jhoak, thanks for the reply. I haven't measured them as yet, mainly because there is no real issue with them. More curiosity on my end.
I have to say, I am very impressed with the sound of these for this line/size of speaker. I also just upgraded the diaphragms. That helped as well. They are quite something. I've been going out of my way looking for the finest produced CDs in my collection. I'm hearing things that I never really heard before. Love it.
