Very strong bass and drive a subwoofer is required. The power supply is sufficient slack off for the two Canton. Lauter I do not want to hear on your PC. If you come with the regulator means 12 clock position, then the amplifier or the power supply is overwhelmed and then drop outs. At constant higher volumes may be recommended the replacement of the power supply.
Just for fun, I had the little sometimes connected to a pair of Canton Ergo RC-L and that's enough really for a lot more than low volume. Its appearance like it very much and the blue lighting around the volume knob it integrates very nicely on or under a desk.
Besides an on / off switch and a volume control, no further settings are available. Should he really come on the stereo system to use, ups and downs can not be readjusted. But is just the perfect way for my purpose. I usually regle anyway after and if need be, you can do that easily on PC.
I have no special sound card and am satisfied with the sound of the onboard sound card. For a little more high-fidelity then recommends a better sound card.
Conclusion: For little money, a nice way to spice up sound on the PC properly. Do not regret the purchase and would bring it to me at any time.
