From what I understand, Eminence is kind of fickle about the way they talk about product changes. Sometimes they don't admit to changing, other times they talk about how changes have evolved and improved their speakers. What I'm told is that Eminence keeps specs of the updated models compatible with the older ones. In that sense, the speakers are the same. They have made improvements though, mostly in the voice coil for power handling, I think. There may be other side effects. See the link or write on the Pi forum for more details.

Thanks for the mention. The specific page that shows what speakers were changed for 2004 is shown below. It is a list of drivers having parameter updates to be used in Eminence's version of BassBox, the Eminence Designer.
