So after an eye opening first part of the test we must now figure out
how the drivers work as a whole. I have tree different tweeters to test
the stock tweeter, a soft dome tweeter I had laying around and the ribbon tweeter that was my test unit for further evaluation.
As you can see there's two traces on the frequency sweep, the bottom
one is the active sweep and the upper one is the actual paused graph.
The first unit was the stock "SuperTweeter"
This was a pleasant surprise, and you can see why it so pleasant
pretty flat with no surprises anywhere in the frequency band.
Now this could also be interpreted as safe, boring, and un-exciting.

usable frequency is 3k or so which is very obvious as it starts to dip around......3k.
I am replacing this unit with something that can be X-over around
1.5k-2K and with the electronic X-over I can make a smooth transition
between the two drivers.

I might also try to bypass some switches to see if freeing up the drivers
from the switching network makes a difference.
Hope you guys enjoy the testing phase of my quest for better sound.
