TCL S45H S Class Sound Bar vs Samsung HW-B400F Soundbar

The TCL S45H is the stronger pick for most people: it decodes Dolby Atmos and DTS Virtual:X, runs AI Sonic room calibration, and pushes up to 100 W from a 2.0 bar with a bass reflex port. The Samsung HW-B400F is a simpler 40 W 2.0 bar with Bluetooth, HDMI, optical and USB, and it is lighter and smaller. Neither includes a subwoofer, so bass stays modest on both. Owners rate the TCL well at 4.3 out of 5 across 267 ratings; the Samsung has fewer published specs and no stated immersive format support.

• Choose the TCL S45H if you want virtual surround from Atmos and DTS Virtual:X, room calibration, and more power from a bar that still mounts on the wall.
• Choose the Samsung HW-B400F if you want a compact, light Samsung bar for clear dialogue and basic Bluetooth and HDMI hookups without immersive processing.
