ID a Tang Band 8" Sub Driver

[johns]

Had this stashed away in a bin. The model and serial number have been bleached away. Thinking it might make a good office sub. Can anyone help ID the model and then I can try to find the driver parameters. It is a single 4 ohm voice coil.

Different frame. Magnet LOOKs smaller? Also, the OP's LOOKs like one of TBs gold poly cones??

Thx for the assistance. The diameters of the magnet and frame match the diagram in the link. The two depth measurement are off by 10mm. What I have is shallower.

The cone material feels like paper to me. Nothing like my poly cone Peerless drivers.

All the TB 8" sub drivers I found, tend to be more ideal for a vented enclosure. Given it heavy magnet, think this would be as well. If I can't find out what model, can just go with a 1 cu' enclosure, and tune as best as posible.
