Finding reasonable Shipping for heavy, crated speakers to ship cross-country

Would any of you fellow Audiogoners give me advice in finding reasonable shipping rates for two crated speakers, 140 lbs each. UPS quoted $375 and FedEx online showed $310. I originally received them a dozen years ago for shipping cost of about $175 on a truck with a moving shipper with a bunch of other folks items of course.
try typing "heavy shipping" in the search box. There are many threads on this.
FedEx ground gives HUGE discount on ones who open an account with them so instead of $310 you will get away with near half quoted online.

Another way is to accept bids from insured professional companies via which is I guess somewhat similar to piggybee
Thanks to all of you. Gosh I love Audiogoners, you guys are great!  Czarivey I'm going to head to FedEx and open an account and see what happens. Thanks. Erik
