How to pack speakers w/out original boxes?


Help! I need advice on how to pack speakers,[Dahlquist 9c's], that don't have their original boxes. Speaker dimensions, Height: 23in., Width: 15in., Depth.: 12in.. Does anyone sell boxes big enough to ship these? They weigh 55lbs. each. What other packing materials should I use to protect them? Thank you in advance for your experienced Audiogoner wisdom! I'll take any advice that you all can give me.

I'd recommend a piece of plywood in the bottom of the carton, and perhaps attaching it to the speaker underneath with screws. That's what I'm thinking anyway. Further.. build a mini-pallet for each which will force the shipper to use a hand truck. Please comment on any downside to this idea.
We ship aerospace parts. No matter what box you use buy four of them. Cut two of the boxes up and line the assembled boxes with the cut up cardboard pieces. You will in essence be building a double walled box. Much better and stronger. Double tape all the sides/corners of the assembled boxes on the outside.
Using the methods noted above, you should be in good shape.
Good luck, John
Very good advice here and just wanted to add....I use the heavy duty extra large trash bags to wrap speakers in to keep them clean from the styrofoam debris.
Use the 2 and/or 4 inch round foam noodles especially in each corner. They are usually sold in 4 foot lengths, and can be cut to size across or in half lenghtwise. Use them and double box even if you have the original boxes.
