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.
