Having shipped more than a few, I would say that speaker crates should be in the upright position (as a speaker would normally be in your home) and STRAPPED to the pallet first then shrink-wrapped. This is the way most palletized loads have reached me over the years and it would appear best practice particularly when I remember that in the shipping distribution centers, these pallets are being moved via lift trucks that sometimes take corners too fast and the load have to deal with alot of
'sway' going around corners.
If your speakers can fit 2 on pallet, same advice but put a couple of additional straps around the crates to strap them together, then strap down to the pallet followed by the industrial roll of shrink wrap treatment.
