Speakers are class 100, you can insure them for what ever you want, within reason, and you pay a premium for that insurance. Make they are securely packaged on a pallet that fit the boxes, and put a piece of sheet good on top, OSB for an example. Strap the whole thing securely to the pallet and shrink warp after that.
We use Saturn Freight they most likely have a branch in you locale look them up at Satutn Freight Systems Contact your local branch and they will quote you. Residential delivery, Lift gate, (required for shipments over 150 lbs) are extra too, from memory $ 50 for each, so guesstimate for your shipment in the neighbor hood of $ 350 - $400
Best of luck
