Although TV manufacturers have simultaneously decided to ditch and embrace sound performance on their modern screens, at the end of the day there just is no replacement for a dedicated soundbar with or without a subwoofer.

There are 4 distinct flavors: Bar Studio, Bar 2.1, Bar 3.1, and the transforming Bar 5.1.
