dont even think of just getting any old woofer from a store to replace your blown woofers,you will most likely not be happy with the results.
you should be able to get both of your woofers rebuilt pretty cheap,you should be able to find a rebuilder in your area,just call around to some local guitar shops in your area & chances are they can refer you to a rebuilder.
if you are near detroit i can recomend a very good rebuilder.
