   If Lowther (or any other similar manufacturer) thought such curves could sell   
   drivers, they would be available in intricate detail, and in every possible   
   configuration. As it stands, there are a goodly amount of published curves out   
   there on these    
   drivers - conveniently truncated from 900 Hz to 10,000 Hz. There is nothing   
   wrong with a speaker that is so-limited *AS LONG AS* the builder understands   
   what he/she will be getting fully and completely. Were I to be restricted to   
   listening only to    
   Gregorian Chant, and were permitted only a 3-watt amplifier, I suspect I would   
   be first in line for such systems. However. I am blessed not to be so-limited.    
      
   I was simply hoping that Andre, after his ringing endorsement of these   
   speakers had the wherewithal to back his claims. But, no such luck.
