lappellation 7.1 of this product is purely commercial! Please note I do not say it is a bad product, on the contrary. After some adjustments, the sound of the bar perfectly transcribed dialogues, collars surround effect (without unn get true 5.1) and has a discreet but effective subwoofer.
In short I recommend it. Its finish is superb and for 400euros you have a scalable system that can turn into a real 5.1 (with denceintes addition) and can decode HD audio formats.
