Eminence does this every couple of years. They change materials or manufacturing processes and the electro-mechanical parameters shift slightly. I've often wished they would chage part numbers or at least provide a version number to indicate changes but they won't even consider this. But they're pretty good about keeping the specs in a compatible range so the driver acts the same. Fortunately, I've not seen them change the diaphragm during these incremental changes, because different cone flex and breakup modes might make the tonal character of the speaker more different than slight T/S changes.
