Acoustic Zen - blown tweeter - out of business? replacement?

I doubt AZ makes their own drivers so have you gone to madisound  to compare tweeters?  Maybe checking the resistance of the working unit can help narrow the choices

If I was you I would call Millersound speaker repair and inquire with Bill regarding the possibility of repairing your tweeter?  They are absolutely top notch.

Finally got an answer on the phone, will be sending the tweeter in for repair!  Hopefully it will turn out great!!

Thanks for the Millersound recommendation.  The AZ tweets are proprietary as far as I can tell.. thank goodness there is someone at AZ.

Sorry for the delayed answer... life has had me busy.  I received the tweeter back from repair and it still took me a month to get around to installing it.  It takes solder connections, so it isn't just sliding on the connectors and screwing it to the cabinet.  This is the better way to connect drivers, just had to get my soldering rig out.  The new tweeter works Great!... now there is balance to the system and I can get to enjoying some music again.  Acoustic Zen is alive and well, a small company stretched to the limits perhaps with time, but once you get in contact with them, speedy response and fantastic results.

Robert at AZ can be a little hard to get a hold of sometimes, as he is a very busy man. But once you get him by email or phone he is very helpful and a man of his word.

I have been using his cables and power cords for years. 

Happy customer!

Wishing AZ the best.
