   Heh; this reminds me of my own thinking as a kid fooling around with   
   building speakers[1] and thinking of how to make the "ultimate woofer".   
      
   So as absurd as this proposal seems to have been, it raises some   
   interesting questions (non-absurd, I trust). In particular, if one were   
   to try to design such an "ultimate woofer", what would be the main   
   limiting factors to powerful low-frequency response?   
      
   1. Cone size (area)   
   2. Cone compliance (maximum excursion)   
   3. Motor strength (voice coil size, power capacity, magnet size)   
   4. Cabinet size & shape   
   5. Other   
      
   (Hopefully Dick Pierce might be interested enough to answer this.)   
      
      
   [1] My first was an acoustic-suspension bookshelf system, built to plans   
   in Popular Electronics. I remember getting the 6" woofers, really cheap,   
   from McGee Radio in Kansas City. They're long gone, of course; anyone   
   else remember this company? They had an amazing selection of raw   
   speakers and all kinds of other electronic stuff.
