The TCL S55H is a budget 2.1 soundbar released in 2024 that's compatible with Dolby Atmos. It comes with a subwoofer that connects wirelessly, which the manufacturer claims will combine with the 'dual horn echo chambers' in the bar itself to enhance bass performance. The bar also features some technologies that are more commonly found in higher-end bars, like AI Sonic-Adaption, which tunes the output to your room's acoustics, and 'Tutti Choral,' which works with compatible TCL TVs to utilize the TV's speakers as a center channel that supposedly improves Atmos performance.
