SPK-C611 - Installing the Open-back Ceiling Speakers 

 

5.  Insert the speaker into the opening and tighten the screws. 

When tightening the screws, the tabs automatically turn outward, thus 
clamping the speaker to the wall from its rear side. 

 

Do not over-tighten the screws. It may cause damage to both the 
speakers and the surface. 

6.  Push the grille firmly into the slot in the speaker baffle.

 

Check that the grille is securely seated. 

To remove the grille, insert two bent paper clips into the holes in the grille and carefully 

pull it down. Repeat this around the perimeter of the grille until it is completely removed 

5.4 

Painting the Speaker 

You can paint the speakers before or after the speakers are installed. When 
painting before installation: 

 

Clean the rim and grille with mineral spirits or other light solvent that is 
unlikely to damage the surface 

 

Spray with color by holding the spray can at an angle of 45

°

 

 

When spraying the grille, take care not to clog the holes in the grille 
as this will greatly reduce the sound quality of the speakers. 

When painting after installation: 

 

Use the circle that you cut out of the template as a paint mask 

 

After you finish painting, remove the paint mask
