Oh, yeah. I remember that thread now. When Darrel mentioned this day before yesterday, I was thinking we were talking about something like Magnepan's, not a dipole made from a cone driven speaker. I was wondering how he was getting efficiency in the 90's. Now I'm with you.

Hey Wayne,
Sorry for the confusion and a big thankyou to Dave for getting us on the same page.
I realy wanted to also thank you Wayne for that Wave propogation graphic! Is this Graphic something that you created or did you find it elsewhere? Got any more like it. It sometimes helps me to understand some of this ,if I can see a visual portrayal of it!
Thanks guys!
Darrel

That animation is on Daniel Russell's website:

He also has a good document about transmissions lines:

Here's an excellent write-up on how to measure polar response of loudspeakers:

And several other good lab excercises:
