When I bought my JBL L300 from the east coast for delivery to California a freight company was used. No problem. Sender used Forward Air. I had to pay extra for them to deliver from LAX to the High Desert. They arrived OK. I would not trust FedEx or UPS.
I bought a Carver amp and another Carver piece on eBay. Shipped in same box. A small amount of crumpled newspaper was used as packing. The amp had a bent mounting flange and the other piece was a write off. Items were packed by a UPS store. UPS denied claim.
