DYNAUDIO Contour 4 X-over

Hi All,
Is there anybody who have a schematic of the Dynaudio Contour 4
three way speaker.
I got a handdrawn schematic from a friend. He built the speakers as a kit,back then
when you could still get Dynaudio kits round the corner.
However, this guy have fiddled so much with the X-over thru the years
that I'm not sure the values I have are meant to be.
I'm building a pair and there seems to be a dip somewhere in the
lower region of the dome midrange. Otherwise quite impressive.
