Overview
Not a full surround system with rear speakers, this TCL pairs a slim soundbar with a wireless subwoofer for bigger TV sound. It connects by HDMI eARC, optical, Bluetooth or AUX, and an app tunes sound to the room.
Deeper bass and clearer dialogue than TV speakers in a compact setup are the reasons to buy. Surround and height effects come from processing, so they stay in front of you.
Who it's for
Small to medium rooms and smart TV owners suit this compact system. Large rooms and surround enthusiasts need more channels.
Pros and cons
- Wireless subwoofer for bass
- Room calibration via app
- HDMI eARC connection
- Wall-mount kit included
- Virtual surround only
- No upfiring speakers
- Two channel bar limits dialogue separation
Performance notes
The wireless subwoofer takes over low frequencies so the bar can focus on dialogue and mids. AI Sonic calibration measures the room and adjusts EQ for the listening position. Virtual:X processing widens the soundstage without extra speakers.
