Those specs describe a compatible alignment. You could almost say equivalent but since the numbers are different, I like to say they're compatible instead.
Eminence has done this a lot over the years. They're fast and loose with their spec sheets. But don't take this as a slight on Eminence, in fact, maybe it's more honest to republish specs every year or two. After all, materials change slightly over the years, suppliers change, different vendors are subcontracted, etc. In fact, you can even take the same driver, test with a 0.1v signal and get one set of numbers, retest immediately with 1.0v and get a different set of numbers. Run the speaker at high power for a few minutes and retest and it wil be entirely different.
The important thing is that the electro-mechanical specs, when used in a system, provide the desired response curve. They do in every case I've found of Eminence drivers that have shifted from one season to the next. They're different but not in a meaningful way. That's why I don't get too excited about changing spec sheets posted, if you sample a few yourself, you'll likely find matching numbers, or very nearly. They're compatible parts.
