Volleyguy,
I believe the no plastic may indeed be a key feature. It would certainly explain why they sound different (superior) to all the others I have tested which ofcourse use plastic. This is of course based on my own findings. Others may well choose differently.
Regarding the inductors I found the difference compared to other air cores I've tried to be at least as big as with the caps. I use the CAST inductors, and have nothing to complain about. I once tried putting a powerful magnet against a foil coil I was using previously to the Duelunds, and could feel the inductor being ever so slightly magnetic. I tried the same with the Duelunds and could not feel a thing. May be they use a purer grade of copper?
I've found the caps to benifit of 14 days of full playing time, would be fascinating to know if you experience the same.
Your comment about the drivers being in phase doesn't relate to the components, but Duelund's Synchronous Cross Over I believe it's termed: http://www.meta-gizmo.net/Tri/speak/STEEN.html from Harvey Rosenberg's homepage.
