Painting the speakers, Before installing

Painting the speakers

While the speaker and grille can be painted after it is installed, painting it beforehand is much easier.

It is recommended to use spray paint, as brushed paint may clog the holes in the grille and reduce the sound quality significantly.

1Remove the fabric scrim from the inside of the grille.

Carefully peel off the fabric scrim and lay it down flat so as not to get it wrinkled.

2Use the supplied paint mask to cover the speaker. If you don’t have the paint mask, use paper and masking tape.

3Paint the speaker and grille the desired color.

As previously mentioned, it is strongly recommended that you paint before installation and that you use spray paint.

4After the speaker and grille have dried completely, remove the paint mask and carefully replace the fabric scrim on the back of the grille.

Before installing

•Before installing the speakers, run the speaker cables to the installation location.

•To maximize sound quality, choose the correct speaker gauge cables from the table below.

If the resistance of the speaker cable is too high, the signal will be attenuated and the speakers’ frequency response will be degraded.

How to install

Make sure you have read and understood all the information above, For the installer on page 3 and Before installing above.

1Once you have decided on the installation location, prepare the supplied template.

Cut out the inside of the template along the dotted line and discard the inner section.

2Attach the template (outer section) to the wall/ ceiling using tape.

Make sure the template is aligned properly.

3Trace a line onto the wall/ceiling, following the inner perimeter of the template.

4	Cut a hole where you have drawn the outline.
Be careful when cutting the hole, and use a proper
cutting tool.
5	Pull the speaker cable through the hole that has
been opened.
Be careful not to apply to much force when pulling on the
speaker cable or bend the cable at sharp angles.
6	Connect the cable wire to the speaker as shown
below.

When connecting the speakers, be careful not to touch

the diaphragms of the drivers.

Twist and pull off the protective shields on each wire.

Insert the speaker cable wires into the holes while pressing down on the terminal posts on the speaker, and then release the terminal posts. For input terminal polarity, red is positive (+) and black is negative (–).

•After connecting the wires, pull lightly on them to make sure that the ends of the wires are securely connected to the terminals. Poor connections can create noise and interruptions in the sound.
