Shipping large speakers

I have a hot tip for you. Call Steve Title at Gateway Crate and Freight. He can arrange al this for you and the best part is that he can offer very inexpensive insurance. They even have a white glove service. 

Pallets and shrink wrap are indeed ideal.

Tell him Jim at Sounds Real Audio referred you. 

Strapping is much better than shrink wrap. 

Definitely strap the boxes and strap to the pallet. Actually, I shrink wrapped the boxes before strapping.
My buyer used Uship:

It worked out quite well.

I've shipped speakers before with generaly good results.  A pallet, shrink wrap and straps are a must for large speakers.  I am most interested in what would be the safest and least expensive service.  I just purchased a pair of speakers directly from the manufacturer.  They are little over 100lbs each and they have been shipped well packed in two separate boxes (no pallet) via FedEx.  I'm hoping for the best....
