Where Can I Have a Box Made for Speaker?

Actually, my bad Prpixel you are correct, Mirage is not out of business. I contacted them a while back and was told they do not keep boxes for the OMD 28 in stock or have them for purchase or for free..??? Made no sense at all.

Go to Fedex or UPS and get the closest match and wrap it like crazy with bubble wrap and dense foam. Tape it so it is tight and secure when placed in the box. There should be no wiggle room when done correctly. If shipping~~take pictures of your process and buy the insurance just in case.

I don't know if Dan is talking about Wyatt Acoustics but when I was eyeing Audio Nirvana full range drivers I stumbled upon them for the cabinets.

Try U-line. They carry those heavyweight cardboard boxes, but you might have to buy more than one. I had quite a few of them which were, ironicaly, damaged during Sandy. Wet cardboard is not a good thing. Really.

Go to "custommadeboxes.com". I had a similar circumstance as you but needed a pair of boxes made. They were quick, reasonably priced, shipped with the box broken down to minimize shipping cost, and are willing to make custom orders of one box only if necessary. Many of the custom box makers require a large lot, but not this company. I also found them very friendly and responsive to deal with. As long as you have the original foam inserts, you should be good to go. Good luck.
