Well like others have said in other reviews it does lack bass. I went from a high end Onkyo to this unit trying to save space and having wires running everywhere. That being said after playing with several settings I finally got it to where I am happy and don't have the feeling like I need to return it. I will share what I figured out. I also have the rear wireless speakers connected. Like many I had changed my settings to sub +6 Treble -6 Bass +6 First I reread the specs. I noticed that if you have your audio set to PCM the unit thinks it is receiving DTS. In the specs it says for DTS it will only give you 2.0 stereo. For 5.1 it says to use Dolby Digital. Change TV audio output I changed the output of my TV to Dolby Digital and noticed an increase in volume about 1/4 more and noticed bass response also increased. Again referring to specs PCM was only 2.0 NOT 2.1 so sub was only receiving stero input. I then played Jurassic Park and hugh difference in the surround sound especially the rear speakers and there was a noticeable thump in the bass with the T-rex . Now knowing that I had it set to PCM before the back speaker were just stereo copying the front left and right with Dolby Digital the back speakers now are really working in surround mode. Re-position Sub Another thing I noticed is the sub is very directional. Which I would not believe at first thinking bass shakes and is a low should hear it no matter where the sub is placed. I had mine to the side and behind my cough. When I walk over to where it was there was a noticeable difference standing in front of the sub. So I moved it next to the tv and pointed it towards the couch. Again noticeable difference. To the point now I was able to reset the speaker settings to sub +6 Treble 0 Bass 0 and retest the speakers with several movies. I was happy with the results. Again the bass was not body shaking bass but there was the deep thump in the movies where it is suppose to be. One final note when watching DVD or blu rays double check the movie audio settings to make sure that DTS is not selected and Dolby Surround is.

i bought this soundbar several years ago so i could have the center channel for dialog. it didn’t work and i attributed that to my old toshiba tv. i recently bought a samsung au8000 tv hoping to finally get real surround support, center channel support, and audio control from the tv. unfortunately, the soundbar just doesn’t work with arc or earc. the tv reverts back to tv speakers and says that an arc device is not connected. so, now i am stuck with an optical connection and disappointing audio performance lacking center channel clarity :(. upgrading the sw in the soundbar didn’t resolve the problem.

Loved this soundbar when I first got it and hooked it up to the subwoofer and rear wireless speakers but then one afternoon it just stopped working. I only had the soundbar for 4 months. I was able to ship it to their support center to get it repaired but really surprised that it would just quit working. Thankfully it was still under warranty.
