Just to follow up, my speakers were shipped via FedEx Freight and arrived quickly and without damage. I did have to help unload them from the truck, which meant leaving work for a few minutes. The speakers, crated separatley, weighed in at 330# each and the solo driver had no equipment other than an appliance dolly to unload them with (there was no ramp on the trailer). Had I not been there to help get them out of the semi trailer, I shudder to think how, or if, he might have accomplished it on his own, however. The speakers were shipped on thursday and delivered monday morning from approximately 800 mi.
Thanks again for everyone's input.
