Op,
I clearly have no idea as I never have seen/heard about the 2440 with phenolic diaphragm. Who know perhaps they did it. The phenolic diaphragms were the invention in late 60-70s and a remedy against the nastiness of the first SS amplification. They are OK but to my taste they have no necessary for me transient characteristics. Interesting is that the new Radian production of the aluminum diaphragms is much more interesting then the original JBL production – so you are in a good path. I would be VERY interesting to hear your feedback about your new MF driver.
