TVs are getting to slim and small now that the speakers are never going to be able to create the kind of audio experience that was intended for you as the listener. The idea of surround sound is to give you the experience of immersion — being in the movie or show you’re watching. Just like we’re immersed in the sound and experience of our lives. The number of speakers depends on the size of the room and the type of room you’re in, whether it’s a living room, or dedicated home theatre. At the bare minimum we recommend you get a high quality sound bar and sub woofer to ensure you’re hearing everything correctly when you watch tv.
