Sure, you may have paid for a top of the line 4K television, but all of those specs listed on the box only pertain to the picture. The speakers used on the front of the unit may be of high quality, but they will only deliver sound to the front of the room. For an epic movie experience, and to feel like you are actually there, sound needs to come from all different directions to trick your brain into thinking that you are actually there. If you are watching a horror movie, for instance, and there is a sound of a door slamming from behind, the sound will come from the back satellite speakers to make it feel like the sound actually came from behind you. Plus, the higher quality speakers will be able to deliver a sound with limited distortion, which will make the movie come to life even more so than if it just had a really high-resolution picture.
