Here’s a limited-time Amazon deal that’s most definitely worth hustling for: The TCL S45H 2.0 Sound Bar is down to $80 at Amazon right now. That’s a $50 discount for a 100-watt Dolby Atmos soundbar with auto room calibration. For context, $80 is what some people spend on a Bluetooth speaker they end up using twice before ditching it in a drawer and forgetting about it forever.
The S45H is a 2.0-channel bar, meaning no separate subwoofer comes in the box. TCL addresses the potential bass deficit with dual-horn echo chambers built into the soundbar body, which the company rates as equivalent to a 50-watt external subwoofer. Whether you fully accept that claim or take it with a grain of salt, the result is a soundbar that handles low-end frequencies better than the flat-speaker arrays built into most televisions, which is the actual competition at this price point. Dolby Atmos and DTS Virtual:X handle the spatial audio processing, adding virtual height and surround effects without requiring satellite speakers or a receiver.
Fast, Easy Installation
Setup runs through HDMI eARC, optical, AUX, or Bluetooth 5.2, so it connects to essentially any television made in the last decade regardless of what inputs are available. The AI Sonic Auto Room Calibration feature handles the tuning side of things automatically. You run it once through the TCL app after connecting, and the soundbar adjusts its audio output to your room’s specific layout and your listening position. It is a feature you’d expect to pay considerably more for, and it matters most in rooms with irregular shapes or a lot of hard surfaces that would otherwise create muddiness or harsh high-end.
At 31.9 inches wide and 2.4 inches tall, the S45H fits under most televisions without blocking the IR sensor, which sounds obvious but is not something every soundbar in this category gets right. The low-profile chassis keeps the visual footprint clean. A wall-mount kit ships in the box alongside an HDMI cable, a power cord, and a full-function remote with batteries, so there is nothing else to order before you can use it.
Measure the Space
The thing to check before you hit buy on the S45H is room size. TCL positions it for apartments, bedrooms, and small to medium rooms, and that framing is accurate. If you’re running a 75-inch display in a large open living room and expecting it to fill the space, a 2.0 bar at this wattage will fall short. In the room size it’s designed for, the combination of Dolby Atmos processing, auto calibration, and 100 watts of actual output does the job.
During this limited-time $80 Amazon deal, the TCL S45H 2.0 Sound Bar is the kind of audio upgrade that eliminates the most common complaint about modern television sound without asking you to commit to a receiver, separate subwoofer, or an hour of cable management.
