In my search, I came across the 2.1 system from Blaupunkt. The LS 190 had fairly good reviews, I decided the same for the successor model.
The structure and the connection was very simple, the sound is definitely a lot better now. Above all, the subwoofer contributes a great deal to improve sound. Now comes in films at a little cinema feeling.
The Soundbar is very well made, looks really smart and is very flat. That was important to me, I did not have as are a cheap plastic part acting in the living room.
My conclusion: The SV 1980 EV, while not the cheapest product, but looks really good and sounds great.
