Appendices

7.1 Appendix A — Painting the Speaker
If the speaker is installed in an area where the interior design requires a color match, these
speakers are simple to paint. The speakers can accommodate almost any type of latex or oil-
based paint. The bezel/rim can be painted before installation or after mounting into the
ceiling.
Painting Process
Clean the rim and grille with mineral spirits or other light solvent. Do not use harsh solvents
such as gasoline, kerosene, acetone, or other chemicals. If you use these cleaners you may
permanently damage the enclosure. Also, don't use abrasives products such as sandpaper or
steel wool.
Either by rolling or spraying, apply two or more thin coats of paint. If you are spraying, hold
the spray can at the angles shown in Figure 21.

If you are painting the grille also, you must first remove the internal grille cloth. Spray painting
is strongly recommended. If the grille is rolled or brush painted, the grille may become
clogged with paint and the sound quality will suffer. After the paint has dried, replace the
internal grille cloth.
If you wish to paint the speaker along with the ceiling after installation, insert a plastic or
cardboard paint shield into the front of the speaker to mask the drivers and internal baffle,
paint the speaker, and then remove the shield. Do not paint the steel back can.
