Long throw 5 1/4 woofer??

I like very much my Totems Staff with a 5 1/4 woofer. The bass is very nice and deep (for a small woofer), however I wonder what do Totem Acoustic means by "long throw woofer". In their web site they do not list the x-max for this particular woofer. Any ideas about the x-max of this woofer?? Searching the web I found that the woofer is made in Poland (GDN 13/40/2) and in you tube there is a video where the woofer is feed some power so that its excursion is of about 3/8" one way!!! Can this little woofer handle safely an excursion of this magnitude?
