the part is great! Had ordered 2 SoundBar. Once those of Sony and once as a wrote here in the review that the Panasonic 580 is better. Who wants to just bass, accesses to Panasonic! Since coming from the soundbar forward far too little power! When Sony need to be adjusted at delivery first, so that the bass is reasonable, or the heights completely lift. This is once on the remote control with subwoofer + - and even in the Sound menu. Since you can again turn up the bass completely. Who did it, is guaranteed not disappointed! I myself am someone who enjoys listening to bass-heavy and I think that the sound bar is fully sufficient. I am sometimes amazed where the small block herholt this sound. Von wegen boxes popping down by ... In my bangs since by nothing. This part makes a very high-quality impression visually and sonically :-)
