Prefered Freight Company

I was wondering if there was any frieght companies that anyone would want to warn me about or recomend? I have been in the markey for some speakers and I have seen some very high freight rates. I dont mind paying, but I figured I would ask...
I have had great luck and great prices with Pilot Air Freight. For example I shipped a pallet of about 400 pound from West to East coast for 300 bucks. I also had great service with BAX global. They send a set of Maggie 3.6s from California to Italy for 200 bucks. They won't pick up from me anymore as they say they only pick up from businesses? I would say number one rule is speakers need to go on a pallet so they can be arranged the way the should be and can't be moved. Giving a mover a speaker in a box is a recipe for disaster as they can topple the box end over end if needed to move it around. I will never ship a large speaker again not on a pallet.
Bax will not insure speakers for more than 500.00 under any circumstances. YRC has been great and their rates are very competitive.
Regardless of which service you use, I would suggest using a device that indicates damage and/or shock. Google freight damage & shock indicators to see what's available.

Using Greyhound bus like Dill suggested is a good choice but if you have to truck, palletize & make sure the trucking co. uses air ride trailers.

Also, some trucking co. use lift gates, so there's no dropping the speaker off the back of the truck.

Additional options are freight expediters (like All-Types Expediting) that use straight trucks that are set up for faster service. Some of these trucks are small like basic cargo vans Moving co. are another way to go, although a lot depends on the driver & crew and how they blanket wrap & strap loads.
Old Dominion, you can get Location to location for a very good rate, or dorstep delivery for an extra charge. I've shipped Magnepans a few times and never had any issues.
