You are correct. The cost of the speaker is no reflection on the quality - especially the tweeter.
The Excel Millenium Sonotex soft done tweeter has the best waterfall I have seen. It is expensive at around 200 euros per unit and therefore very few manufacturers use it.
Since most speakers are fairly good in frequency response the waterfall plot plot is far and above the most important speaker measurement. Another key plot is the dispersion horizontally.
Unfortunately not many folks understand the importance.
