I have to admit that although the Macondo “Water Drop Tweeter” sounds very good but I do not have that “shocking sound” that I got from the “Water Drop” during my initial introduction to it. I kind of always felt it and I thought that I get use to it but now I think differently. What is the problem is that in my current version of Milq my HF channel suffers from the same problem of low-passing die to the high grid impedance as I described above.
I swept my current tweeter configuration with generator and scope. It has second order filter came to play at 12KHz and has cursing 0dB at approximately 19KHz at full power (4V in input). The very same cursing 0dB got all the way up as I raised frequency, we stopped at 73KHz. So, despite it has the same as MF 32K on grid and the same driver but it has not low pass apparently. How that might happen. Furthermore, despite the HF has no limit but the square wave, although it is better but still has not “perfect” shape and in way reminds the squares of the MF channel above.
