Short answer: the Infitbo D40CS. It ranks #13 of 16 soundbars with a subwoofer by sound quality, rated 3.3/5, at $98.99; the TCL S55H ranks #14, rated 3.2/5, and costs $119.99, so there is not much of a tradeoff to weigh.
What the Infitbo D40CS does well: In The Hook Up’s 2026 budget shootout the D40CS took the top spot ahead of the Ultimea Poseidon M60, sounding the most dynamic of the group with clean vocals. The tradeoff: It does not play as loud as some rivals, so large rooms may need more.
The case for the TCL S55H: The S55H adds a wireless subwoofer to the bar from the TCL S45H, so movies and music gain the low end that the bar alone lacks. The tradeoff: Surround and height effects are weak and the soundstage stays narrow, so it sounds like a front stereo pair with bass.
Buy the Infitbo D40CS. It is rated higher for sound quality than the TCL S55H and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
