If you have the original box, that is how the manufacturer shipped it new. To be extra cautious double box it and ship FedEx Ground Freight. As mentioned get a FedEx account set up they are free and they will even pick it up for a small fee. Insure it to be safe.
how to ship a large 160lb subwoofer?
i bought a subwoofer and my friend from another state is holding onto it and was wondering what's the best way to ship in terms of price? i'm getting ups and fedex freight quotes of $900 or so which is more than the subwoofer itself. people sell speakers, subs, and AV racks all the time on audiogon and there's gotta be a better way ... please help =T
