I may have to ship one of my speakers from my state (Alaska) down to Polk in San Diego for repair. Luckily I still have the original box and all the packaging. I have heard horror stories on here about shipping speakers with FedEx, which is who I'll probably have to go through. Does anyone have any suggestions as to how best to protect myself in case the speaker is damaged in transit? Obviously I'll have them insured, but beyond that, is there anything else I can/should do? Thanks!
