Actually the S2 above 8Khz, or what ‘nl’ calls the “breakup range”, is something that I absolutely certainly would like do NOT loose. I very much like what S2 at it’s 10-12Hz. It might be a bit brutal in some cases; I reported it at the beginning of my years with S2.  Now I have no problems and I know how to play S2 to take advantage of all lucrativeness of it’s upper region. There is a few other reasons why I I would like do not truncate HF from S2 but do exactly opposite: to feed it more.

The channel above the S2 is a different matter. The idea to have another small diaphragm driver is fine. I do have a number of tweeters including my beloved TN51. What I would like to find out why the Water Drop does not do it for me anymore. The Water Drop is unique in Macondo’s’ context as it has wide horizontal dispersion (Macondo is installed across a wide wall) and it has narrow vertical dispersion (as it shot in the opening between MF and Fundamentals horns).

The car people say that if an engine does not start then there are only two reasons: no sparks or no gasoline flow. I think the very same with my tweeter. If it does not do what I want then it is ether a problem with the tweeter or with the amp that drives it. Since the tweeter was not change I need to review the amp that drivers Water Drop. I do have theoretical criticism for this amp, primary by the fact that it does not follow my rule of “open top” (similar to the idea of “open bottom” in LF sections). The design of the HF amp itself contains a well-defined HF limit, what I would like to see ONLY high pass filter with  no low-pass at least for 10x. I need to experiment with this more to see what is doing on.
