Thanks for responses thus far.
The packing consists of:
Inner box, speakers plastic wrapped and bubble wrapped with hard cardboard attached to the top, bottom and driver side, the inner box filled with foam to the brim and taped up.
That box is then double bubble wrapped on the outside then, the box is inserted into the 2nd box with 4 inch commercial foam slabs top and bottom - cut to snug up inside the 2nd box, sides are filled with foam peanuts for another barrier on the sides.
From all experience and knowledge here is sounds as if I am up against a challenge regardless, based on the fine-print and claim denial policies. I too have been burned by UPS but never by FedEx ground until now.
I am in CA if that has anything to do with the legal recourse. Keep the information flowing, please and thank you everyone.
