First off, Paul klipsch once said, if I can see farther then those before me, it is because I stand on the shoulders of giants. You mentioned specific designed items that have been introduced as products. Paul and I hardly ever discussed individual significant ideas. We did talk a lot about concepts. Everyone of the specific items you mention has some predecessor. Looking ahead by using conceptual ideas makes one ask a lot of what if’s.
Taking a look at your list (and I know you can more specific items), I can tell you that whether it was available or not, we discussed every single item on your list and others. By taking a look at what was going on around us, seeing where the state of art was heading (remember Paul read a lot) and conceptualizing what that might lead too, put me behind in a lot of product designs I was working at the time!! Lol!! That truly was the fun part for me. I had/have a lot of latitude to “play”. That was the second greatest thing I treasure in working with Paul klipsch. The first is that he was my friend.
Honestly I don’t think I will because of way he taught me to think about acoustics, projects, ideas, etc. it was not specific items. It was concepts. I understand Paul’s philosophy and adopted it as my own. Because it made sense. And because Paul understood that he and I were on the same wavelength, he encouraged me to “conceptualize” and see what direction that would lead us to. So you see, their is some “Delgado” in klipsch. But that is only because I stood on the shoulders of a giant.....Paul Wilbur klipsch.
