Joe,
The speakers were built to the exact dimensions listed in the instructions, however, since they were built with 1" MDF they are slightly larger (by a half an inch or less). The size is 12 x 12.5 x 36. They are very heavy - probably 80-90 lbs. each. Boxing and shipping would not be cheap. You could easily build a new cabinet for less than the shipping cost and make them look as good as you want. I could ship the drivers, crossover and damping material for a lot less. My current cabinets are finished with a spray on Granite Stone gray finish. If you are still interested, I can send you a picture. And if you would like the cabinets, I would advise taking the drivers out and packing them separately. I believe I paid $450 for the kit a few years back. I would sell the drivers and components shipped for $200. As I mentioned earlier, I have the original manual that describes in detail how to build cabinets for the speakers. If you did not want to build them yourself, a woodworker should be able to do a good job assembling cabinets for you.
