The Hercules speakers have so far been a real higlight. The Hercules XPS 2.0 30 Speaker I absolutely loved it since February 2011 and am of the sonority in both the high and low frequency. For my office I have now appointed me the reviewed here successor and am totally disappointed. I've tried the boxes and wondered about both the lack of volume as well as the bad sound. The boxes rattle even with niedrieger volume, bass are almost not represented. Either I caught a Monday model or the quality of Hercules has vastly diminished. For the first time since I've Amazon customer, I returned a product, the XPS 2.0 30 DJ Club are by no means worth 50.
