You might choose a soundbar for your indoor audio for several reasons, primarily related to convenience, and space-saving design. Soundbars are designed to project sound forward, making dialogue much clearer and easier to understand, especially in scenes with background noise or music.
Soundbars are slim and compact, fitting neatly under or above your TV without taking up much space. This is especially beneficial in smaller rooms or apartments.
They are generally very easy to set up, often requiring only a single connection to your TV via HDMI ARC or optical cable.
