lol, i told you guys, they throw and drop ish. I mentioned it far before i saw any of the threads about damaged subs. They are pricks.
USPS is legit IMO. Never had a problem. I do single boxed flat rate for motors that are around 50 lbs and they go fine!
If anyone is worried about paying more for usps on non-flat rate boxes, goto a 3rd party shipper and send it media mail!(this service is only for books and similar things and does not cover audio equipment and they can open and inspect the package and send it back to you but it works!) I shipped a 30lb IDMAX, the box was like 12x12x9, for just under $20 aways across the country.
