Of course this is no hi-reference system. That should be clear to one but at a price of just over 10 euros. Nevertheless, I must say that it was well worth it to replace my old PC speakers to the mini cubes. That latter initially sounded weak and thin, was due to the output volume, which I had turned in my (Linux) System setting to match the sensitive entrance of the old boxes down. After a few simple steps that had been fixed and now the fun began. I used to compare test with my 15-year-old boxing Mozart's Magic Flute Queen of the Night aria "Hell's vengeance boils in my heart" sung by Edda Moser. The piece can be nice treble inspect and which are amazingly clear with the Mini Cubes, on the other hand banged my old PC speaker outright.
Despite the small volume, the Mini Cubes sound relatively full, even on bass they get largely out what is going on the small size. The only criticism is that the upper bass go to their knees (so at about 300 Hz. And a little deeper) with strong momentum somewhat. This results in an effect that slightly reminds of a compression, but also a bit of "rumbling". When I with an equalizer something absenke the range, the effect diminishes but.
All in all this is a good buy with a great price-performance ratio.
