Always turn the volume down immediately as soon as you hear distortion! If you like
listening to loud music make sure that your amplifier can deliver at least as much power
as the speakers’ power-handling rating.
THE SOUND YOU CAN’T HEAR...
Amplifiers, tuners and CD players can all produce inaudible high-frequency signals – and
this doesn’t only apply to cheap products. If your tweeters fail at low or medium volumes
you should have a qualified technician check your system components for dangerous
inaudible signals.
