There is a pair of new Lansing compression driver components that are used in the new home settings (Model 435AL) on Fleabay now.

Apparently, they have aquaplased aluminum diaphragms!

I suppose you can guess from this that the other Lansing company believes these outperform titanium frams that have been their standard bill of fare on cinema, SR and other applications for about 20 years.

As far as I can tell, Altec and its successor GPA have always made diaphragms from aluminum; right?
