Fake performance

I can not understand at all the positive reviews. The sound of the satellite is tinny. The bass is muffled. Particularly disturbing is a steady hum, which is indicative of a bad power supply. Absolute "tip" is the specified power of 50 watts RMS. After my first estimates come as a gut feeling than 10 W to. I wanted to know more precisely: If I have a consumption capacity of no more than 23 watts in importing a "pink noise" coming to my optimistic estimate only about 10 W to 15 W to the speaker. With so-called "pink noise" the entire frequency spectrum is reproduced by measurement. It is used to determine the real continuous power (Watts RMS). Although my test setup is certainly not verifiable, the measured values, the specified performance by far can not be achieved. Who does not believe, "pink noise" is available from the Internet and a simple power meter should now each have at home. The loudspeaker can only significantly less than the measured consumption arrive.
The unit returns to the justification did not reach power and mains hum.
