   ** Shame how loudspeakers do not have simple impedances over the audio band,   
   let alone beyond it.   
      
   While it is possible to add passive networks in parallel with a speaker ( ie   
   zobels) to fix this, nobody ever wants to.   
      
   Exceptions:   
      
   Some Magneplaner models and the KEF 104AB were close to resistive over the   
   audio band.
