HOW TO AVOID DAMAGE TO YOUR VALUABLE SPEAKERS
All MAGNAT loudspeakers are designed and built for optimum sound reproduction with the tone controls in the central
position – i.e. with "linear" amplifier output. Turning up the bass and treble controls too far delivers more power to the woofers
and/or tweeters, and at high volumes this can actually destroy the speaker units!
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.
