A 5.1 soundbar is a worthy investment if you want to upgrade your sound system. Compared to the 2.1 version, 5.1 has more speakers, thus better sound production. It’s considerably louder, too, without the cracking or frying sound that you’ll usually hear from cheap speakers.
Aside from that, a 5.1 soundbar is the best option if you’re setting up a home theater. It will give you a better listening experience through its immersive and solid audio quality.
However, it’s also important to note that 5.1 soundbars tend to be more expensive. This is understandable considering that it’s an upgrade from the previous 2.1 models.
