Speaker Packing?

you are wise to hesitate shipping speakers,don't start now,YMMV,Bob

If you have to do it, I would suggest getting someone to make crates OR have Fedex Office (aka Kinko's) or UPS Store pack them. They will charge you big $, but then they will on the hook if the packing is not up to snuff, so that when the big brown guy runs a fork lift thru them, they cannot claim that you used a box w too low burst strength!

Also consider strapping them to a pallet and shipping freight.

I don't think Fedex or UPS will offer that service but may be wrong. There may be local packaging service companies that will do this. That said, building packages for speakers isn't rocket science. Depending on the speaker size it will be labor intensive though and take some doing to procure the packaging material. Still, you may be better off trying to sell locally, or regionally (eg deliver them yourself or have the buyer meet you w/i 100 miles). Regardless of packaging, the moving/handling in transit can be hard on speakers as they're not engineered for shock stresses.
