A:Answer Since this is a true Dolby 5.1 surround system, you may adjust the volume from the front speakers (sound bar) or the rear speakers. You may also adjust the treble and the bass to your taste. I honestly am blown-away by the quality of the sound produced (including the bass) and in a 5.1 audio playback, the surround effect is really quite good! For the price you pay and what you get for your dough, I don't think you can beat it! Hope this helps.
