Anyone wanting to sell their original Hales T3,T5, T8, TCenter Vifa DG26AG-38-04 tweeters please get in touch. They all used the same tweeter. I rebuild the Vida's buy rewiring the diaphragm if its just voice the coil that burned out. As long as dome and surround are not damaged the repair is much better than any replacement using Madisound soft dome diaphragm or a replacement of tweeter with a different model. Once rebuilt and new ferrofluid added they sound identical to original. I can match impeadence to .2 Ohms of a partner tweeter.
These speakers were carefully voiced and changing the diaphragms or tweeters is going to change the magic these spekers are known for.
