Old Dominion Freight http://www.odfl.com/ is the company Magnepan uses and recommends, and they may have special rates for their speakers since they're large but relatively flat. They're generally shipped palleted but they could likely advise accordingly.

Has anyone shipped Magnepan 3.7i , if so what shipping company did you use?
