In my experience, a sound bar can indeed be sufficient for a small home theater setup. They are compact, easy to install and often provide a significant upgrade from the built-in speakers of your TV. For those living in small spaces or on a budget, sound bars offer a great balance between quality and affordability. However, keep in mind that while sound bars can deliver impressive audio, they may not replicate the immersive experience of a full surround sound system. Yet for most, a sound bar will satisfy their home theater needs.
