Hey Bonzo, how's it all going?
Have you decided on some model of speakers mate?
With Re to packing, as someone suggested, the original manufacturer will have the correct packing for their speakers. They will also be much safer shipped in their original packing.
There is no point in getting a good deal on the speakers and doing a shoddy job on the packing and finding the speakers damaged after they reach you. That would be very discouraging.
Get the seller to contact the manufacturer and come to an agreement with the cost, would certainly be my best advice as well.
Cheers, RJ
