Niles Audio BG525 - Manual (Page 19)

Operation
Listening at Higher Volumes
It requires more power to achieve a rea-
sonable volume of sound in a large room
than it does in a small room. It is possi-
ble (even if you are not a teenager) to
turn the volume so high that the amplifi-
er
runs out of power. This creates “clip-
ping” distortion.
Clipping distortion makes treble sound
very harsh and unmusical. When you hear
harsh sounding treble from any good
speaker, turn the volume down immedi-
ately! Those harsh sounds are masking
some much more powerful ultra-high-fre-
quency sound spikes which will quickly
damage any fine loudspeaker. You are
much less likely to damage a speaker with
a large amplifier because it will be very
loud indeed before it produces any clip-
ping distortion.
Cleaning
You can clean the speaker with a damp-
ened 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.
