TCL S45H S Class Sound Bar vs GCZ BT109 2.1 Soundbar with Subwoofer

The TCL S45H is the better-built, smarter bar: Dolby Atmos and DTS Virtual:X processing, AI Sonic room calibration, HDMI eARC and app control in a slim 2.0 cabinet. The GCZ BT109 adds a separate subwoofer for deeper bass and more raw power, but it is a basic 2.1 system with no room calibration and no immersive format support. Buy the TCL for dialogue clarity, a clean wall-mounted look and TV integration; buy the GCZ only if bass depth matters more than refinement.

  • Choose the TCL S45H if you want Atmos and DTS Virtual:X processing, auto room calibration and HDMI eARC in a slim bar that mounts cleanly under the TV.
  • Choose the GCZ BT109 if a separate subwoofer and louder bass matter more to you than immersive formats and calibration.

What reviewers say

TCL S45H S Class Sound Bar

  • 4.3 / 5267 ratings

Owners rate the S45H well overall, with 4.3 out of 5 from 267 ratings. Most praise the clear dialogue and easy HDMI eARC setup for the price. The common complaint is thin bass, which is expected from a bar with no subwoofer.

What people mention
  • Sound clarityPraisedOwners say dialogue and effects come through clearly for a budget bar.
  • BassCriticisedReviewers say low end is weak because there is no subwoofer.
  • SetupPraisedHDMI eARC makes connecting to a TV quick and simple.
  • BuildMixedThe plastic cabinet feels basic, though it is slim and easy to mount.

GCZ BT109 2.1 Soundbar with Subwoofer

  • 4 / 5270 ratings

Ratings average 4 out of 5 across 270 reviews, so most owners are satisfied but a notable share are not. Buyers generally like the bass and the input options for the money; complaints tend to center on clarity at high volume and the subwoofer connection.

What people mention
  • BassPraisedOwners say the subwoofer gives movies and music noticeably more low end than TV speakers.
  • SetupPraisedHDMI-ARC and Bluetooth are described as quick to connect.
  • ClarityMixedDialogue is clear at moderate volume but some find it muddled during loud scenes.
  • High volumeCriticised

Questions and answers

Which is better for movies?
The TCL S45H. Dolby Atmos and DTS Virtual:X place effects around the room, and calibration keeps dialogue clear. The GCZ hits harder in the low end but stays stereo.
Which has better bass?
The GCZ BT109, because it ships with a dedicated subwoofer. The TCL relies on a bass reflex port and rolls off early, so explosions and music lack depth.
Which is easier to set up with a TV?
The TCL. HDMI eARC carries sound and lets the TV remote control the bar, and the wall kit and HDMI cable are in the box. The GCZ uses HDMI-ARC and needs the sub placed and powered separately.
Which lasts longer?
Both are budget bars with similar plastic construction, so neither has a durability edge. The TCL's simpler 2.0 design has fewer parts to fail than a separate powered subwoofer.
Is the GCZ worth stepping up to over the TCL?
Only if bass is your priority. The GCZ costs more room and gives up Atmos, calibration and app control, so most TV viewers are better served by the TCL.
Does the TCL need a subwoofer?
No, it works as a standalone 2.0 bar. If you want deep bass you would add one, but the S45H has no subwoofer output, so plan around its built-in low end.
