    For those wanting to try and copy this design ( a couple of forum members have attempts to do it based on the photographs) just open these drawings in Adobe Illustrator, you will get vector art that can easily be converted back into usable CAD files... just a hint for those so inclined.

    Right click and save, of course.

    CAD drawings

    I determined the equations some months ago and wrote a C++ programme to verify the results.
    I recently turned the equations into CAD drawings, and a CNC cutter will, with a little luck,
    soon turn the drawings into a tangible result.

    The adapter

    Here is a glimpse of the adapter. The transition from circular to rectangular, while maintaining a linear expansion of the cross-sectional area, was mathematically the most difficult part of the reverse engineering.

    What people will do to save $ 60,000 bucks. You gotta beat inflation some how.

    Are you sure that you really understand what we are doing here?
    Most of us can't save 60,000 as they do not have it.

    But believe me, if I can manage to build these Everests this way it would be WAAAYYYY more fun than buying them in a shop.

    Except my 250ti (modified) I have not owned one stock pair of JBL's. And I have owned a lot.

    There's about $14K worth of drive units in those anyway - and speaking personally I think I would spend that amount in other ways

    That $ 60,000 can get me two cars with BOSE audio installed and some pocket change for gas.... I,ll keep my Paragon at home hooked up to some vintage amps. But I,ll watch you put together a Everest II clone. By then JBL will put out a Everest III. bookshelf line.
