There is much more technical material available to read on the Rythmik Audio site, some of it way over my head. Not all of us have PH.D's in electrical engineering, Brian! ;-)

  You don't need to be a PhD to build a proper servo-controlled woofer setup. I (and others) have tried to query Brian Ding regarding the specifics of the Rythmik implementations, but he was either unwilling (or unable) to elaborate regarding it. In fact, discussions regarding Rythmik got to the point of being disallowed on a couple of forums.
  
  I was left with the impression they are just simple servo-controlled setups. Those have been essentially perfected long before Brian Ding was working on them.
  
  Subwoofers are one of the easiest audio projects to do properly. There's much marketing done in the audio industry, and especially so in the subwoofer category. Watch your wallet. :)

    We're all free to have any impression we care to. I believe the U.S. Patent Office has stricter rules ;-). One difference between the Rythmik and other servo-feedback designs is right in the name of Mr. Ding's creation: Direct. I'm left with the impression that the direct nature of the design is a noteworthy difference, but not nearly all there is to it.

      The U.S. Patent office is a joke when it comes to this type of thing. It ceased to be about any type of technical innovation a long time ago.
      Ask Brian to explain the "Direct" implementation to you. :)
      
      Sub-woofers are easy.....that's why so many people build them. Same thing with cables.
      
      Keep your hand on your wallet and beware of the marketing.
      
      Cheers,
      
      Dave.

        The "direct" aspect is the one thing I DO understand! It's only the tip of the Rythmik iceberg though.

        The "Rythmik iceberg." Classic!!
        I guess we've found the reason why these drivers are no longer available.
