I've been using it for less than a month. I don't want to turn it off, all the tracks began to play in a new way, juicy and high-quality sound, crystal highs, voluminous enveloping bass. not bad plays if you connect to a TV and watch movies, no worse than acoustics for TV.
In comparison with their own Onyx speaker, the sound seemed to me with a wider range, the sound has a harmony of frequencies - top, bottoms and middle sound, unlike the same Onyx, where the slope goes to top and bottom.
Of course, this is not a full-fledged acoustics, and sometimes a full-fledged subwoofer is not enough, especially in tracks where there is a lot of bottom (more about hip hop), often the column simply does not take them. But this is not the main thing for me, since the main thing in this column is the purity and harmony of the sound at all frequencies. The speaker is ideal for listening to tracks by Trentemoller, Postihead, Royksopp and similar electronics. The vocals give you goosebumps, you should listen to something from Shade, Whitney Houston when buying and you won't want to turn it off.
