If you are using an applicator or brush and a can of paint, thin the paint first.
Thick paint will tend to clog the grill holes.
Replacing the Grill
Carefully fit the grill into its recess so that it is barely in place. Starting with one
corner, go around the speaker, pushing the grill in a little bit each time. You
should be gentle, the aluminum grill can be easily bent out of shape. You will
feel a positive “snap” when it is fully in place.
2. Wipe off the other sides of the cabinet, the bracket, bracket knobs, and grill
with a damp cloth. Do not touch or rub the speakers on the front baffle. Make
sure everything is dry before masking.
3. Mask off the binding posts and the brass threaded inserts on the back panel
with masking tape.
4. Mask off the threaded inserts on the top and bottom with masking tape.
5. Protect the front of the speakers by inserting the supplied paint masks in
place of the grills.
Painting the Cabinet, Bracket Knobs and Bracket
1. Apply two thin coats of a primer to the cabinet and knobs. We recommend
Krylon Sandable Spray Primer #1318. The bracket doesn't require a coat of primer.
2. Allow the primer to completely dry.
3. Apply the finish color.
4. Allow the paint to completely dry.
5. Carefully remove the masking material.
6. Do not reattach the speaker to the bracket until the bracket is mounted. Try
to keep all handling of the freshly painted parts to a minimum.
Painting the Grill
The grill is important to the sound of the OS-20. Do not fill the holes of the grill
with paint. The grill is constructed of aluminum with a perfectly even powder
coat overall. This powder coat is an ideal primer.
If you are using a spray paint, use two thin coats without any primer. If you are
using a compressor and a spray gun, use the finest, most diffuse setting. Practice
on paper if you are not experienced in painting with spray paint.
