A soundbar is the single most impactful audio upgrade you can make to a TV setup. Built-in TV speakers produce thin, tinny sound regardless of how good the picture is. A decent soundbar changes the entire experience — and under $300 you can get systems with real Dolby Atmos support and subwoofers.
We evaluated frequency response, bass output, Dolby Atmos decoding, and connectivity to find the best soundbars under $300.
What to Look For
- Channel configuration: 2.1 (bar + subwoofer) is the minimum for real bass. 3.1 adds a center channel for dialogue clarity. 5.1 adds surround speakers.
- Dolby Atmos: Atmos support is common under $300 now, but look for bars with upward-firing drivers for real height effects, not just processing.
- HDMI ARC vs eARC: eARC carries full-resolution audio including Dolby Atmos TrueHD. Standard ARC is limited to compressed formats.
- Dialogue clarity: A dedicated center channel dramatically improves speech intelligibility, especially for movies and TV shows.
