http://www.freightcenter.com/The website provides a comparison of various freight carriers and you can then choose the least expensive one. I ended up using R&L Carriers. I used them and all went well from the point of shipping to destination. Of course you will have to put the speakers on a pallet. I happened to have the original pallet my speakers arrived on. You can get the straps to securely strap the speakers to the pallet at places like Home Depot or Loews. The trucks picking up and delivering the speakers will both need to have a liftgate. I did the work of securing the speakers to the pallet in my garage. The truck driver pulled his pallet hand truck into the garage to slide it into the pallet, raised the pallet, and rolled the speakers down the driveway to the truck on the street. Do some research on the net and get the correct Class code for speakers which is important information that you will need when doing the online forms for freightcenter.com. Insure the speakers accordingly. Communicate well with the buyer.
