Pros and cons

Pros

A separate wireless subwoofer adds a dedicated bass component without a cable running to the soundbar.
App EQ and dialogue-enhancement features offer sound adjustment beyond a fixed preset.
HDMI ARC and optical connection options give compatible TVs more than one wired setup route.

Cons

The system is 2.1-channel stereo rather than a multi-speaker surround configuration.
