AmandaRae, the first photo looks like one of King's designs. Bob Brines used much of King's theory in order to build his speakers.
The second post, the ones with the supertweeter, those are the Ft2000A. The scarcity of the F200As make them limited and sooner or later, precious in the used market. Although I think just a discening few who lucked out buying those drivers will be able to enjoy them. Foreing sites, like DB Design, from the Netherlands sold their last pair, used for a high price. Maybe they will be available only from some Japanese DIY stores.
