Short answer: the TCL S55H. It ranks #14 of 16 soundbars with a subwoofer by sound quality, rated 3.2/5, at $119.99. The Saiyin SBP ranks #16, rated 3.1/5, at $79.99, $40 cheaper, which does not close the gap in sound quality.
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. Watch for: Surround and height effects are weak and the soundstage stays narrow, so it sounds like a front stereo pair with bass.
What the Saiyin SBP does well: This compact Saiyin system reaches deep for its size, giving movies real rumble from a small wired sub. The tradeoff: The bass is boomy and gets heavier as volume rises, which can muddy voices and music.
Buy the TCL S55H. It is rated higher for sound quality, and saving $40 with the Saiyin SBP does not make up for the sound-quality gap.
