The ideal scenario is to have your TV wall-mounted, and the Sennheiser below it, either on a shelf/rack or wall-mounted itself. Even so, you need to take into account the Sennheiser’s 18.5kg weight and the extra £50 cost of the dedicated wall-mount bracket. That seems rather galling when you consider that the soundbar already costs over £2000.
The dimensions and weight of the bar aren’t the only things to consider during positioning, either. Like most products of its ilk, the Sennheiser bounces sound off your room’s walls and ceiling to create surround and Atmos effects, and while the mic-driven calibration will compensate at least somewhat for an irregularly shaped and/or cluttered room, there’s no substitute for central placement on a wall and as few sonic obstructions as possible.”
