Summary: I purchased this because is was supposedly a newer, better, faster version of the HW-D551 sound bar a friend had. It is not the same. The HW-D551 actually has wires that connect (HDMI etc) to the sound bar that sits underneath your television, this version does not. This version requires that you run wires from the subwoofer to the television and it is the speakers that are wireless?!?!.
