I've just shipped a grandfather clock and a pair of POLK SDA(155#ea) speakers via a company called Freighters and Craters. They will pick up, create custom packaging if necessary, deliver, and setup if required. I have been very impressed with their quality and knowledge of physics.(ie, how to pack). Their pricing is very fair for the quality and care they provide. If inexpensive is the only concern, then you can probably find a lower cost carrier, but your speakers may be converted to the inexpensive type by the time they arrive. Heres a link to their on-line cost estimator: http://CratersAndFreighters.com/equote Good luck Carl_S
