UNDERPOWERING VS. OVERPOWERING
Surprisingly, speaker damage can be caused by amplifiers with too little power.
An underpowered, overdriven amp sends heavily distorted, clipped audio to the
speakers. This can damage the high-frequency drivers. Clipping is usually audible;
it may vary from a harsh sound to a fuzzy or blurry sound. If you hear clipping
at loud volume levels, turn down the volume until the distortion is no longer
present.
On the other hand, overpowering a speaker can cause mechanical damage or
electrical failure by overstressing the speaker’s components. The speaker must
be powered appropriately to ensure its longevity and performance.
PAINTING
The speaker enclosure and grille can be painted with automotive paints or
spray paints specially designed to adhere to plastics. Perforated grilles require
special care when painting so that the holes do not become plugged with paint.
Applying several very light coats works best. Be sure to mask the port and horn
throat scrim so that no paint will get on those items.
