8. SERVICE and MAINTENANCE

Maintenance

Usually, your EAW Commercial loudspeaker will not require regular maintenance for 

normal use. However, you can do several things to keep your loudspeaker in good operating 

and cosmetic condition.

•  Testing: Periodically test your loudspeaker for proper performance. A simple test is 

to play a CD through it using well-defined, articulate, wide-range program material. 

Listen to ensure all drivers are working properly and for any evidence of distortion or 

other extraneous sounds. Test at several volume levels: very low, normal, and high.

•  Mounting/Rigging: Any mounting or rigging hardware should be regularly inspected 

for security, wear, deformation, corrosion, and any other circumstances that may 

affect the load-handling capability. Immediately remove from service and replace any 

hardware whose load-handling capability may be compromised. 

•  Cleaning: Cleaning the exterior of the enclosure will depend on the type of “dirt.” 

Dust, food spills, or similar contaminants can usually be removed with a cloth 

dampened with water, or a mild household cleaner. Avoid using any strong solvents 

as this may damage the finish. Turn the amplifiers off before cleaning.

•  Scratches or Dents in Wood Enclosures: Minor scratches on the enclosure can be 

painted over with an outdoor latex paint, or simply a colored in with a “Sharpie” or 

artist’s marking pen. More serious gouges or dents should be sanded out, filled with 

wood putty, and repainted. Touch-up paint in pints and quarts is available through 

EAW Commercial Technical Support.
