Where Can I Get Custom Made Foam for Speaker Box?

I have a pair of Mirage OMD 28. One of the shipping boxes had to be thrown out after a basement flood. I found a company that will make me a matching box but they don't make foam or styrofoam for their boxes. I need a company who can make foam that will mold around or fit around an 83 lbs speaker inside a box and hold it securely. The Mirage speakers have a rounded cabinet. Any ideas?

Thanks
