copy 'n' paste from my original post :

This is a pro-built TC Sounds driver, not a hackjob.
There are only two of them like this. I'm keeping one - buyer gets the other. I'm making changes to mine, so you'll get to say you have a one-of-a-kind subwoofer

It's a custom sub made by TC Sounds. These are the same guys that make Stryke, OZ Audio, a few old Oynx subs, and Eclipse subs. So it is related to an Eclipse.
Cone is from a Stryke, the basket is a stock piece that every sub since the beginning of time has used, the motor is from a home audio driver, and the suspension is specific to this sub.
Xmax is 24.6mm, xsus is 24.6mm, and xmag is 27.9mm.
