Our Verdict
TCL Alto 7+
TCL Alto 8+
The TCL Alto 7+ is a slightly better overall soundbar than the TCL Alto 8+, though depending on your listening habits, you may prefer one over the other. The 7+ feels better-built, and it comes with a dedicated subwoofer, whereas the 8+ has a subwoofer built into the bar. The 7+ has better center and surround performances, too. However, the 8+ comes with more features, including an auto-volume mode and access to Amazon Fire TV 4k media streamer.
