Things to consider…
>>> Physical size
The bars on test vary in size and the largest ones look odd with a small TV set. Try to match the sizes of both devices.
>>> Expandability
Some models are quite self–contained, others come with a subwoofer, and others have the option to add more speakers. Consider if you need this.
>>> Extra features
Most of the units on test are much more than just a speaker. You’ll find features like AirPlay, support for Alexa, access to Spotify, and more.
>>> Sonic performance
Although the bars on test are designed to provide a home cinema experience, they do have strengths with playback. The inclusion of different modes for movies can help with different sources.
