I once got speakers from UPS that had been packed just as poorly. They were left on my steps with the to 1/4 of the box nearly gone. You could see the naked speakers and peanuts were poring out of the huge hole in the box.

It was a shockingly back packing job from a guy with superb feedback, and a horrible job by UPS. Yet, for all of that the speakers didn't have a scratch on them!

Damned odd deal.
Anyway, good luck with your claim.
