> There is no 'patent holder' per se on cross overs
Please forward your remarks to Richard Modafferi _and_ Roy Kimber, and let me know what you find. OTOH, I don't know if Kaminsky is still alive, or if that site is a licensee of his, or what. (Here's a small hint: "Our Infinite Slope (US Patent #4771466) reduces wave interference down....") God, I mean it's so obvious.
In a similar vein, your opinion that you would expect a first order crossover speaker to sound forward is without foundation. It's fine if you like Thiels, or if you like that attribute, but there are other first order designs which are anything but bright, including Vandersteens and presumably out of your awareness Symdex.
When Thiel was first getting dealers, including Herb Hamburger in PA, he maintained that other speakers rolled off the high end improperly. It was a design decision, which in my opinion he has somewhat moderated since the early days.
And most speakers do not measure flat to 20khz, although in recent years more and more might than was the case in the past.
