If anyone is interested, here's the website for the speakers' manufacturer:

If you click "English," mouse over to the "Products" menu and click down to the "High Power Horn Speakers," you'll find our E-Class (and ATI) friend as the TU-300 model.
It looks like they at least come with the drivers per Kingstar's spec sheet. If ASC is dropping their own drivers in, I must give them all the credit and laudations possible. While you can't stop these horn assemblies from looking atrocious, to give them some chance of longevity is noble indeed.
I just hope its true.
