You’re going to want a minimum of a 5.1 system to start feeling like you’re in a movie theater. This means a center, left, and right channel along with two surround channels plus a subwoofer. This won’t feel exactly like the cinema, but it’s the first big leap beyond basic speakers in your television. You can achieve this with a single soundbar plus a separate sub, and if you’re not sure how deep into home theater audio you want to go, that’s a perfect place to start.
