If the tweeters can make any sound at all, they may be OK. If they were blown, they wouldn't respond at all.
A simple test to see if the voice coils were blown out of commission is to very briefly attach a 1.5 volt AA battery to wires connected to the speaker terminals. If the cones or domes move when the battery is connected, then they are probably OK. With the + terminal of the battery connected to the + or red speaker terminal, the dome should move forward with a pop. With the polarity reversed, it should pop inward. Be sure to do this briefly, don't keep the battery connected for more than a second or two.
The same can be done with your woofers. If they are really blown, they shouldn't move at all.
If the tweeters are also blown, you know who to call.
