CSW replacement tweeter

I have a Cambridge Soundworks Ensemble 3 speaker, and I need to replace the tweeter. It is 2 inch square and about 3/4 inch deep. The only markings on it is on the back of the magnet. It says P13-0280SD 8 Ohm DG012116. Attached are pics. Any advice on a replacement tweeter and where to get is appreciated.


Thanks in Advance.
