I do have an impedance chart, unfortunately, for some reason I never got around to uploading it. It's nice and smooth though, like my other models, very tube friendly. When I get back to Tulsa, I'll upload the chart from my measurement system.
By the way, one of the links contained in my last post is called "Crossover Optimization for DI-matched two-way loudspeakers." That thread is a general purpose explanation of design principles, but it uses the three π loudspeaker as the example. There's a video showing some measurements I made in the first post of that thread too.
