Our Verdict
LG SK1
TCL Alto 5
The TCL Alto 5 is a better overall soundbar than the LG SK1. Both bars have a fairly well-balanced sound profile but lack deep, extended bass. However, the TCL has a slightly better bass performance than the LG, making it better suited for bass-heavy music and movies. The TCL also has a dialogue enhancement feature, which the LG lacks. Neither bar supports Atmos or DTS.
