Yes, that's the same Dr. Moore that wrote the Impedance article in the ITG Journal a year or two ago.
I'd be interested in seeing the differences in bell-nodes for different horns, like a Bach-37 vs. a Stomvi Mambo, etc., etc.
Also, it'd be interesting to see the difference in nodes between a horn straight from the factory vs. one tweaked by a Laskey/Malone/Reeves/Tanabe. Dare I mention, cryogenics?
