I just acquired a pair of Tangent 40 by Klipsch. One of the passive radiators has a tear in it. I am looking for any information I can find on how to get one. I have tried ebay, no joy, There is a tag from klipsch on the back of each, but no model number or serial number. The passive radiator is a KD-13, 12 inch. They sound really good, even with the glued up tear on the passive radiator. Before I purchase replacements, I would like to know if anyone knows a source or a repair facility that will handle this.
