So the polypropylene drivers are now also clay-ceramic filled...
Adding something like clay-ceramic or mica particles to polypropylene cones has been around nearly as long as poly cones. It is a way to make the poly cone stiffer.
Oh yeah, something I was thinking about. When I see you, or someone like Swerd, who has been following DIY designs, with experience building them, and yet still decides to buy pre-built speakers . . . I second guess myself in my thoughts to go DIY . . .
Before I bought SongTowers, I thought I was a confirmed do-it-yourselfer. All I had previously made was smaller cabinets. And I wondered how well building a tall cabinet without a table saw would work. Also I was certain that Salk could do a better job with veneer and finish work than I could.
I wasn't seriously looking to buy new speakers, but after I heard the prototypes, I was hooked. Also remember that early on in 2007, the ST cost $1500 a pair. So the decision to buy instead of build was primarily based on cost and quality of veneer and finish. Besides, even though I know Dennis Murphy, I wouldn't ask him for the ST's crossover schematic.
...Taking someone else's design and building it doesn't really mean you're knowledgeable, just means you can follow directions.
Matt has it right. I follow directions well. I understand other people's designs, talk a lot about them (I'd like to think that I'm not full of hot air), but I don't create my own designs. I long ago decided that buying a table saw and all the audio design software/gear and investing the time to learn how to use all that properly, was more than I wanted to do.
