In Reply to: RE: Difference Between Magnepan Ribbon Tweeters: Mg 20.7 vs 3.6 posted by Norman M on April 13, 2015 at 17:25:32:
Actually clipping is probably the main reason why tweeters (cone or ribbon) go bad. Clipping causes a lot of high frequency noise (current) that causes the tweeter to fry. Ideally the fuse should limit the current but in reality that does not happen. You might want to read the article by Rod Elliott (http://sound.westhost.com) on why tweeters blow. My point about excursion of the ribbon is that it may not be a thermal event that afflicted the OP and in that case a thermal protection device, either a fuse or polyswitch, will not help.
As far as replacing the tweeter, it really isn't that hard but good soldering techniques are needed. Try practising your skills before you tackle the ribbon. It really won't take that long to get adept. Remember to use an iron that is hot enough and make sure the surfaces are clean. Also create a mechanical connection before making the electrical connection.
