Operation
Listening at Higher Volumes
It requires more power to achieve a reason-
able volume of sound in a large room than
it does in a small room. It is possible (even if
you are not a teenager) 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, 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.
