At home I hear otherwise a Harman-Kardon PM640 amplifier, a Technics SL-PG5 CD player and Toshiba Aktivboxen music, besides a musician myself to my demands on sound makes it clear.
For small boxes like this I have no Klangwunder expected but expect good sound at low volume and provide exactly this small "Brüllwürfel". The sound is easy to bassy but the mids and highs come through. I do not mind this. The small remote control is extremely practical and serves the work of the keyboard very well. The workmanship is as usual from Logitech, well. The subwoofer is very narrow what my place ideas very accommodates (about half as narrow as a "normal" subwoofer).
Conclusion: For a low price there is a good 2.1 here. System listening to music and gaming on the PC is well suited. Even at high Laustärken the sound remains good, even if then the bass starts easy to roar and the sound a bit "plastic" and little life comes across. To sound a party not suitable for home operation is more than adequate.
