Cheapest way to ship large speakers?


I have some towers that I want to ship (about 6 ft. x 2 ft.x 2 ft. boxes). Anyone have a good source? UPS and FedEx want $1000!!!

I shipped soundlab m2's from Seattle to southern NJ
on united van lines;no problems encountered at all.
I used a company called R&L to ship my Dyn C4s 2000 miles with no issues.Used they a couple of times and they are great! Quite affordable as well.As far as UPS/ FED EX goes I would avoid them at all cost.I bought a sub about a year ago and it was shipped through Fed Ex.I happened to be looking out my window waiting for delivery when I saw the driver pull up,open his side door and push the box out onto the sidewalk with his foot.
