Heco Statement Mode D'emploi/Certificat De Garantie page 11

If the output of your amplifier is significantly higher than the rated power handling capacity
of your speakers extremely high volumes can physically destroy your speakers. This
doesn't actually happen often but you should be aware that it is possible.
Weak amplifiers with low output ratings can actually be more dangerous for your
speakers at medium volumes because weak amplifiers may overload much faster than
powerful ones and this causes measurable and audible distortion, which is extremely
dangerous to your loudspeakers.
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.
