It's hard to tell from the heavy refraction of the acrylic-filled shells, but it looks like the mid-driver is different from before (smaller), to make room for an absolutely massive dual woofer in the middle. I guess they weren't kidding about the 'DW' part! Also, I can't tell what driver that huge dual woofer is... it might be a new component not yet listed by Knowles/Sonion.
Also, there has never been more English on their website; I wonder if they'be done that on purpose? I know it might just be something of a particular design choice for websites in foreign languages, but it could also mean that they're slowly becoming more foreigner-friendly.
