Difference Between A Blown Tweeter & Crossover ???

I may have a problem with a pair of AR2ax's. How can I tell the difference between a tweeter or crossover being blown?
run the speaker wire direct to the tweeter an play at a low volume to see if the tweeter works.
Look for something obvious such as a bulging capacitor or burnt resistor. Then I would try Bigkidz suggestion.
Remove the tweeter and install it in the other speaker.
