I also recommend a wood pallet for expensive speakers even if they are in the original boxes. My Aerial LR5's came from the West coast to NYC in great shape as they were wrapped on a wood pallet.
More shipping damage again?
Last two items I have shipped FedEx have been dammaged. The first one was a pair of montors in original box. This time I shipped a beautiful subwoofer but first re-enforced the foam inside box, then put it in a larger box which I also foamed with several layers.. The sub still shows up with bashed in corners. Geeeez , I am sick.
