And in the Warfdale thread :

I have been doing the same, and have recently been listening to a pair of 10" French-made Ferrivox drivers (Ferrivox used to make drivers for use in cinemas etc) which I like very much. This driver has a paper cone and surprisingly soft paper suspension.




Above is an image of one I found on the internet ; this particular example looks a bit rough.

I have stopped worrying about the sort of duty for which a driver may have originally been conceived... There are no T/S parameters for the drivers I've been trying; I just buy them, plug them into the horn, listen, and figure that if they are not suitable for this application (upper bass horn) then it will be audible in the form of poor performance. This driver for example does not have a particularly stiff suspension, so in theory it is not ideal for horn loading... Nevertheless, I like what I hear.

Did you ever try the Goodmans Axiette 8" in your upper bass horn? I have not... Not yet anyway.
