Shipping floor standing speakers

If your worried Double Box them. FEDEX/UPS STORE can make boxes for you if you cant do it on your own. Just pass the added expense to the buyer.

What is the weight?  If you go much above 70lbs per box, that is when the horrible handling of FedEx UPS creates a risk.

I shipped a pair of Zu Essences which are packed in like 4 inches of foam.  I assume FedEx dropped one of the boxes off the back of the truck and the base of the speaker was damaged.  
Palletizing and shipping via freight is better but far more expensive.  If you ship those LTL, expect it to be $500+ for freight.  
Best thing is to sell them locally.  

Have never had a problem with FEDEX shipping speakers weighing up to 150 pounds each (Tektons/Salk etc). I have a FEDEX business account and usually ship gear out almost every single week. NEVER had to file 1 claim in all these many years. YMMV

Thank you so much

second layer of cardboard around the boxes. literally make a second box.

seal the second box via a high powered glue gun (for the flow rate).

this stabilizes/stiffens the whole thing into being nearly impregnable to ripping open due to any stressing and also helps enormously in preventing puncture.

I’ve even shipped dynaco A-50’s this way and also shipped many others.
