That was supposed to be a "secret"... The tweeter is actually not lower cost. We haven't decided what we would bring back for the domestic market. Dennis hinted earlier that if we bring it back, it would be a little different.Thanks for sharing your thoughts! I have a pair of the Minis and appreciate them for their overall sound quality. There is an even newer version using a new, lower cost tweeter overseas. This is not using the AMT.
