Need to Contact Angstrom Original Obliggato ????

Hello. I have a pair of the original Angstrom Obliggato speakers. One of the tweeters on the back is not working. I tried to contact Angstrom with no luck. Are they still in business? All I could find was distributors selling their products. I need help identifying/removing and or buying a rear tweeter replacement. Any help would be appreciated. Good listening, SonnY :)
If I'm looking at the right speakers, the tweeter appears to be made by Focal. Its an inverted titanium dome. You shouldn't have any problems getting one. I would pull the tweeter out and look for a model number.
