Had the small for the kitchen. 10 inch TV "Lenco TFT-1026" bought. Since the underground badly from the built-in "Microlautsprecherchen" comes the sound, I connected these boxes. The USB is enough current from the TV to operate these two Böxchen. Now the sound of classes is better even basses are audible. Surprisingly good sound-and at this price! Since the boxes are interconnected with a RCA plug, also the operation is only a box possible.
