What you may want to consider is asking the speaker mfg. who they use. I did this with Magnepan and found that the shipping company they use is used to handling fragile packages such as speakers.I shipped with them and had no problems whatsoever.
How do you ship heavy oversized speakers
I have some heavy (120 lbs each) and oversized (60"x22"x8") speakers that I need shipped to me (I bought them, and I am not doing the packing) The weight is borderline for UPS and FEDEX GROUND but the size will be bigger than allowable (130" for Length + Girth) once packing materials are added. What have you done in the past for these larger speakers? Pick-up is not an option as they are in CA and I am in WI. For some odd reason FED-EX 3 day air might work, they allow 165" total dimensions, but it will be close to $200 per speaker, not including packing. I would prefer the $60-$90 per speaker that UPS and FEDEX Ground would charge if the package was just a hair smaller. PLUS has anyone used any shipping services that do the packing for you? What are the costs and experiences you have had? I need help as soon as possible on this, thanks!!!!!
