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 elec-
trical failure by overstressing the speakerʼs 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.
