   Exactly. If you plot the impedance curve of an 8-ohm speaker, the impedance   
   will generally, but not always, drop below 5 ohms at resonance. This has   
   been true for over 40 years.   
      
   When I said impedance, I meant impedance, not DC resistance.   
      
   This is getting to be just tiresome nit-picking. You aren't even making a   
   distinction here, because I essentially said the SAME thing.
