I buy this system a month ago . I would have to say that it be simplicity be amazing , it be sleek and the speaker size be just right . Though , there be a downside : high frequency be barely hear . I install 5 surface mount tweeter beside each cube , and the sound improvement be very noticeable . I strongly recommend to anyone that own this model to do the same , these tweeter be not expensive , and the upgrade be worth the effort . all the system 's other feature be very user friendly . also it have a zoom power -lrb- x1 .5 -rrb- that allow you to see widescreen bigger , as though you be watch full screen . for the frequency response be that I give the system a strong 4 star .
