You can install it 1.5 meters from the floor if you are fixing it on the wall. You have to observe a central placement so that the speakers also have a place to fit.

Another way of placing the television is using the television stand. It has to be at the center and a considerable height. A good height will be almost equal to the speakers to balance the visuals and the sounds.

Another thing that you will need to consider is the height of the speakers. They have to be in a position that the listeners will have direct listening. This means that you have to consider a position that will match the height of the sitting positions. If you consider getting a stand, then you have to be specific about the height.

Installation on the walls must also consider the height not to exceed the one you need. Next is the angle that you place the speakers. They should be such that the sound meets in the middle and then spreads around the room. Considering an angle of 45 degrees is the best thing in this case.
