Good news of your interest. I do not have the original boxes. I picked up the system locally in a U-haul van, wrapping everything in blankets for the move. I know that the UPS store close to me has all sizes of heavy duty boxes. If each item was individually packaged with 4 inches of bubble-wrap between the item and the side of the box, it will travel well. That is the packing technique that Sony Repair uses. I just had to send a 60-pound amp to them for repair that way, using the same box that they used to send it back to me.
From what my scales will tell me, the two speakers weigh in at 62 pounds each. The total of the rest of the system is 170 pounds (80-pounds on one leg and 90-pounds on the other). That makes for a total of 294 pounds net. The 3 pieces of electronic would ship separately as would each of the speakers. The wooden cabinet would ship separate from the metal frame base. It would be packed with the two speaker stands, the speaker covers, the remote and the miscellaneous interconnects. That makes a total of 7 boxes, two at 70 pounds each for the speakers, four at 40 pounds each for the electronics and wooden cabinet and one at 25 pounds for the 3 metal stands. All sent from Tulsa, OK, 74105. Check on-line with UPS or Federal Express for shipping each weight package from me to you. That would get you pretty close to the cost.
