What is a home theater system?

Thumbtack Editors

A home theater is a combination of a large-screen TV or projector and hi-fidelity surround or stereo sound — essentially, an entertainment center made to mimic the experience of going to a movie theater to see a movie. The size of the screen plays a large role in this experience, but the sound is also important. With surround sound, you can hear sounds not only on your left and right but also in front of and behind you.
