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
