Steps to Installing

Painting the grille

It is important to prevent paint from clogging the grille perforations, which can adversely affect performance. You can use a dry brush technique or choose to spray paint the grille. Do not use a paint roller, however.

Regardless of the technique you choose:

Remove the grille from the speaker if it has been installed.

Before you begin to paint, clean the grille to remove possible contaminants. Even finger- prints can prevent uniform coverage.

Check to be sure the paint is distributed evenly and covers the grille thoroughly. If not, you may need to paint the inside of the grille to fix the problem.

When it is dry, protect the painted grille with clean cloth or tissue paper until you attach it to the speaker.

Using a dry brush technique

Unthinned latex paint is appropriate for this method. Be sure to put down enough paper to cover your work area and allow for repeatedly blotting the brush.

1.Dip the tip of a clean, dry brush in the paint.

2.Stroke across the paper to reduce the amount of paint on the brush. When you can see individual bristle marks, the brush is ready to use on the grille.

3.Stroke lightly back and forth on the front of the grille, in a horizontal direction, until you need more paint.

Tip: If paint clogs any of the grille perforations, try angling your stroke to unclog it, or blow gently on the clog.

4.Repeat the above steps until the outside of the grille is completely covered.

5.Turn the grille 180˚ and repaint the entire surface using back-and-forth strokes again.

Using a spray technique

Latex or oil-based architectural paint requires thinning for use with a siphon-feed spray gun set for 30 psi (2.1 bar) and for application in a 3- to 5-inch (7.6-12.7 cm) fan pattern. The thin- ning formula depends on the type of paint you are using.

Thin vinyl acrylic latex paint as follows:

To 6 parts of paint, add 3 parts of water and mix thoroughly. Add 1 part of denatured ethyl alcohol (which breaks down paint particles so they do not clog the grille) and mix again.

For use of architectural or automotive paints:

This type of paint should be used by a professional with the right equipment and technique. This paint must also be thinned, using a solvent.

For use of lacquer or enamel spray paint:

This comes in an aerosol can and needs no further thinning.
