Madisound has a retrofit program. With Vandys, Thiels and Maggies, I'd buy American in the 1st place.
Driver replacement China
Lots of speaker companies are designing their drivers and then having them made in China. What happens when the speaker company goes out of business? How could you possibly get a replacement driver when you probably would not even know which Chinese factory they came from? Seems like a reasonable question due to the frequency of company failures in this industry.
