my point with the dynaco example is that dynaco successfully mated a 10" woofer with a tweeter and produced a speaker that usually sells today for more than it did originally. and they did this in the 1970's.

I believe when all was said and done, they sold 1 million of those.

Early version of a 10" woofer plus tweeter? Sounds like an Advent to me. I think they sold a few of them IIRC.

Dynaco Speaker Component Info

Ed Laurent notes that over 1,000,000 A-25s were eventually sold; Dynaco would import the finished speakers in containers of 1100 units and drop-ship them to dealers or large customers. Approximately one container per week passed through the shipping department for several years!

I don't see any diffraction control, but maybe they didn't know about that back then.
