Painting the Grille -- Control 300 Series Grilles feature a powder coated, satin finish paint (RAL 9016 - Pantone equivalent 11-0602TPX) and can be painted to match any decor. This should only be done when the grilles have been removed from their loudspeaker and back box / can assembly.
For best results, a spray paint technique is recommended. If the grille is rolled or brush painted, the grille perforations may become clogged with paint and poor sound quality may result.
Maintenance -- No maintenance is required when assembled in accordance with the instructions and wiring guidelines described in this manual.
