Baffle diffraction anyone?


As long as the
frequency response of the replacement tweeter is
adequate, the main problem is matching levels. Get a
replacement tweeter that has the same sensativity and
the replacement will work.


Nope. Tweeters can display superficially identical
sensitivities and responses while having very different
electrical and/or acoustical properties.


You should have no problem naming some of these
properties. Otherwise,
one might think that you're talking out of your ass.


Chill man, François has it right.

He says:

"Tweeters can display superficially identical sensitivities" which
basically means dB/watt.

"responses" which means general frequency response, which basically means so
many Hz to so many Hz within so many dB.

"while having very different electrical (properties)" which basically means
impedance curve.

and

"(very different) acoustical properties" which bascially means things like
directivity.

All very true.
