Best way to ship large / heavy speakers???

Shipping by Bax Global has worked well for me. I've shipped several pair of speakers in the 200 pound range with no problems.

Good luck!

You may want to put some additional styrofoam material inside the box. It can be bought in a 4' x 8', it comes in deifferent thickness. Additionaly you can put shock sensors
and/or tilt sensors to the outside of the boxes, that way the buyer will be able to notify the shipper of rough handling to the boxes. Hope this will help. Hector.

Do a search you'll find lost of info as this has been discussed extensively.
