Niles Audio OS6 - Manual (Page 19)

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 speaker. 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 speaker 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 OS6's with a dampened soft cloth or paper towel. If the
speaker is mounted high up on a wall or ceiling, use a broom to gently brush it
off. Hosing off the speaker is not recommended, as the tweeter is a precise
mechanism which might be damaged by a high pressure stream of water.
