Look for the model of the woofer, on the back of the driver... you may get lucky and its something common that you could do also search for.
Canton i think is bigger in Europe, contacting them is a good first step. Sometimes these companies will suprise you and ship one out for a reasonable fee....
Other than that, searching US and european sources on the Internet ( ebay, google, etc) is another avenue.
If all else fails ... some adventurous types just try to buy a "close match" to the driver, at a good price. It will not sound perfect, and it may not even sound good.
