Shipping speakers is how members get negative feedback, they have to be well packaged, best to have original packing material and prey they arrive in good condition. Best to do a local sale if possible.
I shipped a tube preamp and the packing was bullet proof. This was on a Fedex truck that rolled over in transit, heavy items crushing the box. When it arrived the packing material was expelled from the box and the preamp (still in the box) had a bent frame. The buyer reported it still worked perfectly. I told the buyer to take pictures. In the end I let him keep the preamp and the claim money.
