canman Posted July 24, 2016 Report Share Posted July 24, 2016 Found a tweeter for ar3a and wondering if compatible with ar3. Series # on are 3 is 69xxx so late production. Thinking of getting just in case. Thanks for advise.... Link to comment Share on other sites More sharing options...
RoyC Posted July 25, 2016 Report Share Posted July 25, 2016 The 3a tweeter does not work well in the AR-3....generally speaking, not enough output. Roy Link to comment Share on other sites More sharing options...
Sonnar Posted July 30, 2016 Report Share Posted July 30, 2016 The AR 3 tweeter is surely more efficient and linear. Could be replaced by some 1" scandinavian ( SEAS ) dome ? Link to comment Share on other sites More sharing options...

The AR-3 tweeter has very unique mechanical properties, and a very low dcr of just under 2 ohms. Roy Link to comment Share on other sites More sharing options...
JKent Posted July 30, 2016 Report Share Posted July 30, 2016 So..... if the OP wants a spare tweeter for his AR-3 "just in case," he might want to look for an AR-2 or 2a tweeter IIRC. Is that right? Link to comment Share on other sites More sharing options...

Is that right? Not the AR-2, but the 2a and early 2ax were equipped with the same AR-3 tweeter. Roy Link to comment Share on other sites More sharing options...
Sonnar Posted July 31, 2016 Report Share Posted July 31, 2016 What is the technical reason of the low impedance of AR 3 ? Link to comment Share on other sites More sharing options...
