I was very interested in audio around the time you were designing speakers, but I had to contend with the electronics, and left the speakers to the experts. Speakers were a mystery to me - although I do recall "disassembling" a few loudspeakers as a child. I look forward to reading your references.
I assembled my first stereo system around a pair of Acoustic Research bass-reflex boxes. The radio studios where I worked had Advents everywhere, plus a pair of ported JBLs with a comfortably forward sound in one of the studios, and large (3' by 3' by 3') Altecs for really loud sound at remote locations.
Not that it matters, but Kentucky was my home for a while when growing up. (Nothing to do with speakers.) My dad's company sent him there to help open a factory. I think Kentucky was chosen because land and labor were available.
