Default Mechanical Linkwitz-Greiner

Vidar Oeieraas has made a page where he talks about modifying a driver to implement a mechanical linkwitz-greiner filter. Has anyone here tried this?

The page.

NB. The page is in Norwegian, but the illustrations should be clear enough.

PS: For those of you who are curious about the lower drawings, he's talking about:
(a) balancing the compliance behaviour of the spider and surround to improve linearity,
(b) using a progressively thinner membrane to get a constant force-arm factor, and
(c) shaping the dustcap and cone according to a horn (presumably tractrix) contour for a particular response and dispersion.
