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 loudspeaker. 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 loudspeaker 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.
