Download this program onto your laptop to test your speakers.

Download FrequenSee - Spectrum Analyzer to your phone and watch it at the same time you are testing your speakers.

Thx. I did this. With my ears I cant hear something after around 21-25 seconds. But in the app is shown something. At first around -35 - -50dB. Than it gets quieter at the 7.5k mark to -50 - -70 and at the end it gets a bit louder again. But during the complete time you can see a peak in the app.
Does it mean, that the speaker ist compatible?

No, you do not need to be a native speaker. Besides, judging by your writing skills your English is good.
Thx. I hope you are right. I will try it.
