No success with tracking down a pair 2441 diaphragms so I am now considering other options while I wait for a pair.

Besides the obvious Beryllium diaphragms are there any other genuine JBL diaphragms that would do the system justice? Do any of the newer aquaplas'd diaphragms fit in 2440 cores?

Looks like my only real option may be the Radian 1245 but I don't want to soften things up and I think the 2445 may do the opposite and make it too harsh.
