Shipping Heavy Speakers: Freight of FedEx

I worked shipping /receiving for a while recently. Pbnaudio ,good advice! Also may want to make sure speaker boxes are centered on the pallet ( nothing hanging over or to close to edges of pallet) to keep from having another pallet or machinery ,boxes,,,, from hitting your speakers while whoever is loading unloading the truck or moving pallet in ware house. Make sure if possible to cover the speaker boxes with additional protection ,,cardboard ,corner protectors ,,,as well as possible.Make sure they put plenty of ,Do Not Double Stack , and,Fragile stickers on all sides and on top of pallet. Make sure the boxes are held down very good ,as to not slide off ,over the edge of the pallet. Assume the pallet will be moved many times with fork lift as well as manual jacks.Of douse use a good sturdy pallet,,no damaged or flimsy pallets .

Lol,meant to write ;of course,,not -of douse
