Thiele-Small Parameters Database?

Recommended Posts

Does anyone know of a thiele-small parameter database or where I could go to get this info for a slightly older sub? In this case I have an original RE Audio SE 12 d2 that I am trying to build a box for but I cant find the needed info. I called the company and the lady said they don't have the info since they were discontinued.

P.S. there have been two versions released since the one I have.

Any help would be great.
