However, one should be wary of the frequency response of the speakers with 'transitory' sine (20Hz - 18kHz) for testing.
It becomes clear how big the variations of the frequency responses left / right.
Interference (here extinctions of different frequencies) broke with me shock-like 'experience' from.
Depending on the frequency (the generator sinus passes through)> in quick succession left LS YES right LS nix + vice versa.
Trying to say:
One would have to have at least 30 speakers, two out, which would have the same frequency response in about. For this, the manufacturing tolerances of the individual loudspeakers built into the boxes are too large.
But this is not about high-end speakers, where the highest quality, selected speakers will be tested by measurement consuming it - the prices are in xxxfachen!
Overall, Teufel Concept B 200 USB a very good amplifier-speaker system for PCs - Ala 'on the world has been waiting for' - and the 2.0 world has been waiting and finally get.
YES, the stereo's even friends and they are making a comeback!
It should also be mentioned that for desktop PCs (Hearing with USB!) At reboot is noisy - so you should pay attention before reboot that volume on the amplifier is set according to low or off standby at the amplifier while to conserve the loudspeakers ,
Mind you it is not at the reboot Störgerauschen an 'incompatibility'.
Fa. Devil himself tested only on laptops, where this error does not occur.
Also you should use a good shielded USB cable that was not supplied at the time of my purchase.
Conclusion:
Then I hear a lot of music on the PC, I am very satisfied with the devil.
However, the note of the speaker frequency response I think is important for interested readers / buyers. Therefore only 4 stars.
That should not stop anyone from buying the otherwise excellent sound system, otherwise 5 star deserved from me.
