The Ls are processed sound, I like visually, but initially produce a highly unpleasant brassy, clanging sound in the high and upper middle frequencies. In addition, deep (er) frequencies imperceptible. By adjusting means "characteristics of the speakers" (Win 7) the sound finds, however, a remarkable change for the better, is: the false noise disappears completely and a - !! for this price !! - very acceptable, acoustic overall result is achieved (details / setting values : see image). Over the long-term quality can say nothing binding and here I am, however, construction / systemic (no mechanical parts) quite confident. Otherwise, this review will be updated accordingly.
