   It is. When an amplifier is driven into clipping the high-order harmonics   
   increase significantly and can damage the tweeter. This is no myth, it has   
   happened many times.   
      
   Bullet-proof speaker protection is difficult because a high amplitude short   
   duration overload can damage the speaker mechanically, whilst a sustained   
   high-level signal, well within the speaker's mechanical limits, can cause   
   thermal overload.   
      
   The answer is to always keep the volume setting below that at which audible   
   distortion is present!
