Seas dubbed it the "H393". it was not made after 2004 I think. (hence you question here I guess.)

E-mail: info@hifikit.se Drop them an e-mail and see if it's still available. (If the they don't have it these dudes could tell you what to substitute it with, hopefully)
Solen (canada) and Madison (Us) could have it too.
This is a old design. Pre -98 at least.
You could try Clofis (Netherlands), as well e-mail : verkoop@clofis.nl (I'm sure they understand the Kings finest even though they are dutch..)
Happy hunting!
One of the assemblers at seas, that is, this person then, told me that one can order, at a premium, any driver assembled to spec
if one absolutely have to have a special type. Normally they won't entertain this type of prototyping, but if one got together and ordered enough, I'm sure they could build a limited series of just about any conceivable driver they have ever had, or you could dream up really.
I believe one can order "one off" sets as well, but this isn't gonna be cheap at all.
How about just asking SEAS if they have something similar in today's stock? or
Simply ask SEAS a question directly!Last resort? Flex units...
