HELP FedEx Mangles Speakers - Refuses Claim

From years of experience in shipping many turntables, amps and speakers, I will agree that there is no substitute for the original packing material, especially form fitting styrofoam isolation. But that is seldom at hand for speakers or vintage gear. UPS is the worst for incurring damage and denying claims (exception noted below), but FedEx is getting almost as bad.

I do ship via UPS, but only via their pack and ship option. Take your item to a UPS store and pay them to pack it. Items packed that way are seldom damaged, and when it does occur they cannot claim that your item was packed incorrectly. It costs a little more, but my buyers and I both agree that it's worth the cost.

USPS. That's right, the good ol' Post Office. All in all, I have fewer satisfaction issues with goods shipped this way than via UPS or FedEx. For small items, the flat rate boxes are great. Use Priority Mail and avoid Parcel Post if possible.

Let me also state that UPS/Fed-Ex will "always" deny the first claim. Just stay with it and try to prove they were
packed to withstand shipping with proper handling.

And THIS would be the reason why I dont buy anything that has to be shipped. No matter what precautions with shipping are taken, its basically a crap shoot as to whether or not what you bought arrives in one piece. I would much rather wait til what I want that can be picked up by driving myself to get it becomes available. All it took was seeing the UPS guy arrive in my driveway and THROW the box containing a Blue Circle amp onto my lawn!Just dont need the hassle that ensued.

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.
