as we all know for the most part anything is a improvement tfrom the integrated speakers of the tv itself. This setup is a welcomed part of my living room system and i am very pleased with it. the bass, at least in the atmosphere that i use it in, is full and transparent. i am using digital optical connected to the audio out of the tv as opposed to the recommened hdmi out from STB to hdmi in of sub and then out of sub hdmi to hdmi source input of tv. The front speakers offer many connection options to fit your needs. i just have mine on the stand that comes with it. it has presets for audio sound eq, 3d sound, auto power off function, and depending on how you set it up, you can access channel and volume on the tv. using hdmi gives you anynet+ so you can operate it through the tv. digital optical does not give you that option.
Note it is wireless audio communication between the sub and the l/r speakers but it also requires, but comes with, a20 gauge speaker wire connection between the left and right speakers. right speaker has a power source and the sub has a power source as well.
I do not condone what i do, but i will not deny myself the pleasure!
