I've gotten to the point where wooden crates are my preferred method for heavy stuff. I got a pair of tubed monoblocks (the Stippich amps), 140lb. each net...these were each boxed inside a crate (and bolted to it) made from 1/2 plywood and strapping. That crate was in another larger crate, same construction, surrounded by styrofoam peanuts. The outer crate(s) were bolted to a pallet and then shrinkwrapped to boot. Total weight was about 350lbs. for the amps, 4 crates, and pallet. Over $600 to ship via FedEx air freight. But worth it, since they arrived in mint condition. Took me about 4 hours to unpack and get in the house by myself.
