen to the speakers for a period of time with just the machine screws holding
the baffle in place to make sure everything is working correctly before you secure the baffles permanently.

Note: Makes sure that both baffles are installed in the same oeientation; the 3 holes on the tweeter means the
baffles are not vertically symmetrical

9. Install Grill

Attaching the speaker grills is the last step in the assembly procedure.

The grills themselves should come with the male guides already installed. If they are not installed, they should
be tapped into place with a hammer, using a small socket or similar object placed around the male projection.
The socket will protect the male pin, while applying uniform pressure around the mounting flange. It is best to
install the guides with the grills laying flat on a solid surface to minimize the chance of installing the guide
askew.

The female guides are designed to fit into the recesses where the screws attach the baffle to the cabinet. They
can be tapped into place with a hammer, being careful not to damage the finish on the front baffle. Note: It is
difficult to remove the female socket once it is installed, so all testing should be done before the sockets are
installed. If you need to remove the sockets, they will likely be damaged in the process. Replacement guides are
available if necessary.

Once the guides are in place, the grill can simply be pressed onto the front of the cabinet.

10. Care and cleaning

To protect the finish of your Parts Express speaker system, it is important to use some care when it comes time
to clean them. To remove dust from drivers, grills, or the cabinet tops, a synthetic “feather duster” works well. For
more stubborn dust on the grills or woofers, a vacuum cleaner with gentle brush attachment may be used. It is
not recommended to use any type of cleaning apparatus on tweeter domes; dust will not affect the sound, and
the chance of damaging the dome is high.

For cleaning streaks or fingerprints on the cabinet finishes, an ammonia-based window cleaner is recommended.
It will not affect the finish and will leave a streak-free shine. It is important to use only very soft, clean cloths,
and to wipe gently at the surface. Intense scrubbing or using cloths with debris on them may cause small swirl
marks or scratches. Of course, the best way to maintain the finish on the cabinets is to prevent soiling them in
the first place. Never place drinks or abrasive objects on the top of the speakers.
