Best shipping companies

What winoguy said. You don't want to deal with shipping damage, it is a hassle.

Agree with winoguy. You can also save a lot of money if the seller drops off the speakers at the freight terminal at a major airport and the buyer picks them up at the freight terminal on the other end. Most of the cost is the local delivery between terminal and local address. 

@referee1 I have shipped a few sets of speakers across the country and have never had an issue.  I take the time to pack them like this.  Materials cost about $100 and worth very penny.  Requires a skillsaw and a drill.  

@mastering92 I just can’t imagine being able to call any shipping company to tell them to be sure to handle a package with care. What company can you do this with? It can’t be DHL, FedEx, UPS or USPS, as they’re handling millions of packages daily. I use a small regional shipper and have occasionally dealt with their customer service. I can guarantee that they have no ability to contact their workers about a specific package somewhere in the process shipping. I suppose that someone could call them and ask, but I’d have zero confidence that the message would be passed on to the multiple people involved. Would a company that sells and ships audio equipment every day be on the phone asking shippers to handle their items with care?

My advice is to “bulletproof” pack items for shipment and be prepared for damage when it occurs. Items I have received in good shape were first manufacturer packed, then packaged AGAIN in a second container.  Note that this usually means that the item becomes triple boxed.  Better than dealing with damage!

I like and use Echo Logistics. Legacy uses them; where I got this recommendation.
