Derek, one way you can check is to, very carefully, push on the driver cone (not the dust cap, not the surround), making sure to put equal pressure around the cone, so it is not pushed out of alignment. Just push it a few millimeters, let it return to it normal position, and push it again. Repeat as needed. Listen closely. If you hear any scraping, it is blown. Also, if you don't push it back in a perfectly straight line, it will tend to scrape. This won't typically cause damage, it just won't indicate it is blown.

BTW, it can be blown, and still not scrape, but if it scrapes, it is blown.
