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'd also say freightquote.com. I've used them without issues and you can choose the least expensive of the quotes.
With Fedex and UPS, you run into "dimensional weight", which may be 3 cubic feet or some maximum height (40"?) and can easily double the costs. Found that DHL is easier and cheaper on bigger packages. Although, not sure how cooperative it is on the receiving end for home delivery. Couldn't be any worse than Fedex.
