That depends on what you want the system to do. Most soundbars nowadays eliminate the need for multiple satellite speakers by combining several drivers into a single unit. They're great for enhancing TV and film audio as well as music, but can lag behind traditional systems when it comes to creating true surround sound. Traditional systems with a receiver and speakers allow you to customize your setup and avoid annoying echoes that can come with tall ceilings or narrow rooms, but they also require much more space to set up.
