Welcome to AudioCircle ada!
Those are some nice speakers. They are well known so you should attract buyers from all corners. Just specify in your listing that they are for sale to local buyer only, no shipping.
Another option is to use a pack and ship company. I use Navis Pack and Ship, but there are others. They come to your house, pick up the speakers, pack them in new boxes, build new crates, whatever is necessary to protect them on the truck, palletize it, insure it and ship it to the buyer on a liftgate. It costs more than a bargain freight broker but there is no hassle. ~$1000 would probably cover this type of complete service to any US address.
