I said there are no patent holders on First Order Crossovers, not 'any crossovers', and I didn't mention the Infinite Slope or Ray's special, relatively new crossover, as I recall--the issue at hand though, isn't that no one can patent them, its just that one infinitessimal change makes enforcing the intent of the patent impossible. Jim Thiel who had not patented anything up through 1999 when I worked for him, said, and I am recanting his words to me, as to the efficacy of patenting what I thought were some great ideas. It simply isn't realistic to patent certain items which are replicated with such frequency and similarity, in which changes of small measure destroy your case in court.(Not to mention the cost of enforcing, and protecting your patent.) I do notice from his web site that he has a patent pending re his SmartSub.(So all things change in time.)
The comments I made about first orders sounding 'bright' were, in this context, probably more regarding THIEL. Vandersteen is not only, not bright, many people find it lacking in what they call fine detail. I say they sound rather neutral and pleasant. One designer I was roaming the CES show with when it was still in Chicago, so an Ice Age ago, said upon hearing the latest Vandersteen, "Typical Richard design, not bad, won't offend anyone, but it lacks enough detail to make it interesting."
I have a wide berth of listening experiences, having visited about 100 stores across the United States while working as Director of Sales for THIEL, owning a retail store for 12 years, and attending every CES for many years; and my experience was that MANY 1st orders sound odd, and as Joseph of Joseph Audio was pointing out after my post, Jim is the most talented or advanced of the known designers employing first orders, and that the issues surrounding that design are, at least to him the same as to me. "Sit in the right place, eliminate room reflections, and play them at a moderate level." (I paraphrased to save time.)
What I hear, (and I don't expect you to hear the same thing by the way) is that the sounds emanating from the drivers well out of the dominant sound (frequency) range, sound odd, and amusical, creating a sound which is foreign, (to me) from the orignal and or intended sound.
Jim Thiel, insofar as I know, still thinks that all speakers should go 'flat' to 20Khz, it's just that most designs don't achieve that goal.But the perceived 'brightness' that people carp about with THIEL's aren't near the 20Khz region anyway, more like the 4 to 8Khz regions.
I hope this clarifies what I meant in my previous comments.
