OPERATION

Listening at Higher Volumes
Outdoors there are no walls to reflect and contain the sound. It requires more
power to achieve a reasonable volume of sound outside than it does when you are
indoors. You also frequently find yourself very far from the loudspeakers. It is
possible to turn the volume so high that the amplifier runs out of power. This creates
"clipping" distortion.
Clipping distortion makes treble sound very harsh and unmusical. When you hear
harsh sounding treble from any good loudspeaker indoors or outdoors, turn the
volume down immediately! Those harsh sounds are masking some much more
powerful ultra-high-frequency sound spikes which will quickly damage any fine
loudspeaker.
Cleaning
You can clean the OS loudspeakers with a dampened soft cloth or paper towel. If
the loudspeaker is mounted high up on a wall or ceiling, use a broom to gently
brush it off. Hosing off the loudspeaker is not recommended, as the tweeter is a
precise mechanism which might be damaged by a high pressure stream of water.
