Hello There! Had my LAP340 ordered because I have a LG TV already and wanted to enhance the smooth sound! Just the TV (note size limit!) Draufstellen, connect (with cable or LG TVs on the model that goes partly also wireless) and you're done! There is definitely a strong sound improvement over just watching TV! For me, the sound settings are not enough! There is only the normal sound and the Cinema Sound! Sounds to broadly not bad, but I wish more settings to edit the sound (bass, treble, bass, equalizer). This would require probably a visual connection (HDMI) be given to the TV to set up the screen this! Unfortunately, this is not the case! So I ordered a LG 2.1. HTS system with Bluerayplayer which is total even cheaper than the LAP340. By that I am fully satisfied, sound settings very possible more sound settings and the overall sound is still a lot better than in the LAP340 to my mind. As I said, who has set up additional boxes, a subwoofer and a BD player no place for the LAP340 recommended as a sound improvement! The part is seen for its size is not bad !! Who but the place has had a 2.1 HTS plant recommended as you get more for less money offer! LG
