In your listening experience what really strikes you and says "Hey, I'm the 70-20, not my little bro!"?
This is purely from memory, but the 70-20 version was smoother and more transparent sounding to my ear. Not by a large margin though. I will have to make a pair of these, and now with having our own Klippel NFS, design a fully optimized crossover based on the resolution the NFS is capable of.
