I've been told the secret weapon today on inductors or any crossover part, capacitors and resistors, especially the caps, are the Duelunds from somewhere in Europe. Denmark, The Netherlands, Belgium, somewhere in there I think.
They're actually ferrite toroidal cores I believe, but it's good because they are smaller, they have less length of wire, they don't saturate easily, and they add a great amount of transparent vibrancy to the sound. So they say.
I can vouch for the capacitors - the ultimate crossover cap if you can afford them, better than anything synthetic like even the best teflons. The other passive parts aren't cheap either. A life's work in speaker crossover parts from Mr. Duelund.
