The TCL Alto 5 and the TCL Alto 5+ are pretty much the same soundbar, but the 5+ comes with a powerful wireless subwoofer. Therefore, it has a much more present bass, although it’s overdone a bit and the overall sound profile is very boomy and cluttered. If you listen to a lot of bass-heavy content, go with the Alto 5+, but if you’re on a tighter budget and mainly want to upgrade your TV speakers for stereo TV shows or the news, the Alto 5 is a better option.
