Thanks Eric,

In my G300, all three ribbon circular tweeters start coming in at around 5,500Hz, with the center tweeter full range, and the top and bottom tweeters starting to roll-off at 8,500 Hz.

A far as those ribbon tweeters, they are not cones or domes or slot ribbon/panels. What they are, are actually ring radiators. Hence, they are neither circular drivers nor are they line sources. As ring radiators, they act as a hybrid of the two types and they are not supposed to suffer so much from comb filtering. (This is what they say... Probably Jim has some comments to make to the above statement)

Coming to think of it, going from 3 to 12 tweeters is risky (because there is no way coming back), but as far as my present 3-twt's status, I feel quite happy with it and I will stay like that, for the time being...
