A pair of CWs back to back sitting in the middle of a 40x48" pallet aren't going to be damaged by a forklift. If the Forklift operator somehow misses the GIGANTIC holes in the bottom of the pallet and stabs your speakers 6" above where the forks are supposed to go... well, then forward air needs to man up and pay for them with their insurance.
If the vault was easily found and quickly shipped into action I feel it would be worth using. But, when someone needs it, posts asking where it is... no one seems to have a clue. And you know a klipsch enthusiast doesn't want to wait a few extra days for his CWs to arrive.
I say, screw that crate.
Send it back to whoever made it (if they even want it) and be done with it. It's not worth the hassle.
