As to the Fourier issue, as I recall, and I am willing to be corrected on this, Aczel believed that most speakers were riddled with fundamental errors that a "C+ student in engineering" would never make. He was of the opinion that a speaker designed without these flaws would sound better than anything out there and he became involved with Fourier to help design such a speaker.
Again, to the best of my recollection, I knew that Aczel was involved with Fourier when he reviewed that speaker and that he was just saying "I told you so". But many others seem to remember it differently.
