The tweeter RTC19 alone and with original passive filter.
Notice the yellow is with original passive filter. Looks like filter toooooo much :(
It is now effective only from 4kHz to 17kHz +/- 3dB.
Tweeter is the most important component in the audio chain. It lets the bass go up front, it also lets the bass sound real. Without an extremely good tweeter the entire tonal quality will not be good.
In this case, this is a bad tweeter.
