HELP! Large speakers fell over during shipping.

Bought a pair of Dali Euphonia MS5 speakers. They must have fallen over during shipping. They were upside down on the pallet when they got to my house. 155Lbs for each box.
My question is, what could have happened internally? Could drivers be harmed? Crossovers? I refused delivery, but now the seller wants them re-delivered so the insurance agent can look them over. I never took them out of the (destroyed) boxes, but now I’ll have a chance to, and check them out. What should I look for (even if they still sound good)?
