Prof, as a technical note, that wavy driver behaves better than any of the previous cone drivers as well as supports the tweeter wave-form launch very nicely. Therefore the direct series crossover path is simpler than any previous Thiel driver. Jim had always corrected for slope anomalies in all the drivers, which puts additional components in the signal path. In the x.7 models, fewer components are required because the fundamental driver performance is so good. Part of what you hear is the thrill of nothingness.
I am glad to hear your enthusiasm.
My present work on prior models is to refine the required passive components to minimize their contribution to the signal. Most of the parts are on-hand for my PowerPoint experiments which will also inform beetlemania's CS2.4SE upgrade. We can't brag about vaporware, but I am pretty excited about the potential improvements.
