Packing & Shipping Large/Heavy Speakers

This all gets back to doing whatever you can to prevent shipping damage in the first place, because once it gets damaged you have lost, insurance or not.

There is a reason Vladimir Lamm packaged all of his electronics in wooden crates and would only ship by FedEx air.

This is why I'd never buy very large, expensive, floor-standing loudspeakers that are not manufactured within a comfortable driving distance from home. 70 lbs per speaker is about my size limit.  A ~half-day drive away is about my distance limit. 

Other large products (like appliances) have in-home service networks. Back in the 50s or 60s, a TV repair guy would come to the house.  Never heard of that for HiFi. Good thing speakers usually last a long time.  

My speakers weigh 133 pounds and came in two cardboard boxes, strapped to a pallet. There was a cover and foam around them and then into the boxes.

All the best.

Thanks to everyone for the advice. I will be contacting manufacturer for advice as well as various crating/freighting companies to get an idea of price and services, and if that fails I will try to (over)pack on my own.
