Shipping 80lb amps.

Don’t ship anything in a box or case with a handle on it. With a handle, it’s like a personal challenge to the handlers to see how far they can throw it. I have seen dramatically less damage to items when any handle is eliminated. This even includes a Pelican case in which the handle was sawed off for such a reason. 

Ship on a pallet! I shipped an 85 lb amp via FedEx. It arrived at the buyer with a circuit board detached along with a capacitor. The box was intact with no damage. I guaranteed it was dropped to sustain that much damage.

FWIW I have made it a policy to bring my sold items to the UPS Store or Fedex/Kinkos and pay them to pack.  They use lots of bubble wrap and very stout boxes and I've never had any problems...but my shipments were not 80lbs. 

Have you considered Class D amplification?  Lighter for sure.  /JK

Be careful to insure each box for the full value of the pair if you ship them that way, unless Klaus would be willing to make you a single matched amp to replace one that is trashed.

That will get it there safe.  just realize you are paying about 300% of what it would cost you to package it carefully yourself and print out a shipping label online.

You can tell which sellers use your method of shipping by looking at what they charge for shipping.

Not criticizing since getting it there safe is the most important thing.  I just look at the total cost and decide if I'm ok with that.
