Do not forget that for a soundbar to work, there must be walls and a ceiling to reflect from. That means a square or rectangular room of more or less "normal" size, with a flat ceiling at "normal" height and no missing or half-walls. I've seen soundbars in L-shaped rooms with no wall on the right or left, rooms with cathedral ceilings and rooms where the MLP is well forward of the rear wall. If one has any of these characteristics in their room, a soundbar will not give optimum results and separates are needed.
