Our Verdict
TCL S45H
TCL S55H
Whether the TCL S55H or TCL S45H is better depends more on whether you have room for a subwoofer more than on their performances. Their performances and capabilities are nearly identical, except that, unsurprisingly, the TCL S55H, with its dedicated subwoofer, sounds better with a fuller bass response.
