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.
MAINTENANCE
The lacquered surface is best cleaned with a mild household cleaner. On no account use furniture
polish or similar products on these surfaces. Please also do not use a microfiber cloth as this may
damage the surface.
