Another example of a fuse not protecting the ribbon tweeter.
In any case, you need to find the cause of the failure before blowing another $100 on a tweeter replacement. Consider the cap in the HP filter - if it is shorting then the impedance of the HP filter would be about the same as the shunt coil ( < 0.5 ohm) and this would blow the fuse and apparently the ribbon as well. Just put an ohmmeter across the leads of the cap -- if you get a low reading (should be infinity), the cap is bad.
