These definitely aren't too large to ship as they aren't that much different in size than many floorstanding speakers that ship routinely strapped to a pallet. The problem is they aren't worth the cost of shipping. I don't think a local dealer will give you anything for them but if you list them locally on CL or similar for a very low price you will have a decent chance of getting someone to take them off your hands.
