So if you like to party.
This Teufel Rockstar Go 2.0 is quite loud,
not suitable for the own four walls if too loud, if the volume does not exceed the room volume you can hear good quality and music, even in the flat.
With the Bassbooster app, you can regulate the bass so that the sound is perfectly tuned to the speakers and not tinny.
There was a lot of talk about the speakers on Google, unfortunately not much good, it's true that the speakers no longer have bass at a certain volume! That's why you need the Bassbooster app for your smartphone or iPhone.

Very loud for this size and price. I am satisfied.
Greetings, Hardy
