Painting the Bezel and the Grille
The bezel of the speaker assembly and the metal grille may be left as is or painted to match your décor. You can
paint the frame before or after it is installed in the wall. Use the included paint shield to protect against getting
any paint on the front of the speaker. Spray painting (using slightly thinned paint) is the best method to use for
painting the grille. If you paint the grille use air pressure to “blow out” any grille holes that become covered over
with paint. Be sure to use paint labeled safe for plastics. Many spray paints intended for use on wood and metal
contain solvents that are harmful to plastics and may damage the speaker assembly. Also, do not attempt to
clean any plastic parts of the speakers with solvents or any petroleum based products.
