Wood horn builder

Don't know if this fellow is known to members here, I just learned about his website and YouTube channel today.

Here's a video with measurements of one of his horns using a 2446h driver. At about the 8:30 point, after suggesting this driver be used for midrange duty due to break up at high frequency, he introduces a diaphragm he and a friend made of carbon fiber as an experiment. I thought some may find it interesting.
