Thanks for the clarification! Have extensively studied your work as well as that of Linkwitz and Don Keele. I have a pair of Don's CBTs and so have experienced what they can do. As you have indicated in your writings, there is a broader sets of problems to be solved if we are to improve sound reproduction. I do not know whether the speaker answer is different drivers, more drivers, more processing or different configurations, but am pretty clear it is beyond what the mainstream offers today.
It is encouraging to know that you are more open minded about dipoles than some may have thought. Your position on CBT speakers is not well known. It seems to have been summarized as they might be good surround speakers. As JBL has commercialized them, am guessing you may have more than a passing experience with the technology. Please let us know if you have more insights that you might share?
